All questions related to the 2021 WS+PC Time Trials can be posted here.

This part of the event remains very mysterious ! I guess it corresponds to the "Olympics" part of the main schedule ?

Will there be more informations published before the Opening Ceremony on these trials ? I mainly ask for scheduling purpose ^^

A preliminary version of part one of the Instruction booklet can be found here - (edit - new version up. see below) (and on the main landing page). We are still working out the little things.

The time trials will run throughout the event in short intervals. Each will have separate winners.

Within each 3 hour window, does it matter when we start the puzzle? E.g. will a 5-minute solve right at the start of the window be considered equal to a 5-minute solve that is started halfway through?

Note: A new version of the IB is up, the change is the answer key to Archery. New link - https://www.worldpuzzle.org/files/106/timetrials%20part%20one%20IB%2...

Hello,

No. Time starts at the same time for everyone globally.
Think of it has 33 LIVE events - this is a nod to Nikoli Time Trials from back in the day.
I understand it will be impossible to participate in all events, but we've tried to spread it out so people can give some a go.

Within each 3 hour window, does it matter when we start the puzzle? E.g. will a 5-minute solve right at the start of the window be considered equal to a 5-minute solve that is started halfway through?

To add to what Tawan mentioned above, there will not be any "Start Button" for these puzzles. For every participant, the start time will be recorded as the same time the puzzle goes LIVE.

For the Archery puzzle in the instruction booklet, I believe the solution is not uniqe: 17,29 and 19,27 also seems valid to me.

The first Time Trials is starting in a few hours.

This is the first experiment with LIVE contests on LMI so we hope things go smoothly.

Before the gun fire; we suggest you familiarize yourself with the rules and answer keys and have the PDF loaded and ready. The password will be dropped for everyone at the same time. For those solving online; there will be a button that says Penpa Link which will take you to Penpa.

No answer checking is enabled. You will still have to submit answers on LMI.

The PDF file also has a shortened link underneath the puzzle. You can also access the link by copying the URL there.Though clicking the Penpa button will be faster.

Happy puzzling!

This is by no means an exhaustive list but some tips to help with Penpa+ tool/site for everyone.

If any questions, feel free to post here.

The first time Trial Puzzle Booklet is available to download. The password will show up at start time.

Shoot, I didn't know the word "LIVE" in the IB meant a contest with a fixed starting time. I was pretty lucky to have found out this fact only 1 minute after the beginning, but I suspect a lot others might have missed it due to the same misunderstanding...

Also when and how are the results going to drop?

We were a little concerned about the load on the website and wanted to see how it performs. Refreshing of the results page is a large part of that traffic so we played it safe. We'll run the numbers and release results soon.

The Score Page is now live. We have installed a 2 hour cooldown to control frequent refreshing. Also, we have not implemented the penalties yet, so wrong submissions will be adjusted later.

There is a time error in the instruction booklet. When it says EST 20:00, it should read EST 22:00. This happens across multiple days.

You are right. This escaped me, I will get a new schedule posted.

Time Trial 3: Wrestling starts in 8 minutes. Link - https://logicmastersindia.com/live/?contest=WSPC2021_T03

The fixed schedule is up as a separate PDF here - https://www.worldpuzzle.org/files/106/schedule%20time%20trials%20fix... and is reflected on the landing page too.

To avoid confusion you can also check the Progress link at the top right of the home page which counts down to the start of or end of each event.

Field Hockey puzzle PDF is not available yet, does it still start at 16:00 GMT ?

And yes, it starts as scheduled :)

Archery: 1. Is 29+17, 19+27 a possible answer for the example problem? 2. Can we have the same number in the different boards?

Archery: 1. Is 29+17, 19+27 a possible answer for the example problem? 2. Can we have the same number in the different boards?

1. Yes, it is a possible answer. Sorry, the example is not unique.
2. Yes, you can. You just cannot hit the same number on the same board.

10 x 10 grid is continue or not in field hockey

I don't understand what you mean.

I think ATHARV means if it there can be unused row / column in the middle of the "correct" 10x10 puzzle.

The 10x10 puzzle is continuous. No unused area in between.

The 5th Time Trial will start soon! Link - https://logicmastersindia.com/live/?contest=WSPC2021_T05

In "Archery", I have an incorrect answer but I don't understand why. Seems valid to me. Are there multiple answers possible?

In "Archery", I have an incorrect answer but I don't understand why. Seems valid to me. Are there multiple answers possible?

Share via email to logicmasteradmin@gmail.com and we will take a look. If there is, we can adjust accordingly.

I think the answer key for Archery is a little unfair. I looked at the example, and example answer, and bold underlined words, and felt that it expected all the numbers to be listed.
I see most submissions have penalties, so that appears common. Perhaps the full answer (which includes the official answer inside it) could be accepted as an alternative correct answer?

The document with all the puzzles is password-protected. What's the password, please?

Yes. I haven't been familiar with the puzzles so didn't know immediately what was going on, but this makes sense. I'll speak to Tawan and accept the other answer too. It might take a while to sort out the results page though.

JustinKalef - 2021-11-14 2:54 AM

The document with all the puzzles is password-protected. What's the password, please?

If you are talking about the time trials, the password will appear once the trial starts, you can see the schedule on the landing page linked to at the top.

I'm talking about every single puzzle on the entire site. I can't open a single one without a password. When I download the puzzle booklet (any of them, including ones that have been open for a long time now), the PDF is locked and I get the message 'Enter a password. This file is password protected. Please enter a password to open the file'.

Have you read the F.A.Q.? It is linked to on the home page as well as the landing page linked to above. These booklets are password protected because they are for fixed time contests, and the idea is you do not see the puzzles till your timer starts, so that no one gains an unfair advantage. So any particular contest, once it starts or once you click the start button, the password will appear and a timer will begin to count down, at which point you are expected to print the PDF and start solving.

Again, this is all explained clearly with images in the F.A.Q. which I highly recommend going through.

Are there any instruction booklet for time trials please? I want to confirm some suspicions about the rules

Are there any instruction booklet for time trials please? I want to confirm some suspicions about the rules

You can find Instruction Booklet for Time Trials here - https://logicmastersindia.com/WSPC2021/

The instruction booklet for time trials is on the landing page as all the booklets.
This is the link you‘re gonna find there - https://www.worldpuzzle.org/files/106/timetrials%20part%20one%20IB%2...

I am having significant technical issues that are really interfering with my enjoyment of this event.
I do not have PenPa -- I do not have a printer -- so the best I have been able to do so far has been
to take a screenshot of a puzzle and try to modify it with MS Paint. This proves to be very clumsy,
especially with my virtual pen's habit of turning itself into an eraser at inopportune times, probably
adding at least 40% to my solving times. So far I have only been able to solve 3 puzzles out of 5,
and the slowdown has always made the submissions close before I could supply any answers.
Scoring 0 points on the one day that I thought I would have the most free time is not a promising
start to this event.

I did see that PenPa was automatically connected to the Timed Events (I tried and failed to
solve the recent Football puzzle). Is there any remote chance of that being automatically linked
to the other puzzle events?

in the Hondball time trial is the "-"to be used in the grid or not?

If you are asking about the spaces between the letters, then the answer is NO. It means that spaces in the given letters have to be ignored.

There are many internal reasons why we didn't have penpa for the main competition rounds. If this is your first time, remember you get to keep the puzzles and can practice. All big events are usually offline and on paper, so generally speaking it'd be good to print out the stuff you haven't solved after the event and try it out.

For now, check out the bonus rounds as they will have penpa too. For instance, the King of Kakuro round later today. Also, continue trying the time trials :)

We wanted an event for everyone while also keeping the main competition fair for top solvers. There are a few reasons why having penpa support goes away from that.

Sport Climbing (Multi Skyscrapers): I'm a bit confused about the Haido rules: "clues indicate the size of the building that must be seen from that direction"
Does "the building" mean the first building seen in that direction or any building seen in that direction ?

Does "the building" mean the first building seen in that direction or any building seen in that direction?

The answer is both of these situations are valid. Let‘s say if you have numbers 142365, you can see buildings 146 from the left side and buildings 56 from the right side.

What I meant is: several buildings can be seen from a direction. The clue then indicates any one of them, correct ? I'm not a native speaker, but shouldn't "*the* building" be rephrased as "*a* building" then ?

What I meant is: several buildings can be seen from a direction. The clue then indicates any one of them, correct ? I'm not a native speaker, but shouldn't "*the* building" be rephrased as "*a* building" then ?

I think I could've improved the wording with "the building of that height will be seen from that direction".
For example, a clue 3 would imply that 'the 3-storey building will be seen from that direction'. It could be in the first cell, or any other cell as long as it is seen.
But I think you understand the rules correctly now.

Do we have any ranking table of all the puzzle in time trials?

Sport Climbing (Multi Skyscrapers)

In the example, there are no given clues in the grey cells. Is this the case in the competition puzzle and is the solving of the clues part of the puzzle? In other words, are there given clues in the grey cells and does the rule sets apply only to these rows/columns with the clues, or does the rule apply to all rows/columns even if the clue is not given as in the example?

chiensudoku2000 - 2021-11-14 4:12 PM

Do we have any ranking table of all the puzzle in time trials?

There won't be a combined ranking. Each time trial is separate.

Apologies if I missed a mention of this: In Multi Skyscrapers, is determining the rule-grid pairings part of the puzzle (I suppose Regions and -depending on formatting- Diagonal is obvious) or will they be given?

There may or may not be given clues in the grey cells. But there will be grey cells clearly marked to indicate where a clue applies to 2 adjacent grids.

All grids will be labelled.

The 8th Time Trial, Sport Climbing, is starting soon! Link - https://logicmastersindia.com/live/?contest=WSPC2021_T08

Is Part 2 of the Time Trial just the same 11 puzzle types all over again, or is there some kind of link to Part 1?

There are 33 time trials in total with 33 different puzzles. Hope that clears it up.

In Sport Climbing, answer key C and D's format are wrong.
I think C is 7 digits, and D is 4 digits.

For D enter the answers in all the skyscraper grids.

Ok there is a bug on the submission page. Enter all 27 digits for the last key and click submit all. We will count the submissions and sort it out.

As we have discovered a bug in the submission keys during the contest, we have decided it is best to not make this event count.
While the Submit All button still records each entry, we feel there may have been solvers who have lost time by this bug.
We apologize for this turn of events.

When will the details for part 2 be released? Will the puzzle types be the same or is it essentially a full new IB?

It is fully new. We will release it in about 6 hours.

Time Trials Part 2 IB

The Time Trials part 2 Instruction Booklet is available on the landing page. Here is a quick link - https://www.worldpuzzle.org/files/106/timetrials%20part%20two%20IB%2...
Note that on the landing page, the Time Trials have now been moved below the Social table so that the last table can be allowed to go longer without disrupting other things.

The 10th Time Trial, Badminton, is starting soon! Link - https://logicmastersindia.com/live/?contest=WSPC2021_T10

Is there any chance we could get something on the WSPC2021 page to indicate which time trials have already expired (text? color coding?)? Now that the part 2 puzzles are listed, it's become a bit more cumbersome to find the one that's currently relevant, and we don't have the part 3 puzzles added yet.

Yes, we are trying something. For now we have broken it into 2 tables, we may collapse the 1-11 table once all 11 are done (you'll still be able to click on it to show it, like the Schedule Overview section, in this case)

Also, just a reminder that the WSPC Progress page is an easy way to keep track of the current events.

Results sorted

The Archery Time Trial results are now sorted, with those who entered the "full" keys also having their answers accepted.
Also, we have implemented the penalty system for this event, adding on minutes for incorrect submissions. This wasn't implemented before so there could be minor changes to the results.
Lastly, on the landing page we have separated the two parts 1-11 and 12-22 into two tables. As of now part 1 is viewable by default while part 2 needs to be clicked on to show up. In 4 and something hours when the 11th Time Trial is done, we will switch.

Hi,

For Time Trials, is it possible to record both the times. Time when the puzzle goes live and time when a solver starts the puzzle and also provide two scores for them.

I know that the organizers are pretty busy with the Convention and Part 1 of Time Trials is almost over. But if there is a way to record the time for now and them update the scores after the convention, that would also be fine.

The intention behind it is just to have a fair idea of individual time and ranking for Time Trials as well in case we are not able to start the puzzle at the gunfire.

Edited by kheti 2021-11-15 5:06 PM

We appreciate your concern.

However, the whole idea of the time trials is that race to start and finish as soon as the puzzle is live. We have many other contests where start times are recorded. The aim here is to have something different, with a live solve experience. That is very much intentional.

For the Fencing example, the answer row that's listed doesn't align with the answer row in the diagram. Not a big deal, but I expected you'd appreciate knowing that.

Thanks, I will try to start as many trials as I can on time.

Also, I noticed that if the current schedule of Time Trial is continued for part 3, then Time Trial 24 would overlap with Authors Panel.

Author's Panel : 18th Nov, 14:30-16:00
Time Trial 24 if same schedule continues: 18th Nov, 15:00-18:00.

I am interested in attending the Author's Panel but also would not want to miss starting the Time Trial on time.

Is it possible to make them non-overlapping?

Thank you for your interest, best of luck! :)

Collapsing the other parts of the time trials works great - thank you!

As of now, you can see the top 3 in the page we just posted about :)

You are right. We will accept both submissions and cancel penalties.

The weightlifting example puzzle has quite a few solutions. Interestingly, the given one is none of them (since there is a 3 in R4C3).

Before that, you need to register at the LMI site too. Here is the link you can use - https://logicmastersindia.com/forum/register.asp

Feature request: After the Time Trials are all over, will it be possible to post a single PDF with all of them together? I'm prioritizing the other rounds while they count, and I hope to be able to solve the TT later without having to print out 27 separate files...

Really terrific work all around for this Convention, the community is very fortunate to have so many dedicated authors and tireless workers. Thank you all so much!

On the Equestrian puzzle -- I see two neighboring circles in each puzzle with a 42 in both solutions (I didn't work them out myself), but are the shared digits going to be in the same orientation in both grids? In other words, would a possible puzzle have a 42 (in that order) in the Sudoku puzzle and those digits reversed into a 24 (in that order) in the Kakuro puzzle? I suspect it will be clear(er) during the solving process but just to be sure I thought I would ask here.

If some time passes and this hasn't been completed, I can personally forward the files to you later.

Thank you for the kind words, Ziti.
Regarding Equestrian, there will be similar-looking circles across the two grids. They will not be coded but the identical pattern should hopefully be clear that we are sticking to the same orientation of all the placements. So no, it is not possible for digits to switch around.

You are right. Thank you for alerting us.
There are so many things wrong with that example. Please see the newer IB with this fix in an above post.

In the new IB, there is also a re-wording of Sailing (Nagareru) to clarify the rules.

Sailing:

Could the solution to the example be a rectangle, i.e. could the line visit row 2 column 4 instead of row 3 column 3? If not, why?

Sailing:

Could the solution to the example be a rectangle, i.e. could the line visit row 2 column 4 instead of row 3 column 3? If not, why?

This is a very good question and is precisely why we added "If the loop cannot travel in the wind’s direction upon entering a cell in which the wind blows (such as it results in the loop hitting the edge of the grid, or a black cell), it may not enter that cell" to the new version of the IB (see download link above).

In the example, if the loop travels down from R2C4 to R3C4 it would be hit by the wind and will not be able to travel in the wind's direction as it will crash to the edge of the grid.
Hope this helps.

Great, thanks. I saw the addition, but somehow still thought that the wind was only in the cell next to the arrow.

It looks like the puzzle booklet still has not been uploaded for Rowing, which opens in a few minutes.

On Rowing, my answer key was highlighted in red and I had to use the "Submit All" button for it to work. Is this normal? I was confused for a solid minute or two about what I had done wrong.

I also faced the same issue. The Instruction booklet shows the Answer Key with comma-separated co-ordinates but the submission page expects the answers the co-ordinates with no spaces or any other separators. That's what was causing the issue. I found it after experimenting with the submissions.

There are commas in the IB only to separate the multiple keys to show how they work. We never have commas in the submission page. We will remove your penalties later, other than that something to remember.

That's okay. I don't mind the penalties. My submissions with the commas were wrong anyways for one of the co-ordinates. But the red highlight definitely threw me off a bit.

Ya by remove penalties it means if we see any correct submissions with the wrong format we will resolve those.

Also note that on the landing page, Time Trials 23-33 are currently collapsed by default and can be clicked on to expand. We will switch this with 12-22 when the 22nd one is over.

The instructions for Volleyball contain a line that says "so that numbers repeat in any straight line" and also a "no repeat rule". Based on the example, I think the first phrase is the wrong one.

You are right, it is a major typo. Normal Trid rules apply and "numbers do not repeat in any straight line".
Sorry about the mistake, thank you for alerting us.

The 22nd Time Trial, Tae Kwon Do, is starting soon! Link - https://logicmastersindia.com/live/?contest=WSPC2021_T22

I think there may have been an oversight in the answer key for Tae Kwon Do. This may be a spoiler, though. Anyway, the booklet didn't specify to use units digits, but the answer is marked as incorrect if you put in the full digit string. I'd assume that due to this oversight, appropriate errors will be rectified and the score will reflect the original time of the "error" in the answer key. Edit: This is particularly important for people, like me, who solved using ONLY the penpa link, and didn't see the instruction that was in the puzzle but not the IB.

We understand and will accept the alternate answer key. The penalties will be manually revoked for those affected some time later. Thank you for pointing this out. Apologies for the snag.

How do we get all unshaded cells into one single contiguous region
if they are already separated into 3 separate non-contiguous regions?
Adding more shading will not eliminate the grey shading that
is already present.

The grey shading is for aesthetic purposes only. You may use some other colours to determine shaded and unshaded areas.

The unshaded cells do not need to be a single contiguous region, only the shaded cells need to be. The unshaded cells just have the shape restrictions.

I tried to solve last few Time Trial puzzles in Penpa, but there is no Undo/Redo button.
Is that intentional or is it just some problem on my side?

Penpa has a Contest Mode which prevents solvers from using the undo function, I think this was used for the later time trials.

The clone function can still be used in contest mode.

Please note there is no online solving for this puzzle (it is noted on the submission page too)

Question for boxing - the answer code for example puzzles should be 3,3 right?

You are right. That seems to be pasted from some other puzzle's key. It should be 3,3.

For the Canoeing Time Trial, do we put commas between each co-ordinate? (eg. "H1,J2,J4,I6" or "H1J2J4I6")

No commas or spaces. Only letters and digits. We have put that message on the key space too.

The 32nd Time Trial, Basketball, is starting soon! Link - https://logicmastersindia.com/live/?contest=WSPC2021_T32

Uh oh, the rules for Aqre are wrong in the Instruction Booklet! Aqre has a rule that *you cannot have 4 unshaded cells in a row, anywhere in the grid*. This is not mentioned in the rules, and it is not used in the very-shaded example.
So anybody trying the Basketball Time Trial is going to get very stuck one third of the way through unless they know this...

(For those who find the puzzle unsolvably hard, the rules were missing that no 4 adjacent unshaded cells can appear either, had to look up the Aqre rules during the trial on puzz.link.)

(Edit: posted simultaneously to the above)

We are very sorry about the missing rule. Thanks James and Philipp for pointing it out. For now we have added a note in the submission page which hopefully helps anyone who will try the puzzle in the future. Beyond that, we will discuss it and see if more action is to be taken.

Thanks for the hint about the missing Aqre rule. I spent way too much time on it.

After some internal discussion we have decided that the individual winners of Time Trial 8 and Time Trial 32 will stay, and the medals from these rounds will not count to country tallies. We will sort that out in the Hall of Fame page in a while.

The Hallf of Fame page reflects this now.

A combined PDF of all 33 Time Trial files is available here - https://logicmastersindia.com/lmitests/WSPC_2021_T00_PB.pdf

Note that this is a combination of the competition PDFs as they were without any updates for issues like multiple solutions or wrong rules. One prominent example is, in Puzzle 32, Aqre, there must be a rule added that "there cannot be a continuous line of 4 unshaded cells in any row or column". The other major point to note is that in the Pentathlon, the Word Search has a an alternate solution. If in doubt it may be best to visit the progress page and go to the relevant competition page to see if anything is noted.

Thanks to IHNN for helping us put this together.

The link to this PDF is also there on the landing page in the first row of the Time Trials Table (which is now a combined table of all 33 time trials).

What about all 33 Time Trial Instruction booklet...? (3 files to 1 file)

3 vs 1 doesn't make as much difference as 33 vs 1 so we will probably leave it as it is.

Hmmm.. OK
