Also, even if you finish round1 before 50 minutes, you can start Round2 only 70 minutes after your started round1.

So for example, if you finish all the sudokus in Round1 in 40 minutes after you started Round1, you have to wait for 10+20=30 minutes to start round2.


Also, during the 20 minutes break while you are waiting for Round2, you can click on the 'Refresh' button next to 'Show examples' to see how much time is left. Once 20 minutes is over, 'Start Round2' button will be enabled.

Thanks for the explanation:)

I suggest that the next time you have a multi-round mock test like this one, you treat the two rounds independently, so one can do one round early in the day and do the other round late in the day. There's no real reason not to have this flexibility given the "any time mock" system. It's not immediately apparent that the two rounds have to be taken together.

i have a doubt

lets say i take the mock today with a username.which means i have all the puzzles with me.
and what if i login tmmrw with another ID and submit the answers.this way it looks like i have finished all the puzzles when i login the second time

i don't intend to do this but what if somebody does it like this

I started Round1 but (even after many refreshes) don't get page with the flash puzzles to enter answers... Any idea what's wrong? Thx

OK, used Chrome and it works there... lost couple of minutes, sigh. :(

Chris, whatever you mentioned about multiple rounds is definitely the best one.

Here is my personal opinion :-
First of all, I don't like multiple rounds, when it is Online. Players who solve on paper always loose time because of pdf password, printing etc.
I would always prefer a single longer round than multiple smaller rounds.

thank you for all players who participated in mock test 14 :)
for someone metioned why it has two rounds, the two rounds are designed by different people, it's difficult to calculate bouns if we put all puzzles together. at first, i only want to a mock test with classic sudoku, but i also know many players want to solve variants, so i ask another one to do variants. we want the test in 2 hours because it's better to test players ability in classic and variants, sustained attention in two 2 hours. Deb metioned printing, in my opinion, every player will spend time to print, it's fair. our original intention is everyone will enjoy our puzzles, and harvest by playing our puzzles, i will analysis round 1 after the test end.

These 'Mock Tests' provide opportunities to players to solve Sudokus in a time-constraint-ed environment. This will only help them in 'Actual' competitions.

With 'Any Time Mock', players can find ways to cheat the system, but in reality they will be cheating themselves.

I think there is a grid without solution ....

I do it 3 times and each time, there was a contradiction wich prevented me from continuing the resolution... :(

Fred, which grid are you referring to?

I suppose it is XV. My solution was accepted, but there is one missing V sign between r1c1 and r2c1.

Average Sudoku

Average Sudoku did not have a unique solution:

324 157 698
615 298 734
987 364 125
241 689 573
536 742 981
879 513 246
193 425 867
762 831 459
458 976 312

4 & 8 in Boxes 8 & 9 can be interchanged among themselves.

Please correct me if I am wrong.

Yes, it was on the XV grid... I had a 3 in r1c1 or r2c1 then 2 could not be in r1c1or r2c1, so I put the 2 r1c3 or r3c3, then I can not finish the grid....

And on average sudoku I thought there were 2 solutions, too...

Fred

it's my fault lost a "v" in vx sudoku, i'm very sorry to all.
the answer of average is
324157698
615298734
987364125
142689573
536742981
879513246
763825419
291436857
458971362
in the rule"The cell which value is the average of two cells aside marked with a line.", so if there's no line, it can't be average of two cells.

On the 7th line ... 2-5-8 would mean, that there is horizontal line over 5. So they can't be this way, only the other position is correct.

R7C7 can't be 8 because R7C6 = 5, and R7C5 = 2

oups you're right :) , I had chance to choose the right solution on this grid :bleh:

Fred

That was one tough set of sudokus !!
I liked the fact that the puzzles were all logically solvable (at least the ones that I was able to solve in the given duration)

There could have been more time allotted for both rounds.
I managed to solve only 3 in the variations round, solving a fourth consecutive just after the time was over.
It was a little sad that I wasn't able to try some of the cool sudoku like the Average Sudoku which has a neat set of logic involved.

It is very easy to miss an X or a V while making a puzzle like Sudoku XV, however it does distract the solvers and we need to formulate a process to avoid such errors in the mock tests in the future.
I will start another thread to discuss some of the possible ideas.

maybe because of the missing in vx sudoku, all the reply above are discussing variants, could you give me some reply for classic sudoku. like we metion in IB, all the puzzles are low level technology, 1-6 solvable by singles, 7 solvable by pointing, others need pair triplet and xwing, introduced in many japanese sudoku books. and we alse do some work on guessing part for 7-10.

we know players like to get more score puzzles first, so we put the puzzle seems easier at last with high score. compare with your step and analysis, maybe you will have a new feeling with the ten puzzles, and i wonder someone can tell us your feeling, or you solve time for every puzzle, if all puzzles according with the theme metioned in IB, or something you want to tell us. thank you! :)

Thanks for correcting me. I thought that the converse might not be true, so I didn't check for that.

Thanks for the awesome analysis. Nice way to rate the classics.

I think all the techniques that you have used are absolutely acceptable in competitive sudokus. These techniques can be identified by participants without breaking their head too much or being tempted to resort to trial and error. :)

score / Results has been updated to show the split between Round1 and Round2.

Couple of observations
1. The average score in Round1 is much higher than average score in Round2. So, probably Round2 should have been longer.
2. Many players didn't attempt Round2. (so, either many players are just interested in Classics OR some players gave up after finding Round1 little tough)

Only Zafer completed Round1 with 4 minutes of bonus time. So really a good show from considering many other good players solved only 5-7 in Round1
