Thanks David - short and sweet - and definitely well executed. And not forgetting Deb on the ESB too - an entertaining puzzle!

I typed the results for the puzzle 4 BOTH BOTTOM LINES instead of as marked (last second rush) - I wonder if I can be awarded the points for that puzzle


by the way all diagrams (at least all those I solved) were very exciting - and I like this sort of "blitz" contests. easier to find an hour in a (usually) busy weekend rather than 2.5 hours

Yes, awarded. It is taking little more time to check the claims this time because of unstable internet connections, but all the claims will be checked before the final results.

That brings me to the very interesting discussion motris has started.

1) Given a set - e.g. Decathlon - how much time should the test run so that everyone can enjoy the puzzles?
It is likely that many players don't get to solve the puzzles once the test is over. And also there is some incentive for solving the puzzle after the 'official' time.
It will be very interesting to have the points reduce with time. I think Gotroch had proposed something similar earlier.

2) The other issue is players not finding enough time at a stretch.
This is a problem for most especially given that there are so many internet competitions these days, and all of them offer something different.
Splitting into 10 sets is rather difficult to manage, but what about splitting into 2 sets each of one hour?
Those who find it difficult to get 2 hours at a stretch, may take the tests in 2 parts.
Players who needs some warm up can take the full test at a stretch.

Hi Stefano,

yes that is exactly the kind of contest that is being proposed with no time limit.... the best part is there are 3 Indians in the top 4 positions with a canadian participant at 3rd, Cant remember when that happened last time :D

The position might change as the competition is still on and somebody could always solve it faster.

I'm not sure what you mean by "exactly that kind". I thought Headshrinkers is about (very-)hard Sudokus, and that is why the contest has no time-limit.
The purpose is completely different here.

When I say exactly that kind of contest I mean a contest with no time limit... I am not referring to the difficulty level of the puzzles....

The discussion here is about a competition which does not have a time limit. However this type of contest is possible only in an online format ... unless a separate pdf is created for individual puzzles and time for each puzzle calculated when the pwd for individual puzzle is taken from the site.

Very nice set of puzzles, David!
It was nice solving some JUST ARITHMETIC puzzles (Sequences, Strips), instead of the regular GRID-based logic puzzles

Also, for a change, the timing was nice - short and sweet (though i could solve hardly few of them)

Hi David,

Amazing set of puzzles!

Thanks a ton for making my week-end thrilling.

Flip n Sequence & 0-2-5 Mirror was great!

3 Cheers,
Keshav

while submitting the answer for flip shape sudoku , we were asked to submit the answer for the 7th row of the first sudoku, but there was also no. 4 marked in an arrow on the left side of the first sudoku. so i thought we had to type row 4 for the answer. so i got it wrong. it will be very kind of the administrators to look into the matter and if possible consider row 4 as my answer and if correct , grant me points for that.......... akash

Hope you liked the puzzles.

Same thing Akash mentioned, happened to me. Could you please grant me points too.

Done

I entered the wrong key for #4 - I put in the contents of the greyed area rather than the arrowed rows. Any chance of upgrading my score from 'disastrous' to just 'miserable' ?
Nice puzzles - not enough time for me. Will enjoy them later... Thank-you for the contest!

Done

If someone could check my entry for #1, it would be appreciated. I can't really explain it here without giving away part of the solution, but I think the error there should be fairly clear to someone who looks at it. (Unfortunately, the other 0's I submitted are all legitimately incorrect solutions )

Thanks to David for the interesting puzzle set, and especially to everyone affiliated with LMI who contributes to administering these contests every month.

David and Deb

Great test, lots of fun, although as a Maths teacher, I could have done with less adding up.

Time seemed fine to me - I wouldn't expect to finish one of these (and I didn't, obviously) - maybe 60 minutes would have been better, but I still wouldn't have caught the thing that caused me to waste a lot of time on one puzzle (won't say what for fear of spoilers)

Cheers

Very enjoyable set of tests.

I realise I have entered the incorrect key for #4. I entered the bottom row of both puzzles rather than the 3rd row of the right hand puzzle. I'm relatively confident I have the correct solution, although of course won't give it away here. Any chance of rescuing some points for that puzzle???

Would it be possible to check my answer to #7? I separated lines by commas and the system did not like it. Thanks.

Dave, thanks for a very nice set of puzzles! I will definitely finish the remaining ones not to miss any fun :-).

Hi Deb -
I also entered the yellow-outlined areas on #4 as my answers ....

In any case, compliments to David for some very clever puzzles (I ran out of time, so I will enjoy Deb's ESB later).

Best regards

Dave

Aw, I had my first typo when entering one of the FLIP 'n' Fills. And it knocked me down a bonus point bracket!

If it helps, my typo implies that a number ending in a 0 was flipped (which is clearly false). But I can understand being strict about this, and it's not like I'm really in contention for a top score anyway.

Deb - I think there's a bug with regards to the puzzle rating system. I can't seem to give a rating for the two puzzles I had a manual override on the score.

For what it's worth, I thought #3 was a 6/10 and #12 was an 8/10.

Will have a look before next test. For now, I've added your ratings for the two specified puzzles.

Correct answer 2FGHJ. Your answer 2FGHI.
Marked correct.

Done
Many players did this. Given points to both you and others

Many players did this. Given points to you and all others (even who didn't claim).

Checked all submissions for manual overrides. There is none as far as I can see.
