Broken Pieces has started. Enjoy the test. All the Best.

Like all other LMI tests, you can view your scores 100 minutes after you start the test.

Although we've taken extra measure to ensure that the answer key is unambiguous, it is possible that some players enter the answer key in a different format. If you find that you have not got points because your answer format is different, you can claim your points here.

Do NOT post your answer here. Just post the puzzle that has been marked wrong.

Of course, if you don't understand any answer key, it is better to get it clarified here before you start the test.

I just finished the test. Great puzzles. I will not put any technical comments until the test is over. My only advice is do participate in this test, you will love solving these puzzles. Thanks Rohan and Tejal for the great set of puzzles.

Do put your comments when you solve this test.

Also be ready with the Samuari Sudoku pieces cut as suggest in the IB. It will be helpful in the test.

Very nice puzzles.Pretty easy too.I made an error submitting Tapa.Entered the contents of 5th column,instead of 4th.hope it will be considered.
It was time-taking without a printer! :)

No, can't consider that :-)
It will set a wrong trend.

Announcement

ZigZag (Puzzle# 12 with 5 points) has 2 solutions.
Full points will be given to players who submit any of the solutions.

Excellent set of puzzles.
Thanks and Congrats to Rohan & Tejal..............

Thanks a lot Rajesh :-)
Thanks Aditya, Neeraj.

Hope the rest of you enjoy the test...

Tejal/Rohan.

Brilliant test. Congrats Rohan and Tejal!

Nice test, Rohan and Tejal. I liked domino hunt and tents.
I made a typing error in the answer for irregular sudoku, but the error is with a digit which is already given in the puzzle. Please check if you can consider.

I've sent mail to Rohan regarding my B&W solution, please check.

Please send to this id too logicmasteradmin@gmail.com

Considering it as correct, since there is given digit where you have made the typo.

Rohan replied to your email. Rotating/Mirroring pieces is not allowed in any of the puzzles. [Page 2 IB, PB]

Thanks a lot everyone! :)

Thank you for this nice contest. I never used my rubber this much :)

Thanks for the puzzle set; adding in the 'broken piece' very innnovative! Cheers, Dave

Lovely set of puzzles.
I liked the logic in Minesweeper, Tents, Hitori and Loop Finder.
I couldnt find the logic for some of the puzzles like Tapa and Black and White and resorted to trail and error for the time bound test.
The Dominos puzzle was pretty nice since the broken pieces get revealed in the very end.
The other puzzles were relatively easy and hence I managed to save some time on those.

Tejal and Rohan, thanks for the wonderful test :)

Fun but simple test. I made my typical boneheaded answer entry mistake (not counting a 90 degree turn in the zigzag that was made out of diagonal lines) but will simply imagine the score I might have had. Thanks Rohan and Tejal.

Rohan&Tejal: Nice test
Logic puzzles were great, but both sudoku puzzles were very easy, I expected something more difficult.
I made answer error too (unfortunately in most valuable puzzle - In Tents puzzle I wrote vertically connected tents in second answer part instead of tents in diagonal) But Tents puzzle has great logic, I like it most (with Tapa puzzle)

Congratulations to Hideaki Jo, Ulrich Voigt, TAKEI Daisuke for topping LMI test Broken Pieces.

Relatively, we've had slightly less participants, may be because of so many other tests this weekend. 75 (out of 92) got non-zero scores.

Thank you everyone.

For puzzle tests, we've had more time than actually needed, so that more players get a chance to solve most puzzles. But we realize that it is not necessarily the best thing to do. In this test, apart from you, there is Sebastin who got Scrabble Loop incorrect. It could be a counting mistake or a genuine mistake while solving, but to lose 5+46 or 32+13 (out of 100) points because of one mistake is really too much penalty, in my opinion.

May be we should have 2 different targets (minutes) for top players and beginners. But I'm not sure how to do the points calculation etc.

I've often thought bonus points should be awarded even in the case of imperfect submissions, according to something like the following rule:

Calculate (Points earned - 5 * points missed) / (Total points), and that is the multiplier used to adjust from the bonus points the solver would have been awarded. Maybe the number in the formula should not be 5, I guess that is up to the organizers.

So for this exam, someone who makes a mistake on the answer submission (or is incapable of solving one of the puzzles) could perhaps go from 100% of the bonus points to (95 - (5*5)) = 70% of the bonus points. I believe the multiplier should be large enough to discourage solvers from skipping puzzles (since skipping a 5-point puzzle will cost you much more than just 5 points) entirely but not so large that the bonus points vanish completely due to one mistake or stumper. I also believe those of us who only solve a bare majority of the puzzles should be denied any bonus points, and this ensures that as well.

But enough about bonus points. This was a fun test and shows the true talent of Rohan and Tejal. Not only can they write sudoku puzzles but also these other varieties -- and entertaining puzzles at that! Thank you for yet another enjoyable test.

@Ziti: Very simple, but interesting idea indeed.

I was tempted to do the calculations based on the formula that you had suggested. Click here for the points with adjusted bonus. [As expected, only motris and Sebastian get significant bonus points ]

I think providing bonus point for these imperfect submissions will be correct. Thumps up from my side.

Would like to understand what others feel about this.
