In r9c78 only one can be 9, so r7c7=45, r7c8=56,
then r7c9=1->r7c7=4, r7c8=6...

Same logic is applicable to 11 in Column6

Only if there is some blank between rule and puzzle image for typing, I can do like this
Do you know the software "HyperSnap"? It's easy to snapshot picture and edit it.

hey thanks for explaining so clearly ..
only one doubt- how did u got that in column 9 the other two digits has to be in r2 and r4..

See the picture before it.

Remember the rule "empty cells cannot be adjacent", and Col 9 only can have two digits more.

hey sry stupid doubt

Maybe this question was answered somewhere before, but I am too lazy to look for it now. In Number Skeleton puzzle does it matter in which direction are the numbers fill in? The IB has also another solution, when you turn it (199, 2X8, 357).
Thanks

Have the solutions to the practice test been vetted? I believe I found multiple solutions for the Sea Battle. And I found 2 solutions for Liar Slitherlink [the cave end in the lower right that surrounds the 1 in R6C5, could also be shortened to only go around R6C4 and still be valid]. Just checking.

All the puzzles from IB have only one valid solution. In the Liar Slitherlink you probably forget to use columns, where is also only one incorrect clue.

The row/column marking is incorrect here. First row and first column should have been marked. The answer key, in that case, is 199#123 or 123#199.

Are you sure there are 2 different ships in each area and not just 2 different ship parts in the alternate solutions? As I made it, I can assure the example is unique.

About the ESB Flip...
Do the "line"s have to mirror one another?
In the example, you don't have to think the correspondence of lines to solve, but the lines were to be finally mirrored each other.

Lines do not have to mirror each other. It is just a co-incidence in the example. (Please check the actual puzzle in FLIP - http://logicmastersindia.com/lmitests/dl.asp?attachmentid=86&view=1 and its solution in page 15 )

I got it.
Thanks a lot!

ODD FILLOMINO i have atleast 3 solutions

EDIT: This puzzle has unique solution. See Serkan's message below.

Really nice puzzles there. Will have to solve the rest later, got muddled up in many of them. Not happy with my performance, but quite happy with my rank I guess. Admins, you can ignore my claim for points, I know even the alternate I gave is wrong. Just checked back. Silly me.

Please send any 2 solutions to Serkan or to me.

And my sincere request : if you really find multiple solutions, first send them to us and we'll do the needful. Your false alarms (not the first time in this case) is of no help to anyone.

That puzzle has unique solution. Probably Anurag didn't read rules well, so probably he broke that puzzle. So please not consider Anurag's comment, that puzzle has unique solution.

This test is over now. Detailed score page is at - http://logicmastersindia.com/M201112P/score.asp

Congratulations to MellowMelon for winning by a huge margin. xevs takes the second spot. willwc is the 3rd position, his first time in LMI podium. It will be interesting to see what effect this test has on the ratings (it will be updated in an hour).

Congratulations also to Branko for being top Serbian player, narrowly ahead of Nikola.

Good to see Rakesh back, and he takes the top Indian spot.

Reminder to self - Do not schedule any test during Christmas period in next year(s). Thanks everyone who took time out during the festive period to participate in the test. Those who couldn't can still enjoy the puzzles.

Could someone please explain to me in FLIP MIRROR SUMS Left board how the 17 clues are filled?

If a cell is visited twice, the digit will be considered twice in the sum
So 17 = 2 * R4C3 + R4C4

Hi,

Thank you very much for spending your time even at Christmas.

Congratulations to Palmer for 1st place. He could finish all puzzles, but Sea Battle... I think this puzzle hurt so many solvers. Also Congratulations to Ko Okamoto (2nd) and William Blatt (3rd).

Test had 20 puzzles, when I made these puzzles I pushed myself because of the title "Best of LMI". As a result of this, many puzzles were hard, I didn't mean that, but it happened. I am sorry for toughness of puzzles. I made a solution file because of this.

Some statistics:
- The puzzle solved by least competitors was Sea Battle. It was solved by 1 competitor. (Two more attempts, but one correct shot)
- The puzzle solved by most competitors was Suroramu. It was solved by 99 competitors.
- The puzzle with the highest rating was 4x4 Diamonds (8.77) and the puzzle with the lowest rating was Crisscross Crash (5.85).
- The puzzle submitted with the highest accuracy was Toroidal Rectangles(%100, 77 competitors), lowest was Sea Battle ( %50, 1/2 competitors)

Thanks a lot for participation,

Best wishes & Merry Christmas,

Serkan
