Thanks Riad for many wonderful puzzles. These were certainly very difficult and had me frustrated for many hours! With so many unique rules, it was easy to make a careless mistake early on in a puzzle, not be sure where you had erred, and have to restart. But, it was certainly fun and had me focused intently for a long time. Unfortunately ran out of time to tackle the last optimiser!

On the results: it looks like I did not receive any points for my COOL optimiser, and Christian may have been given the points in my place. Thanks again.

Unfortunatly for me, I was Player3, and I made the wrong choice :(
I had also the idea to send your solution (the good one) but I thought mine was easier to check, and I checked mine... too quickly.
Because of many players found the best solution last year on Roman OX, I thought the same players will find easily Roman COOL, which is a kind of transposition... And because of this transposition, I was early convinced that 1200 was the best score to reach.

Definitely, I was too lazy this time : for puzzle 10, I have the same answer than Hugo, and didn't saw your answer, which is so similar :((

Congratulations to all, and espacially to Riad for the conception and to James for his performance !

Hi Riad, not sure I understand. I submitted: 1800#150,150,-,150,-,150,-,150,150,150,150,-,150,150,-,-,150,150#-#-#-#-#-#-#-#-#- (Player 8) and pretty confident it has a unique solution!

Thank you Riad for another great contest.
The puzzles are hard, but we have a week so that is not a problem. It is nice to sit down and solve a puzzle without time pressure.
I kept making small mistakes in the Mirrored Sudokus, I solved it on my 3rd try.

For Optimizer #10 I found 6 solutions with 9 points, and there are 2 more in the pdf. I think this was just hard to find any solution, especially in the bottom-right corner. I expected many people would find 9 points.
But I thought Optimizer #11 was the hardest. On the last day I submitted a 2225 solution, which is the best when going around the edge. Later that night I tried the "S" shape and found the 1818 solution. I thought this would be very hard for people to find, but 14 people did! Great work by all of them. This was my favourite puzzle.
For Optimizer #12 I remembered last year's Roman Ox, which I did not do well with. First I found a symmetrical "tartan" solution, with 6 clues on the top and side (150,-,150,150,-,150,150,-,150). Then I removed one clue at a time, checking for uniqueness, until only 8 clues remained. This surprised me, I thought 10 clues would be minimal. Also surprised that less people tried this.
I looked at solutions with three adjacent clues (e.g. 150,250,200) but these were too expensive for not enough information.

Well done to Tomoaki and Sergey also.
Every year I feel very lucky to win this, maybe next year my luck will finish :)

Thank you Riad for the very nice contest, fortunatly we had more than a week to solve the puzzles. All of them hard but funny and challenging to solve.
The best puzzles for me were tools and borderless ABCD. And the optimizers April contest and snake were also very funny to solve.
Congratulations to all the participants, specially to kiwijam!

Already waiting for next year's contest!

Hi Riad,
