I would be very interested to hear an explanation of how to solve the puzzle below without guessing. For reference, the unique solution is on the right. - - - O - - O X X O X O X - - - - X X O O X O X - - - - - O X O X O X O - - - X O X O X O X O X - - - - - X O X O O X X - - X - - O X O X X O O

Order to fill in the board (1, 2, 3, ... 9, A, B, C, ... N): B C D O 2 1 X 3 G N 4 X M N H I 5 O F E F X O X L K J 6 A X 9 8 X 7 8 O Reasoning: 1. finish column 2. avoid OOO in row 3. avoid OOO in row 4. avoid OOO in row 5. avoid OOO in column 6. don't duplicate column 6 7. avoid XXX in column 8. wrap XX on both sides 9. finish row A. finish column B. avoid OOO in column C. avoid XXX in column D. finish row E. don't…

Nice work! Step 6 was the one that eluded me. Using that principle I've now been able to solve several boards that I previously thought required guessing.

For the 8x8 table there's a trick you can do which I suspect the heuristics never considers (because the rule violation is not 1 but many steps away): if you have a chit of one color on 1, 5 and one more above 5 then any more above 5 can't be of this color otherwise 2-4 all three would need to be of the opposite color and that's illegal.

Same for 1,2,4: 5 is of the opposite color otherwise 6-8 are of one color.

Yeah, finding step 6 took me much longer than any other step. (Followed by step E.)

Do you see a way to make progress on this one without guessing?

A few bits of feedback: - There's no list of rules anywhere. If you forget any rule, you need to go through the tutorial again. - Is the tutorial missing a rule? (It has the "no two identical rows" rule, but it seems like you also can't have two identical columns). - The endgame needs work. Right now it's simply highlighting every square that's wrong, rather than just telling which rule was broken. This is absolutely…

Hi, I'm Martin, the author. Thanks for analyzing the game and the recommendations. I was actually working on your solution a already. So it will be coming up shortly. Also, for those who were suggesting to put it on iTunes and the Play Store, it already is. Enjoy playing! - @mrtnkl
