Tic-Tac-Toe
(Published on 14. March 2025, 00:07 by ebiggie)
RULE SET:
Normal Sudoku rules apply. Place the digits 1 through 9 in each row, column, and box.
There is either a 4-cell purple "X" or a 4-cell green "Circle" in box 9 (the lower right box in the grid) It up to the solver to determine which player wins the Tic-Tac-Toe game. Player 1 (purple), or Player 2 (green). There is only one solution.
RENBAN (PURPLE): All Renban constraints in this puzzle are 4-cell "X's". There must be a set of 4 consecutive non-repeating digits on a purple "X", and those 4 digits may appear in any order. In other words, the X's are not split into two separate lines. Each "X" is treated as a single 4-cell Renban line.
GERMAN WHISPER (GREEN): Adjacent digits along a green 4-cell German Whispers "Circle" must differ by at least 5. The German Whisper circle is treated the same as if it were a 4-cell closed German Whisper box.
KROPKI: Black dots are a 1:2 ratio. White dots are consecutive. Not all dots are given.

Incredibly nice puzzle! The logic flow was perfect, until I thought I was stuck... And I remembered this all was a game of Tic-Tac-Toe!
Beautiful way to incorporate the rule into the game :)
