Tiktaxx is a C++ engine for the board game Ataxx. It uses traditional alphabeta methods such as null move pruning, killer moves, and a transposition table.
About the game
Ataxx is a two player, turn-based, perfect information board game created in 1988.

UAI stands for "Universal Ataxx Interface" and is a slightly modified version of the Universal Chess Interface protocol. The only differences are that instances of 'c' for 'chess' have been replaced by 'a' for 'ataxx', and that the FEN format has been altered to suit the game.
"x" are player one's pieces. "o" are player two's pieces. Numbers represent the number of empty squares. Dashes represent blocked squares. The final character shows the current side to play.
Play without a GUI
Tiktaxx supports the 'manual' mode that should be more suitable for entering commands manually than the UAI protocol. A board will be printed in text and moves can be entered with chess-like algebraic notation e.g. g1g3, b6, etc
Some potentially useful python scripts for Ataxx engine development, among other things, can be found here:
