Piccolo is an AI that plays the Japanese Othello strategy game at a strong and competitive level. Piccolo uses Negamax Depth-First-Search with Alpha-Beta pruning combined with heuristics to evaluate position strength, and features an elegant user interface.

Piccolo is currently able to hold its own even against some of the strongest Othello AIs, including NTest, Logistello and Edax.
