How to play
You play X. Place your marks in a horizontal, vertical or diagonal line before the rival completes one.
3 × 3 needs three marks. The larger boards need four. Hard is unbeatable on the classic board and uses deep tactical search on larger boards.
Easy plays sensible moves but sometimes misses a threat. Medium always sees immediate wins and blocks. Hard plans several moves ahead.
