Omok

About this game

Omok is a strategy game where you place stones on a 15×15 board against the AI. Line up five stones in a row, horizontally, vertically, or diagonally, and you win. Choose to go first or second and pick one of two difficulty levels before the match starts.

How to play

1. Choose black (first) or white (second) and pick a difficulty.
2. Tap an intersection to place a stone.
3. On mobile, tap the same spot again to confirm the placement.
4. You and the AI take turns placing stones.
5. Line up five stones in a row in any direction to win.

Tips

• It's just as important to block the opponent's line of four as it is to build your own.
• Positions closer to the center give you more room to extend in every direction.
• You can undo one move per match if you place a stone by mistake.
• On Hard, the AI defends much more carefully.
• Lining up more than five stones still counts as a win.
