Line Up Five

How to play

1. You play first on an empty 9x9 board.
2. Tap any empty square to place your Coral (X) piece.
3. The machine immediately responds with a Sky (O) piece.
4. Connect 5 pieces in an unbroken straight line (row, column, or diagonal) to win.
5. Win as fast as possible—leaderboard rankings are sorted by completion time on victory.
6. Before your first move you can switch to the 15×15 board and pick an Easy, Medium or Hard machine. Each board and level has its own leaderboard; the daily is always 9×9.

About
