How to play
The board is a large 3×3 grid where each cell contains another 3×3 grid. You play as X, the computer plays as O.
Tap a cell inside the green-highlighted mini-board to place your X.
Your move decides which mini-board your opponent plays in: pick the top-right cell — the opponent goes to the top-right mini-board.
Get three in a row inside a mini-board to claim it!
Claim three mini-boards in a row on the big board to win!
If the target mini-board is already completed, the opponent can play in any open one.
