How Ultimate Tic-Tac-Toe works,
in short.
- Step 01
Nine little boards in one big board.
Win a small board the usual way — three of your marks in a row. Win the whole game by winning three small boards that line up across the big board. You play X and move first; the computer plays O.
- Step 02
Your move sends your rival to a board.
Where you play inside a small board decides which big-board cell your opponent must play in next. Play the top-right square and they're sent to the top-right board — shown here ringed in green.
- Step 03
Sent to a finished board? Play anywhere.
If the board you're sent to is already won or full, you get a free move in any open board instead. Keep steering the play until you line up three boards — that wins it.
