Play Ultimate Tic-Tac-Toe online
Ultimate Tic-Tac-Toe turns nine familiar noughts-and-crosses boards into one larger strategy game. Winning a small board claims its place on the big board. The twist is that your chosen square directs your opponent to their next board, so every move has a local effect and a wider consequence.
How to play
- Open the game and choose solo, an online friend or same-phone play.
- Place your mark in an available square on the active small board.
- Notice which board your square sends your opponent to next.
- Make three in a row inside a small board to win it. If sent to a decided board, play anywhere open.
- Win three small boards in a row on the large board to win the game.
Modes and a useful starting point
Available modes: solo play, online with a friend, versus play, same-phone play.
The enlargement panel helps you inspect the board you are playing in. Before taking an attractive square, check the board it sends your opponent to: an easy local win can give away a more valuable position elsewhere. You need to read both scales of the game rather than treating the nine boards as separate matches.
