玩法
- With 2 players, choose "Ultimate Tic-Tac-Toe" or "Vanishing Tic-Tac-Toe"; with 3 players, it's "Three-Player Tic-Tac-Toe."
- Decide turn order and start the match.
- On your turn, place your mark on any open square on the board.
- The match ends the moment someone meets that mode's winning condition, or the board fills up.
怎样获胜
Whoever first completes a line under that mode's rules wins the match — though it is possible for a match to end in a draw.
小技巧
- In Vanishing Tic-Tac-Toe, work backward from when your own marks are about to disappear and plan your line around it.
- In Ultimate Tic-Tac-Toe, where you place your mark decides which small board your opponent plays next — sending them to an already-decided board lets them play anywhere, so think ahead before you place.
常见问题
- How does Ultimate Tic-Tac-Toe work?
- It's a 2-player mode played on a double board — nine small 3×3 boards arranged inside one big board. Line up 3 in a row on a small board to claim it (if it fills up with no winner, that small board is a draw). Wherever you place your mark decides which small board your opponent must play in next, unless that board is already decided, in which case they're free to play anywhere. Get 3 small boards in a row on the big board to win.
- How does Vanishing Tic-Tac-Toe work?
- It's played on a regular 2-player 3×3 board, but each player can only keep 3 marks on the board at once — placing a 4th makes your oldest mark disappear automatically. First to line up 3 in a row wins.
- How does Three-Player Tic-Tac-Toe work?
- Three players — marked circle, cross, and star — take turns on a 5×5 board. First to line up 3 in a row wins.
- Can I play tic tac toe online here without installing anything?
- Yes. The board above runs in the browser, free and with no sign-up, and all four modes work — CLASSIC (ordinary 3x3), plus the app’s ULTIMATE, VANISH and TIC-TAC-TRIO. Once the page has loaded it keeps working offline, so it is fine on a train or a plane.
