Tic Tac Toe guide
The three-in-a-row classic: beat a bot, share one screen, or challenge a friend online.
What is Tic Tac Toe?
Tic Tac Toe is a two-player game on a 3×3 grid where players take turns placing X and O, and the first to line up three marks in a row wins. On DD Games you can play free in your browser against a bot on Easy, Medium, Hard or Auto, pass one device between two players, or play online.
Tic Tac Toe is the quickest strategy game there is: nine squares, two symbols and a game that lasts under a minute. It is known as noughts and crosses in British English, and in many Indian homes as zero kaata or simply the XO game. Because it is so short, it is a perfect warm-up and a good first lesson in thinking one move ahead.
DD Games gives you three ways to play. vs Bot lets you pick Easy, Medium or Hard, or leave it on Auto, which adjusts the level to your recent results. Each bot has a name and a personality, but on Hard every one of them plays perfectly. Same device is pass-and-play for two people on one phone or laptop, and Online lets you get matched with another player or open a private room for a friend.
How to play Tic Tac Toe
- Pick a mode: vs Bot, Same device (pass and play), or Online. For a friend, choose With friends and share the room code.
- Players take turns placing X and O on the 3×3 grid. X always moves first, and against the bot you are X.
- Tap or click any empty cell to place your mark. The status bar shows whose turn it is.
- Line up three of your marks horizontally, vertically or diagonally to win the round.
- Press Play Again for a rematch. Wins for each side and draws are counted across rounds.
Rules
- The board is a 3×3 grid and each cell can hold only one mark.
- Players alternate turns, one mark per turn, and a placed mark can never be moved.
- Three identical marks in any row, column or diagonal win immediately.
- If all nine cells fill without a line of three, the round is a draw.
- Online, X moves first in every round; if a player leaves the room during a game, that game ends.
Tips and strategy
- Take the centre when it is free: it belongs to four winning lines, more than any other cell.
- Corners are the next strongest squares; an edge is the weakest opening move.
- Always block an opponent who has two in a row before building your own line.
- Create a fork, two winning threats at once, so your opponent can only block one of them.
- If you move second and your rival takes a corner, answer in the centre to stay safe.
- Easy and Medium bots make mistakes you can punish; against Hard, a draw is the best possible result.
