Ultimate Tic-Tac-Toe
Nine boards. One winner.
The X-and-O everyone knows, reborn with a hand-drawn notebook look — then taken deeper. Switch to Ultimate mode and the board becomes nine mini-grids: every square you play sends your rival to the matching board. Win three boards in a line to take the game. Quick rounds, real depth. Offline. No account.
Three rules in Classic. One twist in Ultimate.
You already know Classic tic-tac-toe. Ultimate mode keeps the same simple marks but stacks nine boards into a single game of foresight and forced moves.
Mark a square
Tap an empty cell to place your X or O. In Classic that's the whole game — first to three in a row wins.
Send your rival
In Ultimate, the square you choose decides which of the nine mini-boards your opponent must play next.
Claim a board
Win three in a row inside a mini-board and you claim it for your colour. Sent to a finished board? You get a free move anywhere.
Win the meta
Line up three claimed boards across the big grid — row, column or diagonal — and the whole game is yours.
The real game: thinking two boards ahead
Classic tic-tac-toe is a solved draw between two careful players — but Ultimate turns it into a genuine puzzle. Every mark is a double decision: where it helps you here, and where it forces your opponent to play next. Hand them a free move and a sharp player will punish it. The Easy AI is a relaxed warm-up; the Smart AI looks ahead across boards and sets traps you won't see coming.
Ultimate Tic-Tac-Toe popularised the nine-board variant of a game first recorded in ancient Rome.Pick your mode. Pick your rival.
Two ways to play — a quick classic round or the deep nine-board challenge — and three tiers of opponent, plus pass-and-play.
Classic 3×3
The original single grid. Fast, familiar and perfect for a quick round or teaching the game to a friend.
Ultimate 9-Board
Nine mini-grids in one. Your move sends the rival to the matching board — a deep test of forcing moves and foresight.
Daily Challenge
A fresh hand-dealt puzzle every day. Keep your streak alive and see how your reading of the boards stacks up.
Smart AI
Looks ahead across boards, sets forcing traps and never hands you an easy free move. Bring your A-game.
Medium AI
A balanced rival that plays solid lines and blocks the obvious threats — the right step up from the warm-up.
Easy AI & Pass & Play
A relaxed opponent for learning the ropes — or hand the phone back and forth for two-player offline duels.
