Choose your board, choose your rules
Set any board size from 3×3 to 10×10 and pick whether three, four or five in a row wins. Lines count horizontally, vertically and diagonally, so on a big board you are always defending several threats at once.
10×10 tic-tac-toe
for people who never draw.
Classic 3×3 always ends in a tie once everyone knows the trick. SuperTac lets you stretch the grid up to 10×10 and decide how many in a row it takes to win, which turns tic tac toe into a genuine strategy game.
No download. No signup. Works on phone, tablet and desktop.
Room for nine players
The bigger the board, the more people can join — your player limit is the board size minus one. A 10×10 game with nine emoji on the grid is chaotic in the best possible way.
AI that scales with the board
The five AI characters play the larger boards too. Vex the dragon looks several moves ahead and will punish a lazy opening, whatever size grid you choose.
Questions people ask
How big can the board get?
Up to 10×10 — one hundred squares. You can pick any size from the classic 3×3 upward.
How many in a row do you need to win on a big board?
You choose. On larger boards most people play four or five in a row, horizontally, vertically or diagonally.
Can more than two people play on a big board?
Yes. Your maximum number of players is the board size minus one, so a 10×10 board supports up to nine players.
Does a bigger board make it harder to draw?
Much harder. With more space and a longer win condition, games turn into a real contest of blocking and building threats.
