Five personalities, five difficulty levels
Bub 🐣 plays almost randomly. Pebble 🐢 blocks the obvious. Whiskers 🦊 hunts for forks. Bolt 🤖 plans ahead. Vex 🐲 plays to win and will make you earn every point.
Tic-tac-toe against
five AI characters.
Play the computer at whatever level suits you. Bub the chick is gentle enough for a five-year-old. Vex the dragon thinks several moves ahead and rarely lets a win slip. Free, in your browser, single player any time.
No download. No signup. Works on phone, tablet and desktop.
Change the board, change the challenge
The AI plays every board size up to 10×10 and any win length you set. A 3×3 game against Vex is a puzzle; an 8×8 game needing five in a row is a war.
Practise, then take on people
Sharpen up in single player, then jump into an online room or a pass-and-play game with friends and put it to use.
Questions people ask
How many difficulty levels are there?
Five, each with its own character: Bub the chick, Pebble the tortoise, Whiskers the fox, Bolt the robot and Vex the dragon.
Can the hardest AI be beaten?
On a 3×3 board Vex plays close to perfect, so a draw is often the best you can do. On bigger boards with longer win conditions there is far more room to outplay it.
Does the AI work on big boards?
Yes. Every character plays any board size up to 10×10 with your chosen win length.
Is single player free?
Yes, entirely free with no signup.
