A real game from the ladder — every board on this site replays a game that was actually played.

Pick a game

Connect 4

Drop a disc, claim a column, line up four before they do.

7×6 · four in a row

Gomoku

Five in a row on a 15×15 grid. Simple to learn, ruthless to master.

15×15 · five in a row

Connect6

Six in a row, two stones a turn — the fair, modern cousin of Gomoku.

19×19 · six in a row

Pente

Five in a row — or take five pairs off the board and win that way.

19×19 · five in a row, or five captured pairs

Hex

Join your two sides of the board. No lines, no captures, no draws.

11×11 · connect your two sides

OOOOOOBB

Dots & Boxes

Draw a line, close a box, go again. Everything is decided in the endgame.

5×5 · most boxes

An opponent worth playing

Three levels for every game, from a beginner that misses blocks to a Master that searches every reply.

Play anyone

Open a challenge in the lobby or send a private link. Clocks optional.

A rating per game

A separate ladder for each one — being sharp at Connect 4 proves nothing on a Hex board.

A puzzle every day

One position, one winning move, cut from a game that really happened.
