Strategy games

Play strategy games free on Diceonaut — online, vs the computer, or pass-and-play. No download.

Tic-Tac-Toe — Three in a row wins. Quick, sharp, and surprisingly deep against a perfect AI. The ideal one-minute match.
Connect Four — Drop your discs and line up four — across, down, or diagonally — before your opponent does. Easy to learn, tricky to master.
Gomoku — Five-in-a-row on a 15×15 board. Build threats, block your rival, and outmanoeuvre the AI in this elegant classic.
Quoridor — The award-winning abstract strategy game of walls and racing. Dash your pawn to the far side of the 9×9 board — or spend one of your walls to send your opponent the long way round. Pure skill, no luck. Play online (2 or 4 players), vs the computer, or pass-and-play.
Hullslam — Turn-based slingshot fleet combat in a space arena. Sling your ships with a pull-back flick — you see direction and power, never the full path, so every shot is your own judgment. Firing is a safe chip; SLAMMING your hull into an enemy is the real damage, but it costs the body. Win by pushing your ships through the enemy's exit gate — destroying their fleet alone never wins. Build your fleet mid-match from a protected spawn bay, screen your capital ships behind expendable hulls, and trade cheap mass into expensive targets.
