unchess

Chess, unchained.
Unchess is the chess game you'd rather watch – and then want to play. Classic chess stays exactly chess. Everything else is fair game.

Four ways to play
Classic – Correct FIDE rules, bullet to rapid time controls, clean input and no gimmicks.

MultiChess – Four players, one cross-shaped 14×14 board, clockwise turns. Alliances form, break and end in eliminations. Last king standing wins.

3D Chess – A 5×5×5 cube of stacked boards with the Unicorn, which moves along the space diagonals. Knights jump between levels.

Chess Royale – Four kings parachute onto an arena full of obstacles. Grab gold, collect bounties, shop at market stalls and buy reinforcements while the ring closes in.
Power-ups that bend the rules

Switch power-ups on and every player picks three cards before the match. Sixteen cards to unlock, three per match – and each one says in plain words what it does and what it costs.
Freeze an enemy piece in ice, give one of yours a Knight's Blessing or drop a Barricade into a mating net.

Hide a Mine, turn a piece to stone with Petrify or throw an attacker back to its own side with Ejected.

Take a Mystery cube on the board and a random card fires on the spot – unless your chat gets to vote.
Built for streaming

Connect Twitch in the settings – no bots, no OBS plugins, no extra accounts.

Chat triggers power-ups with commands like !freeze and votes in polls. Pick up a Mystery cube and chat decides which card it becomes.

Channel Points rewards for affiliates and partners. A redemption the game cannot play is refunded.

You are the director: presets from Chill to Chaos, cooldowns, caps and who chat is allowed to target. Opponents always see the rules before the match, and one Panic button shuts chat out.

A board that reads on a phone at Twitch bitrate, highlight detection, Steam Timeline markers and optional Twitch auto-clips.
