Quantum Chess · published · build 24936022
Quantum Chess hit 1.0 today. The remaster soft-launched in May and has been under continuous development since. Sound, replays, in-game guides, puzzle packs, correspondence, keyboard-only play, a proper mobile pass. And with it, a feature that we've always wanted to create. A way to experiment with different ways to play Quantum Chess... The Alchemy League ships today.
A seasonal online ladder where every season changes the rules of quantum chess, without touching the standard game you already know. Fresh rating each season, live or correspondence.
Season 1 removes merge moves and adds a phase dial beside the board. The dial puts a quarter-turn phase rotation on your next move. Phase is invisible on its own, but split a piece back onto one of its own halves and the two halves interfere. In the simplest case, with the interference played right after the split, the dial at rest gives a coin flip, one click lands the piece wholly on one square, and three clicks wholly on the other. That is specific to the most basic state, though. Other moves can change the phase or entanglement between pieces, and mastering the effect means learning to read the phase and entanglement overlays on the board. The dial turns a coin flip into a choice. And with merges gone, a phased split is the only way to make a split piece whole again.
Season 1 runs October 1 to January 1. The queue is open now for unrated games under the season rules, and there's a pass-and-play practice board for learning the dial. Playing rated league games earns the Alchemy board theme when the season ends.
