Daily Quantum Chess Puzzle

Every day, one critical position is mined from a real Quantum Chess game. Find the strongest move, see how it changes the position, and earn an engine-graded result without downloading anything or creating an account.

The daily challenge uses the same deterministic rules as the full game: movement measures a piece, contact can zap an enemy or heal an ally, and every possibility must preserve one legal chess set.
