Chess960 puzzles
Solve tactics from real Chess960 positions right in your browser.
Every puzzle here is mined from a real Chess960 game position and verified by an engine: the winning line is forced, not cosmetic. Puzzle names are generated from the structure of the solution, so a «knight fork» in the title is literally what happens on the board.
Filter by tactical theme, rating band or castling motif, or open a starting-position page to see the puzzles born from that exact setup. Every puzzle is solvable right in the browser — just drag the pieces.
Difficulty uses the Shuffle Rating unit, calibrated on real solve results — a 1400 puzzle here offers about the resistance of a 1400 opponent.
