Why this works

Online Chess Puzzles in ChessHole are not about checkmate. They are about move order, reachable squares, and keeping a piece alive after the board changes.

Best first habit

Before moving, count the safe landing squares each piece will still have after its current tile collapses. That single habit prevents most early dead ends.

Who should try it

This page is tuned for brain-training fans who want spatial reasoning and sequencing practice in a chess-inspired puzzle that runs in the browser.

Free vs Pro

The first 40 launch boards are free. Pro is a one-time $4.99 unlock for every proof-built board, unlimited hints, and premium piece skins as they land.
