How to play Spell Chess
Cast an optional spell before making your chess move. Freeze locks the pieces in a 3×3 zone; Jump lets line-moving pieces pass over one selected piece. Each player begins with five Freezes and two Jumps, and each spell has a three-turn cooldown.
- Cast first. Use at most one available spell before moving.
- Make your move. The spell remains active through your opponent’s reply.
- Take the king. Win by checkmate or by capturing the enemy king.

Spin two chess variants together
You spin once, Amog spins once, and the two variants become one game: Atomic Crazyhouse, Three-check King of the Hill, Crazyhouse Racing Kings. Seven slices, twenty playable combinations, and the engine already knows every rule set.
