Both Move at Once

Unlike traditional chess, both players select and submit their move simultaneously — no waiting around. You pick your move without knowing what your opponent is doing.

⚔️

Conflicts & Collisions

If both players aim for the same square, or a sliding piece's path is blocked by the opponent's move, it's a mutual conflict. Both moves are cancelled and you try again.

⚠️

Illegal Move Penalties

If only you make an illegal move, it's a one-sided illegality. After 3 of these, you lose 30 seconds off your clock. Three mutual conflicts in one turn is a draw.

♛

Capture the King

You win by literally capturing your opponent's king. There are no check announcements — you can move into check if you dare. The gamble is yours to take.

🤝

Draw Conditions

The game draws if both kings are captured simultaneously, insufficient material remains, by threefold repetition, or after 3 mutual conflicts in a single turn.

♛

Victory!

White wins by king capture
