DualChess

Chess, but every capture has to be earned.

Move onto an enemy piece and the board freezes. Both players drop into a real-time mini-game, a duel, and whoever wins decides that square. Win as the attacker and the capture lands. Lose, and your attacking piece is destroyed where it stands.

It changes how you play. A queen that attacks a pawn can lose the duel and die for it, with the pawn still standing. Being the stronger piece stops being enough.

THE RULES THAT CHANGE • Every capture is a duel. Win it and you take the square. Lose it and your attacking piece is removed from the board. • The king can be captured. Attack it, win the duel, and the game ends on the spot. Checkmate still wins too — it just isn't the only way any more. • Your clock stops during a duel, so mini-game time never counts against it. • Prefer it gentler? With the Classic rule, a lost duel only means the capture fails.

FIFTEEN WAYS TO SETTLE IT Pong tests tracking, Labyrinth navigation, Quick Draw reaction, Memory Match recall, Target Practice aim, Tug of War rhythm, Colour Match precision, Penalty Shootout timing, Math Sprint mental arithmetic, Snake Duel steering, Sea Battle deduction, Billiards angles, Bowling a steady swipe, Mini Golf reading the green and Racing the racing line.

Every piece brings its own power into every duel — King: Shield, Queen: Speedster, Rook: Wall, Bishop: Curve, Knight: Magnet, Pawn: Underdog. Which piece you attack with matters as much as where.
