Piece guide
❋ Pinwheel is a giant knight: it jumps 5–7 squares in a straight line, turns 90° to either side, and goes 5–7 squares more. It leaps over everything and captures only on the square it lands on.
❖ Ricochet slides like a bishop and may bounce once off the board edge.
∿ Serpent zigzags forward or backward, one diagonal step at a time, left then right.
◎ Wormhole steps like a king, or teleports to its mirror square across the left–right centre. The mirror square can be empty or hold an enemy piece, which it captures.
✥ Grasshopper moves like a rook but lands only 2, 4, 6… squares away. It hops over any number of your own pieces. The first enemy piece in its way is captured if it sits on a landing square; if it sits on a skipped square, the Grasshopper can jump over it onto the empty square right behind it.
⊕ Archer moves to any empty square within 2 tiles (a 5×5 area), jumping over pieces. Instead of moving, it can shoot an enemy queen, king, knight or pawn in that area without leaving its square. It never captures by moving onto a piece.
