Xiangqi

Xiangqi (Chinese chess) is played on the 9×10 intersections. Red moves first. Win by checkmating the enemy general — or by leaving your opponent with no legal move (stalemate also loses in Xiangqi).

• General 帥/將: one step orthogonally, must stay in the 3×3 palace. The two generals may never face each other on an open file ("flying general").
• Advisor 仕/士: one step diagonally inside the palace.
• Elephant 相/象: exactly two points diagonally, cannot cross the river, and is blocked if the point in between is occupied.
• Horse 傌/馬: one point orthogonally then one diagonally outward; blocked if the first point is occupied (hobbling the horse's leg).
• Chariot 俥/車: any distance orthogonally, like a rook.
• Cannon 炮/砲: moves like a chariot but captures only by jumping over exactly one piece (the screen).
• Soldier 兵/卒: one point forward; after crossing the river it may also move sideways. It never moves backwards.

Controls: tap a piece and then a highlighted point, or drag it. Play the computer (5 levels) or a friend. The game is drawn after 60 moves by each side without a capture. Undo is available and games are saved automatically.
