Droppable Xiangqi

This variant of Xiangqi is inspired by a comment.

Pieces

Pieces setup same as normal Xiangqi game, and all having the same movements, too.

In this game, the 象 is considered to be a different kind of piece than the 相, and the 卒 is a different kind of piece than the 兵. However, 士 and 仕 is considered the same kind of pieces. It is as follows:

• 象 is restricted to the black side of the board.
• 相 is restricted to the red side of the board.
• 卒 can move one space toward red side, and while on red side can also move sideways.
• å…µ can move one space toward black side, and while on black side can also move sideways.

Rules

3. Each player can drop pieces only up to sixteen times per game.

5. It is not allowed to drop blocking check.
6. 象 can be dropped only on black side of the board.
7. 相 can be dropped only on red side of the board.
8. 士 and 仕 must be dropped on the diagonals of palace, but you can drop in either palace.
9. Pieces 將 and 帥 if captured ends the game so they cannot be dropped onto the board.
