Alquerque (ancient checkers)

Origins

“El Qirkat”, Arabic القرقات, came to medieval Europe via Spain. In France adapted to chessboard, leading to modern draughts/checkers.

Capture or lock in all of the opponent’s pieces. The game ends when a player has no pieces left or cannot make any moves.

Players take turns, each time using only one of their pieces:

If possible, capture a single immediately adjacent opposing piece: Jump over it along a straight line, land on the empty point right behind it.
Your piece may capture additional pieces by doing a sequence of such straight immediate jumps over single pieces, possibly changing directions ("zig-zag").
Remove captured pieces from the game. If no opposing pieces are left, you win.
If you cannot capture, move a piece one step along a line to an empty point.
If you cannot even move any of your pieces, the other player wins.
Note: It is not allowed to jump over your own pieces.

As soon as only 8 pieces are left on the board, the game moves to the inner 3x3 square:

If any of your pieces is on a point on the edge of the board, you may not play pieces on the inner square. You must make a move or capture jump from an edge point to one of the 9 inner points of the board. If that's impossible, skip a turn.
Nobody may go to any of the 16 edge points anymore, not even temporarily during a jump sequence.
