When reaching the opposite side of the board, men are "crowned" to pieces called kings.
Kings may move in all directions (up, down, left, right, or diagonally), as long as the path is clear of pieces.
Multiple captures are allowed, and required where possible, for men and kings alike.
If there are multiples different opportunities for capture, the one which takes the most pieces is mandatory (no distinction between kings and men is made).
[2][1][3] Some sites give the rules wrongly, allowing also diagonal capture.
