Russian Checkers or Shashki.
There is some difference between Russian and Classic Checkers rules.
In Russian Checkers, checkers can (and must) capture backwards. The kings in Russian Checkers can move multiple squares backward or forward (diagonally). Kings may jump empty squares before jumping over opponents piece and may land on any empty square beyond the opponent, not necessarily the square right beyond the opponent’s piece. If a king can jump onto a square from which another jump is possible, then it must make that jump. If checker becomes a king after a jump, it must continue jumping as a king if possible. Whenever a player is able to make a capture he must do so. When there is more than one way to jump, a player may choose any way he wishes.
A man or king may not jump over the same opposing man or king more than once.
