Poddavki
Poddavki (also known as Obratnye Russian shashki) is a draughts game based on the rules of Russian draughts, main difference from other draughts games is that a player wins if he doesn't have any legal moves on his turn (either by giving up all of his checkers or having them being blocked). The game is possible because capturing is mandatory. Played in Russia and some parts of the former USSR.
