Hello,
Being a chess composer and the author of more than a dozen chess variations, not long ago I proposed a rather interesting and, in my opinion, unique variation of checkers.
In short the rules are: The game is played according to the basic rules of Russian Checkers, with the only difference that you need to capture not only the opponent’s checkers, but also your own, while a checker making a capture changes its color immediately after the first jump. Moreover, if you capture your own checker, then it goes to your reserve and can subsequently be placed on the board.
More detailed rules here: https://www.chess.com/blog/Pokshtya/werewolf-checkers
You can give it a try against a bot on Dagazproject (no registration required): https://dagazproject.github.io/checkers/werewolf-checkers.htm

I received a lot of positive feedback from players of various levels, from simple checkers fans to masters of this game.
What do you think about this game of checkers?
