Shared, local and online PvP multiplayer: you can play against a friend in a relaxed atmosphere and have a good time. You can also try playing against a stranger if the game is going to be popular enough!
Full single player PvE matches: 4 supported rulesets (International, Brazilian, English/US, Russian) and a 3 AI difficulty levels to choose from!
Puzzles: English/US and Russian rulesets, a total of 40 fun puzzles which will help increase your understanding of different rulesets and make you a better Checkers player.
I recently realized that people mostly leave everything default, including the ruleset.
That meant that the majority of you were playing the International ruleset, which is not beginner-friendly. So I switched the default one for PvE and local PvP, but in the networked PvP - erroneously - only the displayed name of the ruleset got changed.
From now on, when the Brazilian ruleset is selected in online multiplayer, it will actually launch a match that uses the Brazilian ruleset.
