Zach Gage's silly take on chess, dubbed Really Bad Chess, has been ported to Android and is out right this instant.
If you're not familiar with the concept behind the game, it's essentially chess but with randomized pieces. You can thus have 7 bishops, 5 knights and any kind of combination you can think of. Your goal is to win with that.
Our own Harry Slater though it was brilliant and he even said that "Really Bad Chess takes a really bad idea and somehow manages to make it a lot of fun".
Seems like something everyone should try, especially for free.
