Today I'm releasing Surakarta v1.0 for the iPhone (and iPod Touch). It's based on a traditional Javanese game and was included in "The Book of Classic Board Games" published by Klutz Press, under the name "Roundabouts." It currently only has two-player mode, but I plan to release an upgrade to support single-player play (against a computer opponent) soon.
I hope you enjoy the game! For feedback, please e-mail me.
