Groove Coaster was originally a fantastic rhythm iOS game made by the creators of Space Invaders Infinity Gene. This year, however, it moves from its humble touch screen roots directly into Japanese arcades. And at the JAEPO 2013 arcade expo this last weekend, Kotaku East got some hands-on time with the game.

Experimenting with new ways to make folks pay for their iOS games, Square Enix releases Groove Coaster Zero, injecting new songs and adapting a free-to-play model to Reisuke Ishida's original musical masterpiece.
