Groove Coaster Zero has just coasted into the App Store as the follow-up to the extremely addictive rhythm-based game Groove Coaster.

If you haven’t played Groove Coaster on your iDevice, then we certainly can’t be friends. Seriously, though, if you haven’t played Groove Coaster, then you must have either of two valid reasons.

It’s either you haven’t heard of it before or you can’t be bothered to pay $2.99 up front for a game you’re not sure you’ll like.

If your reason is the former, then you’re welcome for having been informed of the existence of Groove Coaster just now. But if your reason is the latter, then you’re free to try and play Groove Coaster for free through Groove Coaster Zero.

That’s right. Groove Coaster Zero is essentially a free-to-play version of the original groovy game that urges you to “don’t just listen to music, game with it!”

Groove Coaster Zero includes the original tracks in Groove Coaster plus more tracks to suit your musical preferences. A few of these tracks can be unlocked for free as you progress. The others, though, can be unlocked by spending coins bought from the in-app shop.

If, however, you have already heard of and played Groove Coaster, then you’re in for a treat when you download Groove Coaster Zero:

As a show of gratitude to the fans that made the original game such a success, those players with the paid GROOVE COASTER installed on their iPhone/iPod touch/iPad are eligible to receive three special limited edition present tracks within GROOVE COASTER ZERO, gifted when the application is launched. These special tracks are not for sale and are unavailable by other means. Even if you’ve experienced the entirety of the previous game, there’s plenty of enjoyment to be had with GROOVE COASTER ZERO!

Designed for both iPhone and iPad, and already optimized for iPhone 5, Groove Coaster Zero is available now in the App Store for free. So, download it now and remember: “don’t just listen to music, game with it!”
