Just a quick heads up that the iOS version of Sega's classic Dreamcast puzzle game ChuChu Rocket! [Free] has gone free for today. ChuChu Rocket! involves directing hoards of mice around various puzzle boards towards their escape rockets while avoiding dangerous cats and other hazards.

The action is quite frantic and many of the hundreds of included puzzles are fiendishly clever, and the reworked controls work great on the touch screen. Also, there's local and online multiplayer using Game Center for up to 4 players, which is appropriately full circle as the original Dreamcast title was one of the first to utilize online play.

Unfortunately this sale does not also apply to the iPad version, but ChuChu Rocket! is a must download for your iPhone or iPod touch while it's free. You can check out our original review of ChuChu Rocket! from when it released last October, though keep in mind it's received an update or two since then. As with any sale on the App Store prices are subject to change at any time, so make sure to jump on this opportunity as soon as possible before ChuChu Rocket! jumps back to its regular price of $2.99.
