Editors’ Choice

Another bizarre, hilarious joyride from the makers of Robot Unicorn Attack 2, this action game lets you roll a massive rock through valleys overrun with destructible objects and hazardous obstacles, racking up distance and points at a furious pace. Stylized graphics and an amusing soundtrack make the experience sparkle, and with the game’s intuitive play and tight controls (tilt or touch), it’s a perfect quick-fix.

Simple Fun, Distruction


My daughter and I love this game! We've been playing it for a few years now. Honestly, I have deleted from my phone before but only for reasons like we haven't played it for a while or I needed some space; internal space not emotional space. But, we always reload it from the cloud because it is a fun, funny, simple but engaging game. I would be surprised if we are the only ones who keep coming back to this game. Good job guys.

Incorrect coins for score reward

GZjdjdjd man

Great game, but you cannot fool mathematicians, I found out that if you get a score of 100, you get 10 coins, but if you get a score of 1,000, you would expect to get 100 coins, right? You only get 31 instead! and it gets worse from there, if you get a score of 250,000 (that is the highest score I got so far) you get 500 coins, that does not sound correct, something with the math is off, but other than that, the game is great.
