Voodoo's Bumper.io has been doing crazy numbers on the App Store of late, suggesting that the .io bubble is far from bursting.

This places an interesting bumper cars spin on the established massively multiplayer arena genre. The idea is to barge your opponents off the side of each compact stage, with each successful kill making you bigger and bargier (is that even a word?).

These games aren't renowned for lasting too long, however. So the question is, if you're tired of Bumper.io but down with the whole .io premise, where do you go next?

Simple. Just check out the following .io games.
