.io Games: Casual Multiplayer Fun Online

It's every player for themselves against the masses in these quick and fun MMO io games (sometimes written as ".io games"). Really just the top-level domain for the British Indian Ocean Territory (like .com is for the US), .io has become associated with some of the best browser-based multiplayer games on the web. The graphics are charmingly simple – which means they're not only retro but also great for browser loading times – as is the deeply addictive gameplay. 

Playing io games online means facing faceless foes from around the world in classic games like Snake.is – here with a Tron-like dark-and-neon twist and an endless sea of other live snakes to get in the way of you carving out your own piece of the game board – or completely new, like Dogar.io, where you need to eat to grow and grow to stay alive in this world where there's always a bigger foe ready to eat you instead (and, as this is a Doge game, expect the full list of top internet memes to make an appearance). Just check out the io games list and see which games tickle your fancy.

The basic Snake premise gets more than a dozen different twists, when you trap and dodge other players in a neon world in Lazer Drive, for example. Or go for something completely different, like medieval-themed survival game Wilds.io, where you can customize your own character then try to outlive all the rampaging monsters. Whichever way you play, io games offer endless nostalgia to adults who remember gaming on their calculators while offering the younger generation a new social pastime.
