IO Games

IO games are simple online games where you jump straight into a shared arena with players from around the world. There are no long tutorials and no accounts to create: pick a name, press play and you are in. The rules are usually easy to explain in one sentence, such as grow bigger, claim more land or be the last one standing, but outsmarting real opponents keeps every round different. Matches are short, and when you lose you can restart in a second. Paper.io 2 is a great first pick: draw lines to capture territory, protect your trail, and cut off rivals who wander too far from home. Check back often, because we add new IO games to this page over time.
