Mobile IO games come in all genres and types, although they have two things in common: they are free and have light graphics. This means that most, if not all, are accessible on any phone, regardless of age or low RAM.

But there are quite a few online. That said, we are listing the best and most convenient ones for playing on mobile.

The goal of every noodleman is simple: throw all other noodlemans out of the ring. However, there's a catch: each character has a "soft body," meaning they have bouncy shaking physics. It can be difficult to fend off other players and even change direction. As a result, each game passes very quickly, making the perfect game for quick breaks.

Image via MochiBits is a land capture game with gameplay mechanics similar to Pokémon Rangers. You are assigned a color and the goal is to dominate most of the board by enclosing other hexes (both unoccupied and occupied by other players) with your own. This is done by dragging circles around your screen. It requires a lot of real-time strategy, so it's great for players who get into it.
