Gaming is a pastime enjoyed by millions across the world, and each person plays for different reasons - though one of the prevailing ones is to get lost in an adventure. Open world games are one of the most entertaining ways of doing this; they allow players - whether they're on a PC, their mobile phone or a console - to explore rendered worlds at their own pace and in their own way. Though there will usually be a story to follow, the rate at which that unfolds is largely up to the player. Many open world games also have multiplayer options, allowing people to play with their friends.

In fact, online gaming is one of the most popular ways games are now played. Hours of spare time can be filled playing with friends online, exploring worlds and completing missions, or competing against others. Some of these are even free to play, making them extremely accessible. If these games are open world, they allow players to roam around huge online sandboxes, discovering new things with people they're playing with.

Minecraft has become one of the most popular online open world games, particularly among younger gamers. Though it's predominantly played on a PC, it can also be accessed on mobile through an app. Grand Theft Auto is the most popular series of open world games, with the latest entries also offering online multiplayer options. The Witcher 3: The Wild Hunt is one of the most critically acclaimed open world games in history, even helping launch a Netflix series. If you're looking for open world games you can play on your phone while on the move, these apps are for you.
