The ROBLOX app is an online video game that involves a massive online community of players. You can build your own game environments using various blocks in much the same way that you would in the popular Minecraft game. The ROBLOX community also includes various worlds that have already been developed, and you can easily join those worlds for exploration.

Touchscreen gesture control works perfectly with ROBLOX. It takes no effort to find a game world, enter that world, and start playing. You move around the map to complete various tasks, and your character can be personalized to fit your playing style.

Since the game is technically a 'freemium' title, it is free to play, but you can find multiple in-app purchases that speed along the gameplay. Most users will be satisfied with the free version. The graphics are surprisingly good for such a large 3D game, and it has more than 30 million daily active members.

This game is truly a sandbox title, which is rare for games that typically get called such. In ROBLOX, you can manipulate every aspect of the game world, and you can then play with what you create to add another layer of enjoyment to the game.
