Growtopia

Growtopia is a free side-scrolling platform MMO sandbox. That means you build worlds online with thousands of other players, out of a wild assortment of weird blocks like Old Timey Radios, Mushrooms, Bubble Wrap, and Magic Bacon Wallpaper. It's a social experience with players crafting platforming challenges for each other, battle arenas, quiz games, item shops, pixel art statues, stories, and more.

With thousands of players online at a time, randomized special events, and new items added every couple of weeks, there's always something new to keep you interested!
