In just under two months, a Roblox user-created game called Grow a Garden has become a massive hit.

A fairly new game mode has become one of the most popular experiences currently featured in Roblox, reaching more players than several iconic modes.

Like YouTube, Roblox started as an online stage for young creators. As the company grows toward 100 million active daily users, contributors are making big money selling games.

A 'SpongeBob SquarePants' game will launch on Roblox for the first time through a deal between Paramount and Gamefam.
