Roblox raised its annual bookings forecast on Thursday and topped 100 million in daily active users thanks to the viral success of farm simulation title "Grow a Garden", sending shares of the videogame platform rising more than 16%.

Roblox raised its full-year bookings forecast and crossed 100 million daily active users for the first time, driven by the explosive popularity of a new farm simulation game, Grow a Garden (your kids probably have told you about it).

Grow a Garden, created by a 16-year-old in a few days, has shattered records for the most concurrent players of any game in history, beating out video games that take years and millions of dollars to develop.
