Whether it serves as a chill escape from the onslaught of the real world or simply a way to beat vacation doldrums, a viral Roblox game about gardening has become the surprise hit of the summer.

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.

And there’s no one to shoot, fight or race. If your last attempt at cultivating vegetables was FarmVille in 2010, don’t worry — your tomatoes will grow even if you never water them.

Grow a Garden is as simple as its name suggests — players can fill a plot of land with plants and animals, harvest and sell, trade or steal each others’ bounty. The game is low stress, with an aesthetic reminiscent of Minecraft and a soundtrack of soothing classical tunes such as Mozart’s Rondo Alla Turca playing in the background. Its popularity has further cemented Roblox’ place not just in the gaming world but in popular culture — for better or for worse, it’s where the kids hang out.

“The word I keep hearing used over and over to describe this particular game is that it’s chill, which is just such a nice alternative. I get a lot of sort of that Animal Crossing vibe from it. You know, like you can check in, you can check your gardens, you can get some new seeds, you can plant them,” said Betsy Bozdech, editorial director at the nonprofit Common Sense Media.

“I have an 11-year-old son who (plays it) and he says to him the big difference is that a lot of games have a big giant objective that you have to do, but in Grow a Garden, you can just kind of hang out and do what you want.”

Coincidence or not, Grow a Garden soared to popularity around the same time that Take-Two Interactive announced it would delay the launch of its wildly anticipated Grand Theft Auto 6 until next year. In late June, the gardening game logged 21.6 million concurrent players, surpassing Fortnite’s previous record of 15.2 million according to Roblox.

Analysts who follow Roblox’s stock say Grow a Garden is helping boost the company’s revenue and will push the company’s quarterly earnings numbers above Wall Street’s expectations.
