Super Mario Run was among the notable announcements of Apple’s iPhone 7 launch event. The game based featuring the beloved Italian plumber has been part of the childhoods of most of today’s adults, and carries with it a heavy dose of nostalgia factor. Super Mario Run is now finally available on iPhone’s App Store

Super Mario Run is free to download, but you must pay £7.99 in the UK and $9.99 in the US to unlock everything it has to offer.

Research firm SuperData said in a note this week that it expects Super Mario Run to reach around 30 million downloads and bring in $60 million in its first month. The company noted that this is well below Pokemon Go, but that game was launched on iOS and Android simultaneously. The Android version of Super Mario Run is coming later, though a specific release date has not been announced.

It might be possible to play the game through an iOS emulator for Android. But it’s not likely to work well, involves downloading the game illegally, and it’s probably going to be better for it to wait for the Android release date.

Nintendo’s entrance to the mobile game market earlier this year has so far been successful. Its social media app “Miitomo” did well, while “Pokemon Go” –developed by Niantic, which Nintendo has a stake in – went viral. “Super Mario Run” was developed by Nintendo and DeNA however, which should help Nintendo see more of the revenue from the game.
