While investors might have their concerns about the money making potential of Super Mario Run which was released on the iOS App Store yesterday, it seems their fears might be unfounded as the title is currently the top grossing app is both the UK and US, and no doubt many other territories too.

In the UK we can see Super Mario Run in the no.1 spot, followed by Pokémon GO, Spotify, Candy Crush Saga and Tinder.

So far Super Mario Run is only in 5th place in Japan according to App Annie, but we expect it will shoot up the charts as the day progresses. While it is early days for Super Mario Run, it's looking very promising so far.
