Now, however, it's hit an even bigger number with the news that over 200 million people are using the real world rewards service.
It says this is up from 100 million users only two months ago.
Real offers, real cash
Beintoo mixes traditional advertising models with virtual incentives so users are rewarded for their in-game activity such as posting score to leaderboard and winning challenges, as well as when interacting with adverts and other offers.
A big draw are the direct offers. A current one sees you get a $10 Papa John's gift card when you sign up for Netflix's free month trial, while other offers uses the in-platform Bedollars currency.
Neatly, you can now cash this out by redeeming through PayPal; no doubt one reason Beintoo is seeing a surge in interest.
