One week after launching for iOS and Android devices, developer Playstudios’ free casino game, myVegas Slots, is already topping charts. It’s the top free casino app on iTunes, and it’s eight in the overall free games category. On the list of best-grossing casino apps, myVegas slots is ninth.

“To see our mobile app doing so well, so quickly, further validates the value proposition of our myVegas game — play free slots and win real rewards from an amazing collection of brand partners,” said Andrew Pascal, a founder and chief executive officer of PlayStudios, in a press release sent to GamesBeat.

MyVegas Slots is free-to-play but offers real, Las Vegas-themed prizes from casinos and restaurants such as the Bellagio, MGM Grand, and Wolfgang Puck.
