Marvel: Contest of Champions reached No. 1 on the iPhone top-grossing chart for the first time

Cyber Monday deals aren’t just for buying physical goods from Amazon. You can also get a decent deal on in-app purchases in certain mobile games — and that led to a spike in revenue for one of Kabam’s biggest apps.

Marvel: Contest of Champions, a simple fighting game for iOS and Android, was the top-grossing iPhone game on Monday, according to data from research firm Sensor Tower. This is the first time the game has hit No. 1 on that revenue chart, which means it made more money than Game of War, Clash Royale, or Pokémon Go on that one day. Contest of Champions has since dropped back down to No. 9 on the iPhone grossing chart, which suggests that it was the Cyber Monday discounts that got players spending.
