Caesars Interactive buys Bingo Blitz developer Buffalo Studios about a year after buying Slotomania developer Playtika.

While not surprising to see Caesars making another acquisition in the social/mobile games space given its long term commitment to being No. 1 in i-gaming, we are a bit surprised to see the casino branch going with Buffalo Studios when lately Bash Gaming (formerly BitRhymes) has been getting more media attention for its success with Bingo Bash on mobile.

The last we heard from Buffalo was in October, when the studio touted Facebook’s power of engagement, saying that 80 percent of Bingo Blitz’s mobile revenue came from Facebook players. In June, the developer partnered with Riviera Casino & Hotel for an in-game themed promotion, but that was the greatest extent to which we’d heard the developer was working with a land-based casino company.

UPDATE: A source with knowledge of the deal tells Inside Social Games that the base purchase price for Buffalo Studios was lower than what Caesars Interactive paid for Playtika. Like Playtika, the Buffalo acquisition also includes an earn-out amount based on future profit.

Terms of the acquisition were not disclosed. Caesars Interactive will retain 74 employees at Buffalo Studios’ Santa Monica studio and roll both Bingo Blitz and its game, Bingo Rush, into an affiliate of its Playtika subsidiary.

According to AppData, Bingo Blitz is currently the No. 6 most popular Facebook game in the Gambling category with 710,000 DAU, right behind Bingo Bash with 750,000 DAU. Zynga’s Texas HoldEm Poker is at the No. 1 spot with 6.5 million DAU, followed by Playtika’s Slotmania with 2 million DAU.
