Available on Facebook since July of 2010, so far Bingo by Ryzing has shown the slow growth that most other bingo games have on the platform, with the game's monthly active users peaking this month at 250,000 according to AppData traffic tracking service. What sets Bingo by Ryzing apart from the other bingo games on the platform are the game's real world prizes, which are awarded via a sweepstakes method to skirt Facebook's restrictions around cash payouts.

"Facebook doesn't allow gambling and Bingo by Ryzing does not incorporate gambling as there is no purchase required and purchasing does not improve a player's chances of winning," explains Ryzing's CEO Manu Gambir when asked about the game's prizes.  "Bingo by Ryzing is a sweepstakes exactly like other sweepstakes you may be familiar with, such as the popular McDonald's Monopoly sweepstakes."

According to Gambir, Bingo by Ryzing uses multiple types of bingo cards, only some of which allow players to win prizes, which can be either cash, merchandise or gift cards.

"The first, and primary type of bingo game, is played using blue-colored bingo cards. Players purchase these bingo cards using virtual currency which can be obtained for free (by playing often, completing achievements, inviting friends, or watching videos) or by purchasing," he says.

Bingo by Ryzing is RockYou's first foray back into publishing since confirming it would be laying off more than half of its staff, selling Playdemic back to its founders and parting ways with Loot Drop in November.
