Microsoft Bingo is now available for Windows Phone as a universal app. Bingo was released earlier this year for Windows 8. It's a travel themed game that puts you in a number of interesting locations. And yes, it's compatible with 512MB devices.
Locations include the Great Barrier Reef, Paris, and more. As you play, win, and move around in the game, you'll earn Flight Points, which help you level up and unlock new locations. Each locale has a number of souvenirs to get, which will earn you special awards when you build your collection. You'll also be able to get special rewards from the Luggage as you continue to win.
Bingo lets you work with the community to reach a shared goal. Placing bets on specific numbers on the Power Card before matches will set you up for a chance to win Power Bingo. With each Power Bingo awarded, the community gets closer to reaching their common weekly goal, and you get special rewards for helping out.
