Microsoft Bingo

While this achievement is technically luck-based, you should be playing enough bingo games to get to level 46 that this will unlock naturally. Personally, I unlocked this achievement around the time I was level 15. The more cards you play per game, the more likely you are to get bingo with four corners. However, if you follow the strategy for leveling up in the "Around the Globe" achievement solution, you should definitely unlock this along the way.

Additionally, a surefire way to get this is to wait until you unlock later destinations and have a lot of money saved up, then play bingo games on the first destination with 1-4 cards. Then, if you don't get any corner bingos, spend coins to have more numbers called. Extra numbers are very cheap in the first destination, especially after you've saved up from later destinations.

This achievement requires that you call Bingo on the corners of a card a cumulative total of 20 times across all of your cards in all of your games. Bingo corners is a slightly less obvious type of Bingo. You must daub all 4 corner numbers on a card, then call Bingo to count towards this achievement. This will come in time, far before unlocking most of the other achievements. The key to this one is making sure to recognize this Bingo and call it when you get it.
