Microsoft Bingo

If you're following my advice in the Roadmap, you should never be calling bingo until the 10-second countdown at the end of each game. Because of this, there is a decent chance you'll unlock this naturally during a random game. Four bingos on a single card is a lot though, so there's a high likelihood you'll need to buy some extra numbers at the end of a game to get to four bingos on a single card. You'll likely be doing this towards the end of your journey to level 46, but if you don't, the easiest and cheapest way to do it is to play a game on the first destination, and when the game ends, buy extra numbers until you have four bingos, then call them all at once.
