Microsoft Bingo

As the description says, you need to use a cumulative total of 200 power-ups across all bingo games. This achievement will easily unlock by the time you reach level 46 (I unlocked it around level 20) as long as you follow the leveling up method described in the "Around the Globe" achievement solution. Refer to it for more information on earning power-ups. As far as each power-up, what it does, and how to best utilize it, each one is described below. Definitely read up on this so you're familiar with them all and maximize their potential.

Lightning Bolt - this is a picture of a lightning bolt and it supercharges your power-up meter on the right, allowing it to fill up 3 times faster than normal. DO NOT use this power-up unless it is the first one that you get in a match, otherwise you're wasting its potential. If you use it first, it will allow you to use many more power-ups in a single match once it's activating, giving you many more benefits.

"B" Power-Up - this is a letter "B" and when you use it, it puts one star on each card you're playing. If you daub that tile that the star is on, it's an automatic bingo. Like many power-ups, you should try to use this one as early as possible in the game to maximize the possibility of daubing the tile(s) with stars on them.

Star Power-Up - this is a picture of a star, and don't confuse it with the B power-up above. Using this power-up automatically daubs 2 random tiles on each card. Because of this, this power-up should be used as late in the game as possible, otherwise you're potentially wasting it if those numbers that were daubed were called anyway. Wait until there are 1-2 bingos left and then quickly use this power-up.

Key - this is a picture of a key, and when used, puts 1-3 keys on the board on random tiles. Daubing a tile with a key gives you a free key. Use this one as early as possible.

Coin - this is a picture of a circle (a coin), and when used, puts 1-3 coins on each board on random tiles. Daubing a tile with a coin gives you free coins. Use this one as early as possible.

Luggage - this is a picture of a handbag, and when used, puts 1-3 luggage on each board on random tiles. Daubing a tile with a luggage gives you a free luggage to open. Use this one as early as possible.

Diamond - this is a picture of a diamond shadow. THIS IS THE MOST IMPORTANT POWER-UP IN THE GAME. I can't reinforce that enough. When used, this puts diamonds on each board, typically on 2 tiles per board. Daubing them gives you bonus experience. Daubing these tiles is, by far, the fastest way to level up. Use these as early as possible in a game to maximize the chance of daubing them, and use them as efficiently as possible.

X2 - this shows an "x2" on the power-up, and when used, doubles the amount of coins AND experience you earn in that game. It doubles both at the end, so it doesn't matter when in a game you use this power-up, as long as you use it before 30 bingos are called. This should optimally be coupled with the "Coin" and "Diamond" power-ups above to maximize coins and experience earned per game.

Crosshairs - this is a picture of 4 little arrows pointing to the center. When used, this power-up points out called numbers on your bingo cards. So, it's essentially useless unless you want to take a break from daubing tiles and then come back and daub all the marked ones. Use these as soon as they come up to get rid of them.

? Power-Up - this is a picture of a question mark. When used, it reveals the next 5 numbers to be called. At first, this may seem pointless because those numbers are going to be called anyway. Once you realize you can use this power-up to "cheat" though, it becomes very useful. To do this, you're going to save it until there are only 5 or so bingos left to be called. Then, use this power-up to reveal the next 5 numbers. Now quickly daub those numbers on your boards. This typically will allow you to get 3 or so more numbers than all other players before the game ends. You have to be fast though because this results in you daubing numbers during the 10 second countdown. Also don't forget to call bingo on every card.
