I have created a macro that essentially auto-daubs all of your cards, and it even allows you to play 8 cards at once (and once I get to a high enough level I will also make one for 12 cards)
Playing more cards at once means you get more out of your tickets and power-ups and you spend less time playing, hence leveling up faster.
Here is the forum about the macro: Macro for automating Bingo games (download)
Instructions below (this is just a copy/paste from the original forum post that's why it has an introduction and all):
I'm currently in the works of a macro for automating Microsoft Bingo so you can play 8 cards at once and daub every single tile with ease (you'll still have to call the bingos yourself though, so you can't just leave it there). Once I get to a high enough level I'll upgrade it to 12 cards.
This will only work if your screen resolution is 1920x1080. You can check your screen resolution by right clicking the desktop, then clicking "Screen Resolution".
Even then it might not work.
You'll have to download AutoHotkey:http://www.autohotkey.com/
I'll update this forum when the macro is finished.Edit: I finished the macro tonight (Oct. 5, 2015). There are two versions currently, one for 8 cards and one for 4 cards. Once I reach a high enough level I will make one for 12 cards. Follow the instructions below for easy bingo game automation.
1. Check to make sure your screen resolution is 1920x1080 and download AutoHotkey using the information listed above. If your screen resolution isn't 1920x1080 and you can't change it to 1920x1080, I'm sorry I can't help you.
2. Once you've downloaded and set up AutoHotkey, right click on your desktop, hover over "New" and click "AutoHotkey Script". This should create a link on your desktop. Name it whatever you'd like (I named mine Microsoft Bingo Macro.ahk) but make sure you put .ahk after your name.
3. Now right click the link you've just created, and click edit script. Delete any text that is in there, and copy/paste the text enclosed in the spoiler into your AutoHotkey Script (you can get rid of the extra line breaks though if you'd like):
Auto-Daub for 8 Cards:
Auto-Daub for 4 Cards:
4. Save the script. Exit the script. Now double click on it to run it. Launch Microsoft Bingo. Do a test run in France so in case it doesn't work you haven't wasted all of your tickets. When the game starts, if you are doing 8 cards make sure the scroll thing is all the way at the top. Then hit ctrl+B. It should start auto-daubing all of the cards for you. It will do this once. Press ctrl+B again for it to auto daub again. You will know if it is successful or not because it will be daubing the tiles if you are successful (duh!).
5. Enjoy free daubing!
VERY IMPORTANT NOTES:
--You still must call the bingos yourself.
--This works in any area, not just France.
--DO NOT. I REPEAT. DO NOT. Move the mouse while it is auto-daubing. If you do it could result in things happening that you wouldn't want such as. Using power ups on accident, paying coins to auto-daub the cards on accident (which I hope you never have to do again after this), calling bingos on cards that don't have bingos on them, clicking on ads, buying coins, keys, power ups, and tickets with real money (it could literally, click on the plus sign, bring you to the MS store, and confirm your purchase right then and there). You get my point. DO NOT MOVE THE MOUSE.
--If you have touchscreen, you tap the screen to call the bingos while it is auto-daubing and it will not affect the mouse, but do not hold on the screen. Only tap. Holding will affect the auto-daubing and could lead to affects stated above.
--It takes about 2 seconds per card to auto-daub, so about 8 seconds for 4 cards and about 16 seconds for 8 cards.
--After you start running the script, pressing ctrl+B anywhere will start this sequence of mouse movements, SO DON'T PRESS CTRL+B UNLESS YOU'RE PLAYING MS BINGO AND WOULD LIKE TO AUTO-DAUB.
--After you run the script, you can stop it by stopping the process through the task manager or simply restarting your computer.
So yeah, as long as you follow what I stated above, you should be fine, but nevertheless: Use at your own risk.
