Daub StamperG 15

Daub Stamper G15:
Daub 500 cells across multiple Bingo matches.

Comes naturally as you play. As your numbers get called out, just click (daub) the same number on your Bingo board.
Once you have clicked 500 across all your games this will pop.

If you have this on the Windows 8 version, this one will pop as soon as you start up the Windows Phone version.
