Apart from the Bingo Store, you will also be able to find some Pop-Up Offers, that can not be found in the store.
These offers will be either based on your in-game activity, or will appear when special events are active.
For example, Triple-Daub Offers, Special Events Currency (diamonds, dice), or Daub Alert Boost.
These promotions will be automatically sent to your account by the system, and some of them will only be available while the pop-up is active on your screen.
If you have mistakenly closed the pop-up, the offer will not be available anymore.
However, do not be disappointed, as Bingo Blitz will always find new promotions specially made for you!
