Brain Defense support
Is Brain Defense free?
Yes. There are no ads and no in-app purchases.
Which account do I sign in with?
Your Braineos account, using Google. You can play your own decks or any public deck from Discover.
Why can’t I play a deck?
A deck needs at least four usable cards. Flashcards with very long answers are left out, because they don’t fit as answer buttons.
How do I unlock the other levels?
Clear a level with a deck to unlock the next one for that deck. There are three levels: The Straight Path, The U-Turn and The Spiral.
Where are my best scores saved?
Your best wave for each deck and level is saved on your phone.
Is there an iPhone app?
Not yet. Brain Defense is Android only for now.
Where can I find the privacy policy?
