Brain Defense
A tower defense game powered by your flashcards.
Brain Defense is a tower defense game where the gold comes from answering questions. Pick one of your own Braineos decks, or one from Discover, then answer its questions to earn gold, with a bonus for answers in a row. Spend it on three kinds of tower to stop each wave of enemies. A question you miss comes back a few questions later.
It plays any deck with at least four usable cards. Multiple-choice cards are asked as written, and flashcards become four-option questions. There are three levels, The Straight Path, The U-Turn and The Spiral, with 10 waves each, and clearing a level with a deck unlocks the next one for that deck. Relaxed mode slows the action if you want more time to read.
