How it works
Battle of the Books is two question formats. We drill both. Two study modes. Five mastery levels. One account that follows your reader across devices.
Two question types
In What Book
A scenario, quote, or plot detail is presented. The reader picks which book it comes from.
Example
In what book do magpies outside a window sound just like R2-D2?
→ Bob by Stead
Book Trivia
A specific book is named in the question. The reader recalls a detail like a character, plot point, or fact.
Example
In Holes, what was the nickname of the boy who had Stanley's cot before him?
→ Barf Bag
Two study modes
Multiple Choice
Pick one of four answers. Immediate feedback with the correct answer and a brief explanation. Sticker drops when you earn one.

Flashcards
Tap to flip. Mark “Knew it” or “Didn't know it.” Mastery per card builds over the deck.
- Shuffle on or off
- Optional review of mastered cards

Five mastery levels
Track per-book mastery as accuracy and coverage build over time.
