by Dear Librarian
The Big Book of Brain Games is big! It’s got 1000 brainthinks within it over 420 pages. The puzzles are specific to art, science, or math. The puzzles are marked by their difficulty, so you can mark your progression. All the puzzles are super colorful, and the answer key in the back is very explanatory. This is a very, very fun book that could keep you entertained for hours!
