Big Brain

Think you've got a big brain? Prove it. Big Brain is 100 levels of tricks, riddles and logic puzzles. It starts out silly and ends up seriously hard. The answer is rarely where you first look, and the obvious move is usually the wrong one. OUTSMART THE TRICKS Poke, drag and tap everything on screen. Pop balloons that hide where you least expect them, put the brain to bed, and find answers hiding in plain sight. Some levels use your phone itself, so you might need to tilt it, shake it or plug it in. THEN IT GETS HARD Later levels are proper brain workouts. Catch the liar, crack codes, escape sliding block puzzles and work through Sudoku, picture logic, bridges, loops, a magic hexagon and more. OUTPLAY THE BRAIN Take on opponents that really play to win, including a game of hangman where the word keeps changing to dodge you. THE LAST EXAM Level 100 asks five questions. One slip sends you back to the start.
