Brain Test Answers: Levels 51-100
Levels 51 to 100 are where Brain Test gets genuinely sneaky: riddles like level 62, physics tricks like the frog at level 64 and level 70's borrowed digits, and interface lies like level 90's stubborn lamp. Every level in this range has its own card below, including the heavily searched 79, 83, 85 through 91, 93, 95, 98, 99 and 100. Tap a card to reveal just that answer.
