Turing Tumble is a new type of game where players (ages 8 to adult) build mechanical computers powered by marbles to solve logic puzzles. Use ramps, crossovers, bits, interceptors, gears, and gear bits to build marble-powered computers that can generate patterns, do logic, count, add, subtract, multiply, divide, and much, much more.
This is the standard Turing Tumble kit, which includes everything you'll need to start building computers (no batteries required):
8 Gear bits
Puzzle/comic book with 60 puzzles
20 Red marbles
20 Blue marbles
