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. See how simple switches, connected together in clever ways, can do incredibly smart things. Discover how computers work!
