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!

Customer Reviews (4.8 / 5 · 5 reviews)

Robert F. ★★★★★

My 9-year-old and I spent an entire evening working through the marble ramps and crossovers — it's surprisingly addictive for both kids and adults.

Evelyn ★★★★★

The bit and gear bit pieces finally made the "computer" concept click for me — watching a marble flip a bit and change the path is oddly satisfying. I bought it for my nephew but ended up staying up late finishing the later puzzles myself.

Charlotte F. ★★★★★

My 10-year-old and I spent a rainy Sunday on the first few puzzles, and watching her figure out how the interceptor catches marbles mid-drop was genuinely fun. The bits flipping back and forth make the logic feel physical instead of abstract.
