Build mechanical computers powered by marbles to solve logic problems.


With Turing Tumble, students can build mechanical computers powered by marbles to solve logic problems. It's a mesmerizing opportunity to "peek under the hood" and discover how computers work. It is hands-on, fun, easy to learn, and suitable for anyone age 8 and above. Best of all, the logic is all right there in plain sight - no coding syntax, smart phones or tablets required! Perfect for learning engineering and computer science concepts.

Turing Tumble comes with a board, marbles, 61 repositionable gears and switches, and a full-color 100+ page comic book that weaves 60 clever puzzles into an illustrated story about a space engineer stranded on a desolate planet. We find that kids ages 8-12 are able to get through the first 20-30 puzzles. Adults get addicted by puzzle 27, and their minds are blown by puzzle 35. Younger kids enjoy the first 10 and building their own computers.

"Turing Tumble has actually made me a better is challenging, rewarding...and just really, really fun. I cannot recommend it highly enough. It is the most ingenious, creative, clever puzzle I've ever seen." - Stephen Hall, game reviewer.

Directs balls in one direction, either to the left or to the right.

Lets ball paths cross over one another. Balls come in one side and exit on the opposite side.

The bit adds logic. It stores information by pointing to the right or to the left, like a 1 or 0.

When the computer's objective is complete, the interceptor is used to stop the computer from releasing any more balls.

Gears and Gear Bits
The gear bits are mind-bending, but they add a whole new level of functionality. They also make the computer Turing-complete, which means that if the board were big enough, it could do anything a regular computer can do (in theory!).

I bought Turing Tumbles for my eight grandchildren, ages 4 through 14. It has successfully engaged all of them. The older ones enjoy the change of solving the puzzles, while the youngest love watching the marbles over and over. My seven-year-old grandson was so proud of himself for solving a challenging puzzle that he was jumping up and down, shaking his clutched fists! This is a game that will definitely grow with the children.

I have been using Turing Tumble in my STREAM classes. The students are addicted!! They video their final product to me as proof of completion. They want to just keep doing another challenge and during free time ask if they can get them out. I bought one myself and the school purchased two. Three is not enough!!

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.

Suggested Science Idea(s)


Students can use the Turning Tumble to simulate computer coding to solve problems. Moveable gears, switches and balls affixed to the board allow students to engineer and use reason for a desired outcome. The process engages learners to develop and test clever solutions to the prescribed problems in the set. Turning Tumbles provides concrete experiences of how a computer behaves.
