Mechanical computer using ball - serial logic

Not the way computers actually work, but Absolutely good logic puzzles, and problem solving is what most of life is about. Components are well made and the device has this market completely to itself.

I recommend this product

I got this for our 6 yr old son who loves math and logic problems. We saved it until Easter, and now we are all obsessed. It’s great to let our son play and test solutions or to do a problem all together.

I like it so muuuuch!!

So much fun! It's a great game of logic and creativity. The book, which is a comic with a cool story, allows you to discover lots of possibilities of assemblies. There are a lot of pieces to do whatever you want, so you can even invent new possibilities, endlessly. It makes you think, check if all works as expecte, if some arrangements are effective or not, can be improved. We never get tired of it. The sound of the marbles gives the impression that a machine is starting and coming to life.

Engaging and fun!

purchased for my 8 and 10 year old homeschooled sons. They were so excited to start and played with it constantly for a week. It still get a lot of traffic, and they like to make up their own patterns as well. My 8 year old loves marble runs so much, so this is amazing for him. I like watching them trouble shoot when it doesn't work the first try.

Best toy I've found for teaching kids about computers

I've tried a lot of different games that are intended to introduce kids to the principles of computing, and Turing Tumble is by far the best. It's the only one that actually "computes" on its own (without an actual computer being involved), and it's wonderful to see in action. The attention to detail in the design is amazing, and presenting the puzzles in the form of a manga story is brilliant. My daughters are hooked and I've had fun working through many of the puzzles myself.

Excellent Game

Bought this for my intelligent 7 year old nephew, I opened the box, read the instructions, assembled the board and solved the first puzzle using the example in the instructions. The puzzles ( if that’s what you want to call them) get more challenging as you move forward. I got to the next puzzle and was staring at it wondering what to do when my nephew walked in. I gave him the basic instructions and he started putting the pieces on the board without hesitating. I asked how he knew what he was doing and he says ( it will change directions here) and resumes. We pushed the lever and the correct pattern emerged. I had to contend with the fact that a 7 year old is smarter than me when it comes to this stuff. He went on to flip the pages and solve the ( puzzles) without thinking about it. What can I say? Some brains are just wired a certain way...

Best Toy Ever

My 8 and I0 year olds grandsons opened their birthday present, a Turing Tumble, during the week long freeze here in Texas. They loved each new challenge and worked together beautifully to solve the puzzles.

Great for adults and kids!

I’m a 69 year old grandmother who bought Turing Tumble for myself! I’ve shared it with grandkids and they love it too - plus they solve the challenges faster than I can.

My son hasn’t stopped playing with it!

I got this for my 10 year for his birthday and he’s completely enthralled. His engineer’s mind loves it!! On day 1 he got halfway through the book and then started making up his own challenges. It’s well made and the comic style challenges are fun. A second or third book would be a great idea. Only design suggestion for future is to make a small vertical lip at the bottom where the balls rest after they go through the maze. The balls fall off easily if it gets jostled accidentally.

Perfect for Budding Coder!

My son loves numbers and has only recently started enjoying coding- this product was a perfect jump for him! He loves marble races and logic puzzles and this has kept him engaged for hours. It has been a nice bonding experience with his dad and he has made lots of connections to how this can be applied in real life. Our first item was lost in the mail over the holidays- Turing Tumble sent us another, quickly, with no questions asked. Highly recommend!
