Nintendo's Ten Billion, released in 1980. It was released to compete with the Rubik's Cube at the time, and its high difficulty and over 10 billion possible combinations were its selling points. The transparent barrel is divided into sections, and you rearrange the round balls inside to match or not match the colors. You can get lost in it and forget the time. It's an analog game with that kind of charm. It was a product from 1980, and it also had a certain interior design element, and people were surprised by it, and those who saw it were very interested. There is some sun fading, but that's the taste of Showa retro! Fun for all ages, so please give it a try! MADE IN JAPAN SIZE Height 8.6cm Width 5.5cm Thank you for viewing.
