New for 2026 - the updated version of this extremely popular kit

You will be extremely proud to have built this excellent project.

There are 18 red LEDs, 18 blue LEDs, and one green LED around the outside of the 100mm diameter wheel which show the spin of the ball as it passes over the numbered pocket LEDs. The digital display in the middle also shows which pocket the ball is currently passing.

When you press the "Spin!" button, the ball-LED travels fast around the outside pockets then gradually slows down, eventually stopping on one of the pocket LEDs, and the digital display flashes to show your score  - watch the listing video!

Beautifully crafted and precisely engineered, this project is perfect for the more experienced electronics hobbyist.
