Can your rotate the rings to get all 6 columns to add to 100 at the same time? Only 1 solution, but 5700 possible permutations of the wheel.
A very beautiful puzzle designed and precision made by CreativeCrafthouse in our Florida shop. The base measures 5" in diameter. The base is 1/4" thick and the rings 1/8" thick.
There are 2 versions available here. They differ only in the wood used. The standard model uses precision ground alder. The premium version has a maple base and maple top button. It gives a little more color contrast and makes the puzzle look at bit like a flower.
