There is a base layer with a further four rings on top which rotate. There are a lot of possible combinations for this to sit at but only one solution.
This is made from alder with the numbers laser engraved an

Too easy for its rating
Got this for my dad who solved it in 5 minutes every time we reset it - so disappointing when you buy someone a puzzle / code cracker, you expect it to take a day or so. It took me minutes to solve too and I’m not as clever as my father. Wouldn’t have purchased it if I knew it was so easy. Beautifully made however but not worth the money.
