This is one of the oldest puzzles in the world, and it is still hard. Nine steel rings threaded onto a bar, and only one sequence of moves gets them off. Get it wrong and you are further from the answer than when you started.
What makes it last is that it resets. Solve it, put it back, hand it to someone else. There is no completed state to display and no reason to stop.
Why people buy it
