Jack Krijnen’s highly sought after Merry Go Round puzzle set. One of my favorite N-Ary puzzle because there are so many N-Ary configurations. You can solve this as a nice and relaxing binary puzzle or you can make it more challenging and solve it as a ternary or even harder, quarternary or above and beyond with the Quinary. You can also mix and match and come up with your own N-Ary configuration from easy to challenging. All in all, solving any will bring a big smile to your face and a great sense of accomplishment. This is one of the most expanded N-Ary set out there and comes in excellent condition.
