QiYi Pyraminx Keychain

QiYi Pyraminx Keychain

QiYi Pyraminx Keychain is a small, fully functional Pyraminx with a metal chain and a hanger. You can clip it to your keys, backpack or pencil case. It works just like a regular Pyraminx: you turn the tips and layers, scramble it and solve it with the same algorithms as a full-size model. The difference is in the size and purpose.

A mini Pyraminx for your pocket

The keychain measures approx. 37.5 mm, so it is noticeably smaller than a standard speedcubing Pyraminx. It fits in your pocket, so you can always have it with you. The chain is detachable, leaving you with just the miniature puzzle, which you can put on your desk or add to your collection.

The puzzle is stickerless, which means it is made of coloured plastic instead of having stickers. The colours won't peel off or wear away, even if you often carry it in your pocket or on your keys.

How it turns

The mechanism is simple, with no magnets. According to user reviews, it turns like a classic older-style Pyraminx, without a system that helps align the layers. The smaller pieces are also harder to move with your fingers, so during fast turning you will have less control than with a full-size model. The puzzle has screw adjustment, so you can tighten a looser unit a little.

If you want to practise Pyraminx for time, it's better to buy a full-size magnetic model. The keychain is great when you want to fidget in your free time, review algorithms while travelling or have a gadget related to your hobby.

Who is it for?

For cubers who already have a Pyraminx and want a keychain version of it, and for collectors of small puzzles. It's also a nice little gift for a child or teenager who is just starting out with cubes. A Pyraminx is easier to solve than a 3x3 cube, so many people learn it as one of their first puzzles.
