List of products by manufacturer Calvins Puzzle

The Calvins Puzzle brand (originally Calvin's Puzzle) is run by Calvin Fan from Hong Kong. The manufacturer doesn't compete with GAN or MoYu in speedcubing. Instead, it makes puzzles outside of WCA events: shape mods, cuboids, bandaged cubes and unusual shapes. Many of these models aren't offered by any other manufacturer, which is why the Calvin's name shows up so often in twisty puzzle collections.

Calvins Puzzle – designs by well-known creators in mass production

A large part of the catalogue consists of designs by independent creators that, without mass production, would probably exist only as one-off pieces. Calvin works with Tony Fisher, Evgeniy Grigoriev, Traiphum Prungtaengkit and Japanese designers from the Okamoto family, among others. That's why many product names include the designers' names: Traiphum Megaminx Ball, Evgeniy Icosahedron, Fisher Wall Cube II, Okamoto Latch Cube, or the 3x3x5 Cross-Cube with Tony Fisher's and Evgeniy's logo. The collaboration with Evgeniy goes back to at least 2012, when a pillow-shaped version of the Dino Cube was released.

Key series and models

• Double Cube – the 3x3 Double Cube I, II and III series, plus the Mirror Double Cube with silver stickers.


• Cuboids – including the TomZ 4x4x6 Cuboid and the 3x3x5 Cross-Cube.


• World map cubes – Standard World Map and Flag World Map in 3x3 and 4x4 versions. Instead of solid colours, they feature a picture, so when solving you also need to keep track of center orientation.


• Minxes and other shapes – Double Megaminx, Traiphum Megaminx Ball (6- and 12-colour versions), Evgeniy Icosahedron, Time Wheel Pyraminx with Roman numerals, Bai-Niao-Chao-Feng Twist-Minx Cube.


• Crazy models – Full Function Crazy 3x3x3 and Full Function Crazy Tetrahedron in Center-Locking versions.


• Restricted-move puzzles – the Okamoto Latch Cube looks like an ordinary 3x3, but arrows and latches on the faces let some faces turn in one direction only.

Many models come in several versions: with stickers, stickerless or in metallic colours, and some are released as limited editions.

Who are Calvins Puzzle cubes for?

This range is mainly for collectors and cubers who can already solve a 3x3 and are looking for a new challenge. Calvin's cubes aren't made for breaking records. What matters is their unusual mechanism and the process of finding the solution, not TPS. Some models need to be lubed and broken in before they turn smoothly. The easiest place to start is the world map cubes, as they work like a classic 3x3 or 4x4. Bandaged puzzles, cuboids and the Okamoto Latch Cube are best left for later. As a gift for a child, the brand is a good choice once the child can already solve a regular cube.
