The QiYi 4-Cube Pack Non-NxN Stickerless brings together four puzzles in a single box that step outside the standard cubic format: Megaminx, Skewb, Mastermorphix and Pyraminx. This approach answers a common need among cubers who have gone past the initial 3x3 stage and want to expand their collection to alternative formats without buying each puzzle separately, taking advantage of the joint pack price.

The Megaminx is a regular dodecahedron with twelve pentagonal faces, one of the official WCA events with the largest visual volume in the catalogue. Its solve follows a layer-by-layer logic analogous to the 3x3, though adapted to pentagonal geometry and a considerably larger number of pieces. The Skewb, also a WCA event, is solved through diagonal turns around the four axes crossing its corners, with a very different mechanic from the standard 3x3 that is surprisingly accessible once understood.

The Mastermorphix is a shape-changing variant based on the 3x3, but with a tetrahedral shell. When its layers turn, the pieces rotate and modify the puzzle's external geometry, generating visually surprising intermediate states. Although the internal mechanic is that of a 3x3, the reassignment of which pieces act as corners, edges and centres adds a conceptual layer of difficulty that sets it apart from the original cube. The Pyraminx, for its part, is a three-layer-per-axis tetrahedron and also part of the WCA catalogue.

All puzzles in the pack use a stickerless finish, with mass-coloured plastics that don't peel or wear with use. The QiYi brand keeps a consistent quality standard across its catalogue, and this kind of pack is especially useful as a gift or as a way to access several formats with a lower outlay than buying each one individually. It's a practical gateway to the world of non-cubic puzzles. The full pack offers a saving compared to buying each model separately and provides enough variety to explore different solving mechanics in the same session.
