Professional 5x5, 6x6, and 7x7 Speed Cube Buying Guide

As a puzzle enthusiast, you've likely spent hours mastering 3x3 and 4x4 cubes. The algorithms hold no more secrets for you, and your times are improving daily. The question then becomes: what's your next challenge? Moving up to a larger professional speed cube—5x5, 6x6, or even 7x7—is the logical next step to push your limits.

But be warned: the more complex the cube, the more crucial your choice of model becomes. A faulty internal mechanism means lock-ups (locks) and frustration, enough to ruin the entire solving experience. This guide is here to help you find the advanced puzzle cube that is not only a worthy challenge but also a high-performance and enjoyable partner for both intensive practice and competition cubing.

Buying Guide for Your Next Advanced Puzzle Cube

Before diving into our selection, let's review the essential criteria for finding the perfect expert-level puzzle cube for you.

The Scale of the Challenge: 5x5, 6x6, or 7x7?

The transition to higher-order cubes is usually done in stages.

• The 5x5 cube (Professor's cube 5x5): This is often the gateway to more complex cubes. It introduces new algorithms for centres and edges while retaining an odd-layered structure, which some cubers find more intuitive than even-layered cubes.
• **The speed cube 6x6: This presents a different kind of challenge. As an even-layered cube, it introduces parity cases not found in odd-layered cubes (5x5, 7x7), forcing you to learn new algorithms.
• **The cube 7x7: Considered by many to be the holy grail of standard competition cubes, it combines insane mechanical complexity with a demand for extreme endurance and concentration.

Internal Mechanism and Smoothness

On a professional speed cube, the quality of the internal mechanism is non-negotiable. A good higher-order cube must offer smooth turning on all layers, not just the outer ones. Prioritise models with anti-lock and anti-pop (when a piece ejects) mechanisms. Excellent structural stability is also essential to handle fast turns without the cube deforming—a critical point for a competition cube.

Stickered vs. Stickerless

The choice between a stickered model and a stickerless cube is primarily a matter of personal preference.

• Stickerless Models: The pieces are molded directly from coloured plastic. The main advantage is durability: say goodbye to fading colours and peeling or chipping stickers. This is the premium option for heavy use.
• Stickered Models: These offer a classic aesthetic and a feel that some cubers prefer. The quality of the stickers is therefore crucial: opt for thin, durable stickers.

Frequently Asked Questions About Professional Speed Cubes

How do I maintain a professional speed cube?

Maintenance is simple but essential. A wipe with a soft, dry cloth is enough to remove dust. Most importantly, no liquid cleaners! To maintain perfect turning, a few drops of specialty speed cube lubricant applied periodically to the core of the mechanism will work wonders. Finally, store it in a safe place to protect its precision mechanics.

What is the difference between a 5x5 and a 6x6 cube in terms of solving?

The fundamental difference is parity. Odd-layered cubes (3x3, 5x5, 7x7) have fixed centre pieces that serve as reference points. Even-layered cubes (4x4, 6x6) do not. This can create "parity errors" at the end of a solve, which require specific algorithms to fix. The 6x6 therefore adds this extra layer of difficulty to the already high complexity of grouping centres and edges.

Are stickerless cubes allowed in competition?

Absolutely. In nearly all official competitions governed by the World Cube Association (WCA), stickerless models are permitted. The only condition is that each face must be a single, easily distinguishable colour. In fact, they have become the preferred choice for many competitors due to their durability and excellent recognition.
