Common Mistakes
- Spelling: 'Rubix Cube', 'Rubics Cube'.
- Omission of apostrophe: 'Rubiks Cube'.
- Using it as a verb incorrectly: 'I Rubik's Cubed it.' (non-standard).

FAQ
Frequently Asked Questions
In the formal trademark 'Rubik's Cube', yes. In informal use, especially when not referring specifically to the brand (e.g., 'a Rubik's-cube-style problem'), it is often lowercased.
Not formally. The standard verb is 'to solve a Rubik's Cube'. However, in the speedcubing community, the back-formed verb 'to cube' (meaning to practise or solve twisty puzzles) is widely accepted as jargon.
'Rubik's Cube' is the trademarked name for the specific puzzle invented by Ernő Rubik. 'Magic cube' is a generic term often used for similar twisty puzzles, especially in languages and contexts where the trademark is not enforced.
Both are correct depending on context. Use 'a Rubik's Cube' when referring to any one cube (e.g., 'He bought a Rubik's Cube'). Use 'the Rubik's Cube' when referring to the concept or a specific one (e.g., 'The Rubik's Cube was invented in 1974.', 'Pass me the Rubik's Cube on the shelf.').
