The Rubik’s Cube is one of the most famous and iconic puzzles in the world, challenging minds since its creation. However, many people vividly remember it being called the “Rubix Cube” instead of “Rubik’s Cube.” This discrepancy has led to yet another fascinating Mandela Effect—where a large group of people recall something incorrectly but with absolute certainty.
Memory vs. Reality: “Rubix” or “Rubik’s”?
- The Memory: Many people distinctly remember the puzzle being called “Rubix Cube”, with an “X” at the end.
- The Reality: The correct name has always been “Rubik’s Cube,” named after its inventor, Ernő Rubik.
Why Is It Called “Rubik’s Cube”?

The cube was invented in 1974 by Hungarian architect and professor Ernő Rubik. Originally, he designed it as a teaching tool to help students understand three-dimensional spaces. The puzzle was later mass-produced and became a global sensation. Since it was created by Ernő Rubik, the correct name has always been “Rubik’s Cube”—with an apostrophe to show possession.
I didn't think a Mandela Effect could fuck me up more than the chartreuse one but the Rubix cube one is actually insane

Why Do So Many People Remember “Rubix Cube”?
There are several possible explanations for this widespread false memory:
1. The “X” Sound Feels More Natural
“Rubix” flows off the tongue more smoothly, and the “X” sound makes it feel like a brand name—similar to words like “Kleenex” or “FedEx.” Many assume “Rubix” was the intended spelling, even though it never was.
2. The Logo’s Design May Have Caused Confusion
Some versions of the Rubik’s Cube logo feature a stylized font that could make the “k’s” look like an “x” at a quick glance, possibly reinforcing the “Rubix” misinterpretation.
3. The Mandela Effect at Work
The Mandela Effect describes instances where a large number of people collectively misremember something, and “Rubix Cube” is one of the most commonly cited examples. It’s similar to how people remember “Berenstein Bears” instead of “Berenstain Bears” or “Febreeze” instead of “Febreze.”
