The Rubik's Cube is a fascinating toy. Since its invention, it's spawned clubs, speedrunning competitions, and many derivatives. However, it's not known for being an intuitive toy, and in a lot of cases, those encountering it for the first time may be taken aback by its design.
Occasionally, a character will discover the cube and fiddle around with it for a bit, perplexed by the mysteries of its multicolored faces. This usually occurs in settings that take place on alien worlds or After the End, where novelty is less important than survival or the person who finds it is of a different mindset. Sometimes this produces a childlike sense of wonder, while other times it results in frustration and obsession. Discovering the intended "use" doesn't always correct things — it may cause the individual to become even more determined to solve it, and then finding out nothing happens could be... upsetting.
Despite the name, for the trope to count, the character cannot simply be finding or playing with a puzzle cube toy, rather it's for seeing one for the first time and not understanding it. If the Rubik's cube is used to show how smart the character solving it is, then it's Rubik's Cube International Genius Symbol.
- In Overlord, Zesshi Zetsumei owns a Rubik's Cube, which is considered to be a divine artifact as it was brought into the New World by an YGGDRASIL player long ago. She fiddles with it often and comments that she can never seem to get more than one side solved.
- There's a Touhou Project fan 4koma (NSFW warning, it's Danbooru) that has this as the first plot arc.

- Stellaris: One of the anomalies you can discover is a box, its description being obviously a Rubik's cube.

- In Zeno Clash, the Golem has a Rubik's cube that he fiddles with throughout the game, finally solving it at the end.

- In an odd variation, on Gilligan's Planet (a sequel to the animated adaptation of Gilligan's Island) they find a "mysterious cube" on the planet. The Professor notices that if you get one side all one color, it sends off a ray that enlarges. A side of a different color emits a reducing ray. So, a Rubik's Cube that DOES something when solved.
