About PlayMemorize Spatial

PlayMemorize Spatial is a free mental rotation game. You see a reference shape (a polyomino) and must identify which of the answer options is a rotation of it, not a mirror image. This trains spatial reasoning, one of the core components of fluid intelligence.

Progressive complexity. Easy mode starts with 3-cell shapes in a single color; Medium starts at 4 cells and Hard at 5. As your streak grows, shapes grow up to 7 cells and gain up to three colors that follow their cells through rotation, adding another dimension to track. You choose how many answer options to face (from 2 up to 10).

Carefully crafted distractors. Wrong answers are primarily mirror reflections of the reference shape, rotated to various angles. When more options are requested, slightly modified shapes (a single cell moved by one step) and other asymmetric shapes are added. This forces true mental rotation rather than elimination by visual dissimilarity.

Part of the PlayMemorize family of free memory and brain training games.

Часто задаваемые вопросы

Q: What is mental rotation?

Mental rotation is the ability to imagine how an object looks when rotated in space. It is a core spatial reasoning skill tested in IQ assessments and strongly associated with success in STEM fields.

Q: Is the Spatial game free?

Yes, completely free. No account, no ads. Your high score is saved locally in your browser.

Q: How does difficulty increase?

Shape complexity grows up to 7 cells (Easy starts at 3, Medium at 4, Hard at 5). Colors increase from 1 to 3 on Medium and Hard, and colors must be tracked through rotation. You pick the number of answer options yourself (2, 4, 6, 8, or 10). All generated shapes are guaranteed to be asymmetric, so a mirror image can never coincide with any rotation of the original.

Q: What makes the distractors challenging?

The primary distractors are mirror reflections of the reference shape, rotated to various angles. Since mirrors look very similar to rotations, you must perform true mental rotation to distinguish them rather than spot a superficial difference.
