Spatial Reasoning
About PlayMemorize Spatial Reasoning
Spatial Reasoning is a multi-mode spatial intelligence trainer. Each round asks you to mentally transform a shape or object and pick the correct result from a set of options · no arithmetic, no language, pure spatial cognition.
Three sub-skills. Rotation · find which option is the same object rotated, not mirrored. Nets · match a flat unfolded net to the 3D solid it folds into. Shadows · given a 3D block stack and a light direction, identify the correct 2D shadow.
Why train spatial reasoning? Spatial sub-skills are among the cognitive abilities most responsive to practice. Mental rotation and net-folding ability correlate with performance in geometry, engineering, architecture, surgery, and any field that requires reasoning about objects in three dimensions.
Streak format. Each correct answer advances the streak; one wrong answer ends it. Difficulty increases the complexity of the shapes, the number of distractors, and the subtlety of the differences between options.

FAQ
Q: What is Spatial Reasoning?
A multi-mode spatial intelligence trainer. Each round asks you to mentally transform a shape · by rotating it, folding a flat net into a 3D solid, or tracing the shadow a block stack casts in a given light direction.
Q: What are the three modes?
Rotation (find the rotated match, not the mirror), Nets (match a 2D unfolded net to the 3D solid it folds into), and Shadows (given a block stack and light direction, pick the correct 2D shadow).
Q: How is this different from the existing Spatial game?
The existing Spatial game focuses on mental rotation of polyomino shapes. Spatial Reasoning adds two additional sub-skills · net-folding and shadow projection · in one place, covering a broader range of spatial cognition.
Q: Can spatial reasoning be trained?
Yes. Research consistently shows that short, regular spatial training improves performance on rotation, net-folding, and related tasks. The improvement transfers to real-world tasks that require reasoning about 3D space.
