## What is 3D Reflection Challenge?

Study the shape, remember its position, and rebuild its reflected form.

This visual 3D challenge tests your observation, memory, and spatial reasoning.

Study the blue reference, then move and rotate the red pieces into their correct reflected positions. Challenges expand beyond simple left-to-right symmetry to include front-to-back, diagonal, vertical, and cross-axis transformations.

FEATURES

• 100 handcrafted and progressively challenging stages
• Random Mode with newly generated layouts
• Multiple reflection axes and board shapes
• 3D rotation, orientation, height, and stacking challenges
• L-shaped, S-shaped, diamond, and cross-shaped boards
• Simple controls designed for short play sessions
• Normal stages can be played offline
• Two introductory stages that teach the core mechanics

Later stages introduce letters, arrows, marked surfaces, complex silhouettes, and puzzles where the board itself must be rotated.

A piece may look close to the answer, but its direction, depth, or height can still be wrong. Observe carefully, think in three dimensions, and complete all 100 stages.
