About this game

Challenge your spatial reasoning with colorful 3D cube puzzles built around
mental rotation, geometry, and visual logic. Rotation Game makes brain
training easy to fit into your day, with quick challenges and 10 distinct ways
to practice.

Rotate, project, and think in 3D

Picture each move before it happens. Match rotated shapes, connect 3D objects
to their 2D projections, identify viewpoints, compare cube structures, and
work out how flat nets fold. Every puzzle asks you to see shapes from a new
angle.

10 spatial puzzle modes

• Rotation: follow the turns and find the matching shape
• Projection: match a 3D shape to its 2D view
• Viewpoint: choose the shape seen from a marked corner
• Same Shape: decide whether two forms match
• Missing Shape: find the piece that completes a structure
• Assembly: combine pieces to build the target
• Forming: turn front, right, and top views into a 3D form
• Cross Section: picture the result of slicing a shape
• Memory: remember a cube structure, then spot the match
• Net Folding: predict the 3D result of a flat net
