How to Play

Look at the 3D block shape on the left. Then choose which option shows the same shape after rotation.

The correct answer may be turned around in space, but the block structure is unchanged. Distractors may be mirrored, missing a block, or have one block moved.

Controls

  • Click an option to answer.
  • Press 1-4 to choose an option.
  • Press N or Space for the next question.
  • Press R to reset your score.

Practice Tips

  • Focus on corners, branches, and how many blocks touch each block.
  • Try mentally turning the whole object before comparing details.
  • Watch for mirror images. They often look almost right but cannot be rotated into the target.

This game is useful preparation for geometry, diagrams, engineering drawing, and other tasks that ask students to imagine objects turning in 3D.
