Pattern Folding (officially 3D Form Development) shows a flat pattern and four 3D figures. You pick the figure the pattern folds into.

PAT Grind has 1,200 pattern folding questions at three difficulty levels. Each one is checked by an independent solver and comes with a step-by-step explanation.

How the questions work

  • The pattern is printed on the outside of the figure.
  • Exactly one of the four figures can be made from the pattern.

Strategy

  • Find the pairs of opposite faces first. Two faces that end up opposite can never be seen together, which rules out options fast.
  • Check direction: an arrow or an asymmetric shading has to point the right way relative to its neighbours.
  • Pick one corner of a figure and trace the three faces that meet there around the pattern, checking that they appear in the right order.

Common traps

  • Opposite faces shown side by side.
  • A marking turned 90 degrees.
  • The right three faces in mirror-image order.

PAT Grind's pattern folding questions use cube patterns. The real test also includes other shapes such as prisms and pyramids, but the same opposite-face and orientation checks apply.
