Definition
Pieces form a picture, model or three-dimensional object by matching boundaries, tabs, slots or visual information.
How to recognise this family
Look first at the objective and permitted movements, not only the outward shape. Typical examples include traditional jigsaws, wooden construction models and sheet-metal models.
- What must the solver achieve?
- Are the pieces separate, interlocked or permanently connected?
- Does the challenge depend on an ordered sequence, physical dexterity or discovering a hidden release?
Common solving approaches
Establish the rules, inventory the pieces and record every state-changing move. Search for constrained components, repeated patterns, symmetry and actions that create additional freedom. Stop if force appears necessary.
