Burrs and crosses
Notched sticks form a locked core. Piece count alone does not identify the mechanism.

Interlocking wooden puzzles: burrs, crosses, cubes and balls
A guide to the main interlocking wooden puzzle families, how they differ, and how to identify the correct solution.
What makes a wooden puzzle interlocking?
An interlocking puzzle holds itself together because the pieces block one another. Removing or inserting the correct key piece changes which parts can move. This family includes classic burrs and many objects sold simply as a wooden cross, ball, star, cube or barrel.
Cubes
Some cubes are burr constructions; others are polycubes or connected chains such as Snake Cube.
Cube solutions →Balls and spheres
Curved pieces can conceal the same locking logic used in more angular interlocking puzzles.
Ball and sphere solutions →Stars and barrels
Decorative finished shapes often hide a burr-like central structure.
Star solutions → · Barrel solutions →How to identify an interlocking puzzle
Count separate pieces, note the finished shape, compare notch patterns and isolate the unusual piece. If the puzzle is assembled, photograph every face before taking it apart. The wooden puzzle assembly guide gives a repeatable workflow.
Difficulty is about mechanism, not just piece count
A six-piece burr can be harder than a twelve-piece decorative puzzle if its locking sequence is less obvious. Likewise, two 12-piece puzzles can have completely different movement constraints. Treat piece count as an identification clue rather than a difficulty rating.
