Stick puzzle
Stick puzzles are a type of combination puzzle that uses multiple sticks or 'polysticks' to assemble two- or three-dimensional configurations.
Polysticks are configurations of joined or unjoined thin 'sticks'. The sticks may be; line segments on paper, matchsticks, pieces of straw, wire or similar.
A special class of stick puzzles are 'matchstick puzzles', where all parts used are sticks rather than polysticks. Some trick puzzles can only be solved when one assumes that the sticks actually have measurements in more than one dimension. Three-dimensional arrangements like tetrastix can also be made from matchsticks.
