JIGSAWS

Jigsaw puzzles got their start in 18th-century England as an educational tool to teach geography. Mapmakers pasted maps onto wood and cut them into small pieces.

The use of popular pictures for jigsaw puzzles began in the 1860s, and the puzzles grew in popularity in the early 1900s.

The part that sticks out of a puzzle piece is called the "nub," which fits into a "void" in another piece to create a "lock."
