The modern puzzle finds its roots in the earliest recorded human history. Ancient civilizations created complex labyrinths and mazes. Personalized puzzle boxes or secret compartment jewelry prevented prying eyes from expensive goods. In the 1760s, European map makers pasted maps onto pieces of wood and cut them into small pieces. Since then, puzzles have continued to evolve, expand, and reach new difficulty levels, from dizzying puzzle balls to elaborate 3D wooden puzzles.
