One of the earliest known brain teaser enthusiasts was the Greek mathematician Archimedes. He devised mathematical problems for his contemporaries to solve...

More about puzzle games
A puzzle is a game, problem, or toy that tests a person's ingenuity or knowledge. In a puzzle, the solver is expected to put pieces together in a logical way, in order to arrive at the correct solution of the puzzle. There are different genres of puzzles, such as crossword puzzles, word-search puzzles, number puzzles, or logic puzzles.
Puzzles are often created to be a form of entertainment but they can also arise from serious mathematical or logistical problems. In such cases, their solution may be a significant contribution to mathematical research.
Puzzles can be divided into categories. For example, a maze is a type of tour puzzle. Some other categories are construction puzzles, stick puzzles, tiling puzzles, transport puzzles, disentanglement puzzles, lock puzzles, folding puzzles, combination puzzles, and mechanical puzzles.
Puzzle Games Examples:
A chess problem is a puzzle that uses chess pieces on a chess board. Examples are the knight's tour and the eight queens puzzle.
Lateral thinking puzzles, also called "situation puzzles"
Mathematical puzzles include the missing square puzzle and many impossible puzzles — puzzles which have no solution, such as the Seven Bridges of Königsberg, the three cups problem, and three utilities problem
Mechanical puzzles such as the Rubik's Cube and Soma cube
Metapuzzles are puzzles which unite elements of other puzzles.
Paper-and-pencil puzzles such as Uncle Art's Funland, connect the dots, and nonograms
