Mental gymnastics for clever minds, and those who like to train them.
Brilliant inventors of games and puzzles, such as the famous American Sam Loyd (1841 – 1911) enjoyed wrapping these riddles in charming anecdotes and amusing stories, and often published them in magazines. Some of the stories have become world famous.
A challenge for your intellect and imagination, both exciting and fun. The appendix includes the solutions to the puzzles.
By Sam Loyd and Martin Gardner
