The forty-eight diabolical Gardner puzzles collected in this deck have rewardingly offbeat setups, featuring learned professors who gallop up down-moving escalators, rose-red cities as old as time itself, and the walking habits of Immanuel Kant.
The sharpest puzzle purveyor working in the English language, the great Martin Gardner wrote his Mathematical Games column for Scientific American in 1956. The forty-eight diabolical Gardner puzzles collected in this deck have rewardingly offbeat setups, featuring learned professors who gallop up down-moving escalators, rose-red cities as old as time itself, and the walking habits of Immanuel Kant. The run really comes in, however, with the demands they make on the would-be solver's powers of reason and the exquisite simplicity of their eventual answers.
