Résumé du livre

These puzzles will test solvers' powers of logic, reasoning, ingenuity, and wordplay. Flex your mental muscle with some of the toughest nuts to crack, including Geometracts, a visually vexing boggler, as well as Tic-Tac-Topology, a strategy game for two players. There are also lost, hidden, and missing-number conundrums that add up to loads of brain-stretching fun.
