Brain Busters! Mind-Stretching Puzzles in Math and Logic

Puzzle lovers of every persuasion, prepare to be mystified and wondrously maddened! These 51 original puzzles by Barry Clarke, puzzle columnist for the London-based Daily Telegraph, present challenges ranging from moderate to difficult and span a terrific range of clever conundrums: word puzzles, complex crosswords, and math and logic puzzles.
The first section, Popular Puzzles, calls for a moderate amount of effort and imagination. It features complex crosswords in which cryptic clues must be solved in sequence and the solutions fitted together on a grid. Teaser Tales, the following section, contains longer puzzles in the form of amusing stories with a series of clues that must be solved to provide a single solution at the end.
The final section represents the Mount Everest of the collection, the Advanced Puzzles. Designed to stretch the mental muscles, these puzzles are more mathematical than their predecessors, but even the most difficult ones require no greater knowledge than high school algebra. Most of the puzzles include hints, and solutions are provided for all (no peeking!).
