Slitherlink 2 - Gareth Moore - Bog

Simpler than Sudoku and yet even more fiendish to solve, Slitherlink is probably the most pure logic puzzle ever invented. Can you draw a single loop while obeying the numbers in the grid? Don't visit '0'. Visit '1' 1 time. Visit '2' 2 times. Visit '3' 3 times. The rules are as easy as 1, 2, 3. Printed on top-quality paper, ideal for solving on, this book features 100 more top-quality puzzles from Dr Gareth Moore at a range of sizes and difficulty levels.
