Is this a book of logic puzzles or a coloring book?Why not both? The intricate, visually appealing puzzles in this book are based on slitherlink: a sudoku-like puzzle that involves drawing lines on a grid of dots to form one big loop.Standard slitherlink puzzles are solved on a square grid, with each clue indicating how many sides of the surrounding square have lines drawn on them.This book, however, features elaborate tiled grids with triangles, hexagons, octagons, and more, allowing for endless variations from page to page.The gorgeous kaleidoscopic designs can be colored before, after, or even during solving.Mind-bending as the puzzles may seem, a warm-up section of standard slitherlink followed by easy kaleidoscope puzzles (plus help from a detailed tutorial) will offer a welcoming experience for all levels of solver.
