Pip Frames
A calm logic puzzle with dominoes. Lay the pieces in a closed square frame so that every pair of touching ends matches. Every puzzle has exactly one answer, and you can always reach it by deduction, never by guessing.
450 puzzles in three chapters
Chapter I teaches the frame and builds up over 150 puzzles. Chapter II brings magic borders, where every side of the frame adds up to the same total. Chapter III adds crossroads: lines across the frame, each with its own total. Each chapter climbs in bands from gentle to tough, and every new band starts a little easier than the last one ended.
