Books

International Coloring

Physical paperback puzzle and coloring books available on Amazon, including large-print puzzles and detailed adult coloring titles.

The catalog is built around a few focused series. The large print sudoku line runs from easy through hard in five volumes, with one puzzle per page and answers in back. The Extreme and Unhinged sudoku books carry SER difficulty bands on the cover for solvers who want a stated challenge level, and the kakuro line covers easy through medium-hard grids in the same large print format. The Still Got It series packs word, number, and variety puzzles into gift-friendly volumes, and the nostalgia word search books revisit the 80s and 90s one themed grid at a time.

Adult coloring paperbacks cover cozy interiors, fairyland scenes, classic tattoo flash, and dark biomechanical art, each with 50 single-sided pages. The international shelf carries word search and cryptogram editions in Spanish, Italian, Portuguese, German, and French. Most coloring titles also have a printable PDF twin listed under digital products if you would rather print pages at home.
