We make puzzle books and printable games built around the number pyramid: every brick is made from the two bricks under it, and you work your way to the top. We use the same idea in many different kinds of puzzle, for kids, families, classrooms, teens and adults.
Every puzzle is made with answers and a worked solution, and our books and games are checked by solving them before they go out. Creouts Publishing is the only name on all of our work.
Math pyramid puzzle books, puzzle adventure gamebooks (don’t read them in order: you turn to the page your answer sends you to) and deluxe hardcovers, in paperback and hardcover, in English and several other languages. Our flagship picks:

Level 1 of our flagship series: a math puzzle book where every locked chamber opens with a number pyramid. 45 chambers and 6 treasure rooms.
