FAQ
Can I print it for my class?
Yes. The $5 book includes a classroom licence: one teacher may print and photocopy unlimited copies for their own students, every year, and share pages through a password-protected class site or LMS. The $19 school licence covers every teacher at one school.
What ages is it for?
Easy puzzles suit confident readers from about grade 3. Medium and hard puzzles challenge middle schoolers and adults, and hard Brick Pyramids need a letter for an unknown brick, like a mini algebra problem.
Does every puzzle have one answer?
Every Cage Grid and Brick Pyramid was checked by a solver program: exactly one solution, no guessing needed. Target puzzles often have several routes; the answer key shows one, and any correct route counts.
Why not free worksheets?
Free sheets are fine for a one-off, and the 18-puzzle sampler is free too. The book saves you the hunting: three puzzle kinds in one consistent, print-ready design, levelled from easy to hard, with every answer and a licence that covers your classroom.
Are the puzzles original?
Yes. Every puzzle was generated and checked by CyberMax's own puzzle programs, the same engine family as Sumbloom, the free daily number puzzle.
