Brain crackers | Puzzle Booklet by ORTEC & WCPN

Are you into puzzles, too? In cooperation with the World Class Puzzles from the Netherlands association (WCPN), we like to offer our puzzle booklet 'Brain crackers' for free. In the booklet, you'll find many handmade puzzles created by enthusiastic ORTEC employees and WCPN, in different categories; from logic puzzles to sudokus to what we like to call 'typical ORTEC puzzles'. Those are the kind of puzzles that challenge us on a daily basis.

🧩 Download your puzzle booklet (PDF) for free below.
