PeterFrank was founded in 2000 by Peter De Schepper and Frank Coussement. Their internationally registered trademark, BrainSnack®, stands for challenging, language-independent, logical puzzles and mind games for kids, teens, and adults. It also stands for high quality puzzles. Whether they are made by hand like the visual puzzles or generated by computer like Sudoku, all puzzles are tested by the target group they were made for before using them. In order to guarantee that the computer generated puzzles can actually be solved by humans, they make programs that only use human logic algorithms.
