Treep first saw Rubik's Cubes in a department store in the summer of 1980, and received one for her birthday a few months later. She found a solution without assistance within a few weeks. She co-founded the Nederlandse Kubus Club (Dutch Cube Club) with Jost van Rossum, producing the first newsletter on her mother's typewriter.[Scheffler]
In 1981 Anneke Treep and Kurt Dockhorn developed an early form of the CFOP method. It became known in the Netherlands as the "Dockhorn-Treep system" after Frans Schiereck published it in one of his 1981 books.
For the next few years a group including Treep, Kurt Dockhorn, his brother Hans (who had access to a computer), and Guus Razoux Schultz, documented all of the OLL and PLL cases, and devised algorithms for nearly 1200 possible arrangements of the last layer.[Scheffler]
A keen puzzle-enthusiast, she has designed many (non-twisty) puzzles and games.
