Welcome to the clickmazes collection! Online since 1997 offering an eclectic selection of puzzles and mazes all playable right here in your browser. Clickmazes is the original home of plank-puzzles, wriggle and boxup among many other curiosities of the route-finding genre.

New for November 2021: Many new puzzlescript apps now available at A mix of old and new material, including many new apps based on the puzzling output of Erich Friedman.

The cheerpj transpiled applets (introduced October 2020) have now been phased out. Sadly this means some old content is currently unavailable in interactive form. Let me know if there is something missing you would like reinstated sooner rather than later.

Andrea - a potted history

As a child in the 70s I drew free-hand mazes, ever larger and ever more detailed, on 2D and then 3D surfaces. In the 80s I preferred form and structure, strong patterns that could be broken in small ways to produce elegant mazes. In the 90s I turned increasingly to rules and logic to add extra layers of complexity. More and more I lent on my own (and others) software engineering skills to help create, prove and solve my mazes. In the late 90s the web, and in particular java, finally provided me with the perfect tools to launch and share my ideas and opened up a whole new range of possibilities. The web-based, interactive puzzle-maze, or the clickmaze.

The noughties saw an explosion of creatively and new content, thanks in no small part to much encouragement and many great contributions from some world-class coding-wizards, puzzle-designers and computational-complexity boffins. This was the decade that made the NEWS and rewrote the RULES. It rocked, rolled, wriggled, pushed-the-box and walked-the-perilous-plank. Could anything spoil the fun?

Well, the tensies arrived. Support for java applets was waning fast, it was like staring at a black-hole at the end of a no-U-turn maze. And my audience was drawn away, by the dazzle of tablets and phones and downloadable puzzle apps. By 2014 my site was all but moth-balled. Was it CTRL-ALT-DEL for clickmazes? But an old puzzle-designer does not stop once she is proven PSPACE-complete and old applets do not die they just wait for the right transpiler. 2020 was a strong, bright light to aim for in my personal maze-of-life. Retirement and a reboot beckoned.

"Hello. IT. Have you tried switching it off and on again? " (IT Crowd - 2010)

So here we are in yet another decade. Reboot complete, so what next?
You and I alike, will have to wait and see.
