This is a collection of monoportal puzzles that I personally find to be some of the best on the workshop, and that I think should be played if you want inspiration to make your own monoportal maps. These maps are not in any particular order, and the collection might be edited/expanded at any given point. Difficulty of puzzles might vary, consult the description of each map for more information.

You can check a list of each map's mechanics and interactions at the "Monoportal Hall of Fame" section of "HugoBDesigner's Guide to Monoportal Mapping":

Feel free to recommend me monoportal maps and I'll check them out whenever possible. If they're good enough, they might get featured here too, as well as on my guide!
