I’m a huge fan of all sorts of puzzles (especially logic puzzles with a mathematical flair). As an enthusiast and sometimes-creator of escape rooms, I love creating various types of original puzzle—some of them which work online are exhibited here, as well as non-original puzzles I have heard elsewhere and loved.
