In 2023, I posed 23 challenges as part of the Gizmodo Monday Puzzle series. Some require a bit of math, and others a light familiarity with physics; but most can be solved through logic and creative thinking. For each of the following puzzles, I provide a link to the solution, but I suggest you resist the temptation to look as soon as you feel stumped—the answer may come to you with just a little more contemplation. These challenges are difficult, but they are nearly all solvable without specialized knowledge. Good luck!
