About puzzle #5
Puzzle #5 is the one for Wednesday 7 October 2026: a medium Wednesday puzzle, in Caesar shift. Every letter is moved the same number of places along the alphabet, wrapping from Z back to A. With only 25 shifts, trying them all is quick.
Stuck? The Caesar shift decoder is fair to use, and Hint fills in one letter at a time. A new puzzle opens every day at midnight where you are, at StringMash Daily, and every earlier one is in the archive under the puzzle.
