How to play
  1. Each cipher letter (small gold letter) stands for one real letter. The substitution stays the same across the whole puzzle.
  2. Tap or click a letter, then type your guess on your keyboard or the keys above. Every matching cipher letter fills in at once.
  3. Stuck? Reveal a letter up to three times, or switch on Show mistakes.
  4. No letter ever stands for itself. Short words like A, I and THE are good places to start.
