Cracking The Cryptic.

A love letter to the YouTube channel that built the variant sudoku community we get to be part of.

Who they are

Mark Goodliffe and Simon Anthony run Cracking The Cryptic — a channel that publishes long-form solves of hand-crafted logic puzzles, almost daily. They've made thousands of videos at this point. Mark and Simon are both elite competitive solvers (Times crossword champions, sudoku grand prix podium finishers) and the channel is what happens when serious solvers sit down to actually think out loud.

They didn't invent variant sudoku. But they're the reason a lot of us know it exists.

Why they matter

  • They turned variant sudoku from a hobby a few hundred people shared into a creative scene with thousands of setters and hundreds of thousands of solvers.
  • They discovered and championed setters whose work would otherwise have stayed buried in forum threads.
  • They made hard puzzles approachable — not by dumbing anything down, but by being patient enough to explain every step of the logic, even when it gets weird.
  • Their format (one solver, one puzzle, real-time think-aloud) is now the genre standard. Every channel doing variant sudoku is, in some sense, doing a version of what they did first.
  • They take the puzzles seriously. Setters take them seriously back. The whole community is better for it.
