You’re staring at a grid. It’s mostly empty. Maybe there are two or three numbers scattered like lonely islands in a sea of white boxes. Most people look at that and walk away. But then you see Simon Anthony or Mark Goodliffe on a screen, grinning like they’ve just been handed the keys to a chocolate factory. They see a single line—a "thermometer" or a "killer cage"—and suddenly, the whole puzzle starts to collapse. That’s the magic of cracking the cryptic sudoku.
It’s not just about numbers 1 through 9 anymore. Honestly, the old-school newspaper puzzles feel a bit like doing taxes compared to this. We’re talking about a global phenomenon that turned a logic game into a spectator sport.
The Shift From Math to Logic
Most people think sudoku is about math. It’s not. It never has been, but the "cryptic" variety really hammers that point home. When you’re cracking the cryptic sudoku, you’re looking for patterns, constraints, and weird little interactions that the setter—the person who designed the puzzle—left for you to find.
Think of it like a conversation. The setter is whispering clues.
The "Miracle Sudoku" is probably the best example of this. It's a legendary video on the Cracking the Cryptic YouTube channel. There are only two given numbers in the entire grid. Two. Most people thought it was a joke or a mistake. But because of the specific constraints—things like King’s Move (where numbers can’t be a chess-knight’s move away from themselves)—the puzzle is actually completely logical. Watching Simon realize how the digits 1 and 2 forced every other number into place was a genuine "internet moment." It wasn't just gaming; it was art.
Why Constraints Actually Make It Easier
It sounds backwards, right? Adding more rules should make the game harder. But in the world of cracking the cryptic sudoku, rules are actually your friends.
Take "Killer Sudoku." You get these dashed-line cages with a small number in the corner. That number is the sum of all the digits inside the cage. If you have a two-cell cage that must sum to 3, those cells have to be 1 and 2. You’ve just eliminated seven other possibilities. Suddenly, the infinite void of the grid starts to feel manageable.
- Thermometers: Numbers must increase from the bulb to the tip.
- Arrows: The digits along the shaft must sum to the number in the circle.
- Palindromes: The sequence of digits is the same forwards and backwards.
- Kropki Dots: Black dots mean one number is double the other; white dots mean they are consecutive.
The Human Element in a Digital Grid
We have to talk about Simon Anthony and Mark Goodliffe. They aren't just "influencers." They are former UK Team members for the World Puzzle Championships. They bring a level of E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) that is rare in the gaming world. When they explain a "X-Wing" or a "Swordfish" technique, they aren't reading from a manual. They are sharing a lifetime of competitive logic.
There’s something weirdly soothing about it. You’ve got these two British guys, often wearing slightly wrinkled shirts, getting genuinely excited about a "hidden triple." It’s wholesome. It’s the antithesis of the loud, high-energy "Let's Play" culture that dominates Twitch and YouTube.
The Setters are the Real Stars
While Simon and Mark are the faces, the setters are the architects. Names like Phistomefel, Clover, Gas, and Bremster are celebrities in this niche. A Phistomefel puzzle is known for being terrifyingly elegant, often using "Set Theory" (not the math class kind, but a specific way of looking at regions in a sudoku) to break the grid open.

These aren't computer-generated. A computer can spit out a billion "Hard" sudokus that require tedious "pencil marking" and guessing. A hand-set puzzle? That’s different. Every step is intentional. There is a "break-in"—that first "Aha!" moment where you find the one logic thread that unravels the whole thing. If you haven't felt that rush, you haven't really experienced cracking the cryptic sudoku.
How to Actually Get Good at This
Stop guessing. Seriously.
If you find yourself saying "I'll just put a 5 here and see if it works," you’ve already lost. The beauty of these puzzles is that they never require a guess. If you’re stuck, you’re missing a constraint. Maybe you forgot that two cells are connected by a German Whispers line (where adjacent digits must have a difference of at least 5). Maybe you missed a "sandwich sum."
Focus on the "Low Hanging Fruit"
Start with the most restrictive rules. If there’s a "Renban" line (a line of consecutive digits in any order) that is 9 cells long, you know exactly what’s on it: 1, 2, 3, 4, 5, 6, 7, 8, and 9. It’s a gift. Use it.
I used to struggle with the "Little Killer" clues—the numbers outside the grid with arrows pointing diagonally. I'd try to do the math in my head and fail. Then I realized: it’s all about the intersections. Where two clues cross is where the answer lives. It’s basically detective work with numbers.
The Psychological Hook
Why do we do this? Why do millions of people watch a 40-minute video of a man solving a puzzle?
It’s about order. We live in a world that is, frankly, pretty chaotic. You can’t control the economy or the weather. But you can control a 9x9 grid. There is a definitive answer. There is a logical path to get there. When you’re cracking the cryptic sudoku, you’re engaging in a pure form of problem-solving that provides a dopamine hit every time a digit clicks into place.
It's also about the community. Discord servers like "Seven-Sided Die" or the Cracking the Cryptic official server are buzzing with people helping each other. It’s not competitive in a mean way. It’s collaborative. People share "hints" that are just vague enough to let you still feel smart when you solve it.
Common Misconceptions That Hold You Back
People think you need to be a "math person." I've seen English professors solve these faster than engineers. It's about visual pattern recognition.
Another big one: "I need to memorize dozens of techniques." Not really. You just need to understand how numbers interact. If you know that a row must contain 1-9, and you see three cells that must contain 1, 2, and 3, then no other cell in that row can be a 1, 2, or 3. That’s it. That’s a "naked triple." It sounds fancy, but it’s just common sense.
What to Do Next
If you want to move beyond the Sunday paper and start cracking the cryptic sudoku like a pro, here is how you actually start.
First, download the "Classic Sudoku" or "Sandwich Sudoku" apps produced by the Cracking the Cryptic team. They are specifically designed to teach you the logic rather than just testing your patience. They have a "hint" system that explains the why, not just the what.
Second, watch the "Miracle Sudoku" video. Even if you don't play, it’s a masterclass in human intuition.
Finally, try a "Gas" puzzle. "Gas" stands for "Genuinely Approachable Sudoku." These are designed by a setter named Clover and others specifically for people who are new to the cryptic world. They give you that "expert" feeling without the four-hour headache.
Start looking for the "negative constraints." Sometimes, the fact that a number can't go somewhere is more important than where it can. Once you see the empty spaces for what they are—locked doors waiting for the right key—the grid stops being a cage and starts being a playground.
Stop looking at the whole grid. Find one small box. One line. One rule. The rest will follow.
