Key Takeaways:
What Is Sudoku?
Sudoku is a popular mathematical word puzzle played on a grid of typically 9 x 9 cells divided into complete unit squares. It is generally believed to have been invented or at least popularized by the Swiss mathematician Leonhard Euler who mentioned the puzzle in 1783. The goal of this game is to place the integers 1-9 such that no number is repeated horizontally, vertically, or in the three-by-three mini-grids within the main grid or box.
What Are the Rules of Sudoku?
The rules of Sudoku are that you fill a 9×9 grid so that each column, each row, and each of the nine 3×3 subgrids that compose the grid contain different numbers from 1 to 9.TopCoder suggests as a simplification of these rules that one look for a lone missing number in the rows, columns, or grids and place the missing number there. A very simple breeze through these rules will allow solvers to begin playing and solving the puzzle of Sudoku. The grids can be solved in any order as long as one works simultaneously on the rows and columns to comply with the conditions mentioned earlier. Or here is a more complete but straight to the point guide with these points.
- Sudoku is played on a 9×9 grid (81 squares) composed of 3×3 subgrids (nine 3×3 squares).
- Fill in the grid so that every row, every column, and every 3×3 subgrid contains the digits 1 through 9.
- There is only one solution for the completed puzzle.
- Digits cannot be repeated in rows.
- Digits cannot be repeated in columns.
- Digits cannot be repeated in 3×3 sub-grids.
Why Do People Cheat in Sudoku?
People cheat in sudoku to get beyond their personal difficulty thresholds. If the sudoku puzzles are too easy for them, they may feel they are wasting time. If the problems are too hard, they get stressed. Sudoku is more competitive in nature, as there are time limits for national championships and computer competitions. These duress conditions may force some to cheat, as there is added pressure to secure the win.
Sudoku helps and lowers stress levels for elders who like to solve the puzzles. It is probable that if the puzzles are too difficult, they would cheat if they lack the time to spend on overly complex problems. They may not cheat if they can devote hours to difficult problems the way some of the most dedicated Rubik’s cube solvers have learned to solve the puzzle.
So far, there is no data to confirm the extent of cheating within sudoku.
To Solve Difficult Puzzles
You can use debugging in Sudoku to create simpler sub-solutions to difficult puzzles. After looking for numerous possibilities in a game, many Sudoku solvers screen for fewer options. Then, if you can’t eliminate all of these options during a set analysis, you may use the more advanced methods to find a new option. This helps to reduce the number of operations you have to search for all possible solutions to find a new solution in a timely manner.
To Impress Others
Those who want to cheat Sudoku to impress others might try the free mobile game called Unlock the Grid. The rules of Unlock the Grid are similar to Sudoku. The player is asked to enter the numbers from 1 to 9 in each row, in each column, and in each of the nine 3×3 sub-grids. The fun part about this game is that it is time-limited and the game itself starts to fill in some numbers. Gameplay begins with just 5 minutes on the clock, and for each shared number, players receive an extra 30-second increase. Rapid pattern recognition is needed to achieve the Target time, but this can greatly impress anyone watching. It’s available on the Play store or the App store and was developed by Toward Bogga Neat.
To Win Competitions
- Enter competitions based on being the first to finish a sudoku in the fastest time. This is generally on the honor system unless for a major sports event, in which case Wikipedia generally provides a unified set of rules.
- Acquire physical copies of sudoku booklets such as The New York Times Big Book of Bali, Kappa Sudoku Puzzles, Super Challenge Sudoku, or any sudoku booklets by Thomas Snyder, Tetsuya Noshikawa, Nikoli, etc. Study the solution that is provided or in the case of NYT Big Book of Bali, look at the reflection of the puzzle on the other side of the page. This will provide you with shortcuts you would not have thought of.
- Use an automatic sudoku solving program which bases its solving techniques purely on logic. This can be done either with a sudoku-robot as done by Massachusetts Institute of Technology (MIT) programmers, or by using the sudoku playing assistants we mentioned before. In the case of sudoku-assistants, make sure the setting is turned to the logic-compliance mode to avoid frustrations of an artificially-intelligent machine taking over the game.
What Are the Different Ways to Cheat in Sudoku?
The different ways to cheat in Sudoku are to fake answers up, to reverse engineer a higher numbered puzzle into the lower numbered puzzle that you need to solve, to manipulate the content of the Sudoku code, or to alter your tool preferences in websites or applications. Cheating in Sudoku is often possible by carefully designed software that does all the work for the user.
Faking answers can be as simple as writing answers down and erasing them as needed. To do this symbolically conflate the completed Sudoku from the previous day with answers you want in the new one. In essence, you are making the same puzzle, just taking it a little further along the path toward completion.
Some Sudoku cheats are incredibly easy to implement and do not even need retooling software. Some cheating software does everything. But even if one has no inclination to cheat, using Sudoku tools can make the puzzle solving easier. You are recognizing that you have already saved time by setting up Sudoku helper tools and guides.
Using Sudoku solvers, apps, and websites increases the chances of cheating in Sudoku. You will tend to become dependent on them and depending on the specific features your tools of choice have, you could easily be mistakingly cheating without even knowing.
Using Pencil Marks
Sudoku books often recommend that to make the game easier, you fill in pencil marks on each box to note which numbers can go in the box. Many guidebooks recommend you avoid this trick to make the game harder, so one way to cheat with pencil marks is to use them to crack problems you do not know how to solve. Pencil marks help identify which numbers are blocked by another number in the same sequence of the 3×3 block and/or line. This is essential for the hardest puzzles near the end of the game, but you can shortcut to it by jotting down pencil marks in every box immediately after you fill them.
Using Computer Solvers
You can cheat at Sudoku by using computer solvers. Computer solvers are computer programs or applications that fill in Sudoku puzzles for you. They work by dynamically breaking down problems into smaller and smaller pieces until they are simple enough that computers can solve them in a few milliseconds.
There are three technologies that top solvers rely on:
-
The backtracking approach essentially constructs each potential solution, then compares these solutions to verify their validity. If they don’t work, the computer hits the backtracking mechanism and adjusts its approach to finding another solution.
-
The Dancing Links technique works by repeatedly reducing the original N X N Exact Cover problem to a series of smaller and smaller subproblems until all of the decision variables are assigned so that each row and column have one 1 in them and each 1 covers exactly one cell.
-
Efficiency-aiding data structures when coupled with a large set of algorithms for picking and removing elements, forming and balancing nodes, and efficient case scenarios can significantly affect the program’s runtime.
Using Solving Techniques
Using simple Sudoku-solving techniques allows you to cheat in the sense that you are deliberately stifling creativity in yourself like you are not being here to win, just to not lose. This is because making the answers up in your head is much easier than moving numbers around on the grid to confirm their validity. Here are some techniques:
- One or Two Method: If trying to solve a cell, make a list of possible numbers and try each one in your head. After only following the logic, one or maybe two numbers should remain.
- Unique Rectangles: They solve cells when repeated bivalue cells are found.
- Inference Chain: This technique identifies patterns of alternating Strong and Weak cells and makes assumptions based on possible numbers that allow one to eliminate a large portion of the Sudoku grid before invalidating those numbers.
Is It Ethical to Cheat in Sudoku?
It is not ethical to cheat in Sudoku, but whether it is a grave enough offense to elicit punitive measures is subjective. For many people’s enjoyment, it is vital for them to exercise their grey cells and resolve bad Sudoku streaks on their own. Constant cheating can over time actually dull one’s critical thinking skills in the long run.
Manners expert Diane Gottsman explains how it’s okay to cheat sometimes to get to the solution after you have struggled but to recognize when you have started relying on the cheating or you’re doing it too often. It’s like saying it’s okay to have a piece of chocolate after dinner but if you have an entire pie after you finish every meal, it becomes too much.
Although legendary -bullet chess player Andy Soltis says the internet will only grow to provide more detailed analyses about solutions, just as contemporary crossword puzzles, it takes away something from what was initially a simple game. In essence, Sudoku was a challenge that individuals could pick up in their off hours. Now that most turn to computers to optimize their daily schedules and multitask, the game becomes just another takeaway.
It is okay if you are occasionally stuck to take help from an AI program or another external source. Provided that one is able to recover from mistakes and try again. But cheating should be the exception rather than the rule.
Opinions of Sudoku Experts
The opinions of Sudoku experts vary regarding whether or not it is cheating to use advanced techniques. According to World Sudoku Champion Thomas Snyder, there is no cheating when it comes to solving Sudokus. Apart from generating brand new puzzles, software solvers usually also provide the intermediate hints that a human can figure out. It’s just that most people don’t want to spend the time to become a Sudoku expert. Andrew Stuart, the author of The Logic of Sudoku and developer of the advanced software solving system sudokuwiki.org believes that using pencil marks in a sudoku is not cheating because it is simply a visual aide to help solve the inferences mentally. It would be cheating if it was visible to other information not found in the positions themselves.
Opinions of Players
Player opinions on Sunderland forums were noted by the UK’s The Sun newspaper in a Reuters report that real concentration is needed while playing sudoku, and cheats on newspaper sudoku are rarely used. There is even mention of opponent AI in the more-favored online game, Sudoku Arena. An unidentified player in The Guardian‘s Ask Hadley column felt that Sudoku Arena’s opponents always played instantaneous move whenever they were losing, so it seemed as if they had some kind of AI opponent.
How to Avoid Cheating in Sudoku?
There are various methods to prevent cheating in Sudoku:
- Use a Sudoku journal: Cell phone apps like Andrwea the Assistant and pencil/paper Sudoku games can offer anti-cheating options.
- Use a more difficult puzzle: A higher-difficulty level puzzle will keep a player’s mind engaged.
- Have a time limit: Setting a time limit to solve a Sudoku page might help to discourage cheating in Sudoku.
Practice and Develop Skills
There is no proven way to cheat in sudoku, but learning new mathematical approaches is often thought of as cheating or unfair practice. The best way to enhance your abilities at Sudoku without utilizing unfair advantages, according to Assistant Professor Dr. Lisa Stephenson at Fairfield University in Connecticut, is to practice. Solving Sudoku puzzles on a regular basis helps you see them in new ways and has a quantifiable impact on brain function. You can start with simplified beginner puzzles and work your way up to expert level. As you solve more puzzles, you will become more adept at looking at new aspects of the puzzle, work faster, and enjoy it more.
Use Tips and Strategies
You do not need software to cheat at sudoku to reach the solution. There are many tips, tricks, and strategies you can follow to determine potential numbers and solve the puzzle manually. Use the strategies you find easier to solve the puzzle without any tools.
Cross-hatching, known as the Pencil marking, is even simpler as this technique requires you to mentally envision the possibilities.
Swordfish, Jellyfish, the XY-wing technique, as well as the Remote Pairs technique are more advanced strategies that will help you solve puzzles that are more complex without using any cheating tools.
If you believe the puzzle is overcomplicated to the point of illegitimacy, plug the numbers into one of the sudoku puzzle solvers or generators available on the internet just to be sure. Of course, our conclusion is that one should properly try all of the four difficulty levels before jumping to cheat tools altogether.
Ask for Help or Hints
Sudoku Cheats. Get help if you are not able to solve a sudoku puzzle on your own through excellent learning resources and cheating sudoku helper sites. Cheating sudoku can even have its place in helping you to learn new strategies and techniques. Cheating is best for Sudoku players who need hints they can review but do not want to see the answer upfront. Get a Sudoku cheat sheet by inputing your in-progress game into the Sudoku exchange, and it will tell you where new numbers can be input.
What Are the Benefits of Solving Sudoku Without Cheating?
The benefits of solving Sudoku without cheating include the following according to the exercise science department at the University of South Carolina Aiken and the Keck School of Medicine of Southern California:
- Improvement of cognitive skills: Certain cognitive skills like attention, working memory, vision, and spatial reasoning are shown to improve through the practice of Sudoku and these benefits are most noticeable when it is done without any help.
- Improvement of decision-making skills: Study of the impact of playing Sudoku on psychiatric patients has found a positive impact on decision-making skills. Improving decision-making skills is a valuable benefit for daily lives and can help one improve general decision-making processes.
- Reduction of memory decline: Cognitive activities may contribute to enhancing brain performance. According to the Keck School of Medicine, stimulating the brain, especially at a later age, helps in preventing memory decline. This is because playing Sudoku requires constant reasoning, memory, and brain connection that helps reduce memory loss with age.
Mental Stimulation
This is when a puzzle is not too hard and not too easy, which tends to happen quite frequently when cheating. Sudoku has a dedicated fandom of players who have been known to lament that puzzles are getting easier.
Mental stimulation broadens the definition of cheating to include notes or other memory-utilizing aides. According to the magazine The Week, though such tactics are a common method of helping people ‘cheat’ in Sudoku, magnetic resonance imaging (MRI) and electroencephalogram (EEG) tests have found that such brain activities help to energize the mind, even if cheating.
Improved Problem-Solving Skills
One method to ‘cheat at sudoku’ is no method at all. As it is often the case that these approaches provide helpful hints towards some of the logic required to solve the puzzle, rather than shortcuts or canned approaches. After reviewing ‘improving your problem-solving abilities with math games’ research from Hindawi’s Education Research International for the University of Wisconsin – Stout by Christophe Lajoie in 2019, the document outs that many mathematical games improve problem-solving skills. However, the specific puzzle games described are not mentioned. While this EU pedagogical material describes potential educational impacts of crossword puzzles, these same points would apply to one’s understanding of sudoku. Instead of explicitly looking up ‘how to cheat sudoku’ look into appropriate puzzle and logic games in order to build these mental skills in order to succeed at sudoku in a more honest, and fulfilling way.
Personal Satisfaction
Personal satisfaction is another reason people engage in cheating in sudoku. Punching answers to highly challenging conundrums into computers can often reveal their solutions, and the website WebSudoku has received complaints for offering too much help in the form of possible answers. Depending on what your initial motives are for personal satisfaction, cheating can either raise or doom your ability to claim personal satisfaction.
