1. Learning to Play Minesweeper
A Lesson in Deductive Reasoning
Go Forward

2. What is Reasoning?
Reasoning allows us to have an accurate understanding of the world.
Correct deductive reasoning allows us to make conclusions that are true, if our initial beliefs and theories are correct.
Inductive reasoning (the scientific method) allows us to have a high probability that our initial beliefs and theories are correct.
Deductive reasoning and inductive reasoning work together.

3. Deductive Reasoning is a Skill
Deductive reasoning is a skill that can be improved with practice.
As you practice you will get quicker and make less mistakes.
By improving your deductive reasoning skills you can solve many problems with better results and in a shorter time.

4. Why Learn Minesweeper?
Minesweeper is a game that can help your logical accuracy and speed.
Minesweeper is mostly “content-free”, meaning that it can help you develop better deductive reasoning skills without having to have a large pre-existing knowledge base.
Similar logical skills are used in technology troubleshooting and medical diagnoses.
By improving your deductive skills, you will get a more intuitive feel for how the computer behaves.

5. What Minesweeper Teaches
By playing the full game of minesweeper you will
learn to make hypotheses and later test those hypotheses.
learn how a wrong initial hypothesis will cause future wrong hypotheses.
learn “if, then, else” logic in you head.
learn to recognize patterns.
learn to filter out which information is relevant and not relevant to solve the problem at hand.

6. How You Will Learn
This edutainment game uses several strategies espoused by BrainSMART ® which can help you learn more efficiently and effectively. These include:
This is a simulator of a real game, showing you a game that was previously won, and how it was won.
By using a game simulator structure , it will help you have a low stress state that offers a challenge.
The game should be able to be completed in less than 20 minutes, which is within most people’s attention spans.
The game simulator will use a process of scaffolding, where it will help you build to being able to play the game on your own.
Having diagrams and graphics on the left side and written text on the right improves how our left and right brains process the information.
If you don’t understand something fully, make sure you click the “Go Back” button before continuing too far. The rules to Minesweeper are simple, but not always easy at first.

7. What You See When You First Start
This is the start of the game. The grid shows you all 81 squares that exist in beginner mode. 10 of these squares contain a mine (bomb), the other 71 squares are safe. Your goal is to left click on all the safe squares, and avoid left clicking any of the squares that contain a bomb.
Go Back
Go Forward

8. Your First Move
When you first start, you will have no idea about which squares contain a bomb, and which ones are safe. So when you first click, you pretty much do it randomly. The good news is that you have over an 85% chance of clicking on a safe square. For this simulation, click on the square under the magnifying glass.
Go Back

9. Starting the Logic
You were lucky on your first guess. Now, luck stops, and logic starts. From this point forward, if you do the right thinking, and the right moves, you should nearly always win. But to use the logic you need to understand what the numbers mean.
Go Back
Go Forward

10. Seeing Numbers
You now have a group of squares that are no longer beveled upwards. Some of these contain numbers, and some are blank. All of these squares are safe including those with numbers. The squares that are still beveled upwards are still unknown. They may be safe, or they may contain a bomb.
Go Back
Go Forward

11. What the Numbers Mean
The numbers in the squares are very important. Each number gives you a clue to where there might or might not be a bomb. But you must understand what the clues mean! The number tells you exactly how many bombs are neighbors to that square.
Go Back
Go Forward

12. An Example of a Number
Let’s focus on just one of the numbers right now and see what it means. Look at the 1 that the magnifying glass is on. This is telling us that there is only one bomb that is a neighbor to that square.
Go Back
Go Forward

13. Here is a Zoomed In Picture
We are going to Answer:
Which Squares are known?
Which Squares are unknown?
What is in the central square?
What does that mean?
Are the other numbers important at the moment?
Go Back
Go Forward

14. Squares that are Neighbors to a Number
There are a total of eight squares that are the neighbors of a number, some of these eight are unknown still, and some of them you have found to be safe. The magnifying glass is showing those eight squares.
Go Back
Go Forward

15. Beveled Squares Around a Number
Of the eight squares that are neighbors to this 1, only the five that are beveled are still unknown about whether they contain a bomb or not. This means that if you were to randomly click one of those, you would have a one out of five chance of hitting a bomb. This may sound like good odds, but we can do better!
Go Back
Go Forward

16. Finding a Better Numbered Square to Start With
To consistently win the game, you need to find a square that you are 100% sure will not contain a bomb. This is called deductive reasoning. But to do this, we must first find a square that we are 100% sure IS a bomb.

18. Looking For Corners and 1s
Lets look at a different numbered square that might be a better clue. Squares that contain the number 1 in the outside corner of a group of unknown squares are a good place to start. In this game there are four of these spots.

19. Honing In On a Good Starting Square
To understand why squares in the corners are good starting places, we will look at an individual one, and see what it means. The 1 means there is only 1 bomb that is a neighbor to that square. In the case of a corner, there is only 1 unknown square, so it MUST be a bomb.
Go Back
Go Forward

20. Let’s Focus on this Square
Try to Answer:
What does the center square tell us?
Is one of its neighbors a bomb?
If so, which one?
Go Back
Go Forward

21. Don’t Left Click the Square
While logic tells us that the square with the magnifying glass must be a bomb, at this point you can only hypothesize that the square is a bomb. You can do this hypothesis by clicking the RIGHT mouse button on top of the square. This will place a flag on that square.
Go Back
Go Forward

22. Pretending We Are Right Clicking
In this simulator we can not actually click the right mouse button. But we will pretend to do this, by clicking on the right button on the mouse on this screen:
Go Back

23. What the Flag Means
After you right click on the square, a flag will appear. This means you think there is a bomb there. If you are using correct logic then there really is a bomb there. If you’re logic is wrong, then there isn’t, and it will mess up the rest of your logic. (The good news is that our logic is good so far!)
Go Back
Go Forward

24. Let’s Focus on a Different Square Now
We Will Answer:
What does the center square tell us?
Is one of its neighbors a bomb?
If so, which one?
Are there any unknown beveled squares that are safe?
Go Back
Go Forward

25. Now that We Know Where a Bomb Is, Let’s Find Out Where One Isn’t
The numbers can tell us where bombs are. If we use deductive reasoning, they can also tell us where the bombs aren’t. Lets look at another 1 on the board. We know that this tells us that there is only one bomb as a neighbor. But because of our last move, we now know where that bomb is. (Where the flag is)
Go Back
Go Forward

26. Guessing a Safe Square
Since we have already found the 1 bomb that surrounds this square, this means that any other unknown squares neighboring the 1 must be safe. Click on the known safe square that the magnifying glass is showing you to continue.
Go Back

27. Good Job, Let’s Try Another
That square was safe, and says there is 1 bomb next to it. There are currently 3 beveled squares that are its neighbors, and one of them is the bomb we found earlier, so both of the other neighboring squares must be safe. Click on the one the magnifying glass moves to and we will see if it really is safe.
Go Back

28. Keep Going
We found a safe square again, and once again it tells us that there is 1 bomb neighboring it. And once again, we still know which one is that bomb. So we know all the other squares around it are safe. Click on the one the magnifying glass moves to and we will make sure it is safe.
Go Back

29. You Cleared a Few
That click cleared several spots, leaving us with a lone beveled square that is a bomb. We can tell it is a bomb, because the squares with a 1 next to it only have it as an unknown. And the squares with the number 2 only have it and the other known bomb as neighbors.
Go Back
Go Forward

30. Pretend Again to Right Click
This simulation still doesn’t have the right click working, so once again, click on the right side of the mouse picture to pretend to right click on the magnifying glass:
Go Back

31. Now That We Flagged That Square, Let’s Find Another
We will keep doing the corner strategy to flag bombs. We need to pretend to right click again, to flag the bomb where the magnifying glass is.
Go Back

32. Can You Find a Safe Square?
There are actually several safe squares next to the 1 that the magnifying glass is on. See if you can click on one of the safe squares. (If you click one of them, we will click the other two for you.)
Go Back

33. Which One Should Be Flagged Now?
Now that we cleared those squares, we are at a point where we can find another bomb based upon what we just did. Click where you think the bomb is. (Remember in the real game you would right click to put a flag there. But this simulator can’t do right clicks.)
Go Back

34. We are Going to Fast Forward Now
See if you can find the next safe square based upon the logic we have been using. Look for a square by the square we just flagged that logic tells us is safe. Once you click the right square, this simulator will do some more moves for you. (The real game won’t!)

37. Faced With the Number 2
So far we have mostly dealt with using squares that have a 1 in them to figure things out. But squares that contain a 2 can also be useful. Remember that the number tells you how many bombs surround it. Try to figure out from the square the magnifying glass is on, which other square has a bomb? Then click where you think the bomb is.
Go Back

38. You Flagged the Bomb
Now lets go back to using the number 1 as our clue. Click the next safe square based upon the square that has a 1.
Go Back

39. You Are Doing Good
Try another one that might be safe based upon the one you just clicked.
Go Back

40. Keep Going
You are doing good. Why don’t you click on the next one that is safe based upon the square with a 1.
Go Back

41. Many Options
At this point, there are many options for continuing. We could go back to using the squares with the number 1 in them, or we could find safe squares based upon those that have a 2. Or we could challenge ourselves…
Go Back
Go Forward

42. Challenge: Using Advanced Logic
By looking just at the three squares that have a 2 in them, with some advanced logic, you can deduce which unknown square has a bomb.
If you want a challenge, try to figure out which one needs to be flagged as a bomb. This is fairly advanced, so if you want to just have us do it for you, click the button below:
Go Back
Skip the Advanced Logic, Just Flag the Bomb for Me!

43. Here is the Bomb
Ok, now you have learned most of the basic logic that is needed to win a beginning level game. Sometimes there is even more advanced logic that is needed when playing on intermediate or expert mode.
But for now you have done enough, and we will do some more moves for you, so sit back and relax…
