How to always win at Rock, Paper, Scissors. How to win in the game rock-paper-scissors? (implementation of optimal strategy in Wolfram Mathematica) How to win at rock scissors

Instructions

The “classic” version uses only three gestures – rock, scissors and paper. The stone is a hand clenched into a fist, the scissors are the middle and index fingers straightened, while all the others are clenched. The paper is a hand with outstretched fingers, palm down.

The game begins with the phrase “Rock-paper-scissors, one, two, three!” In various post-Soviet countries, instead of “one, two, three” there were various combinations such as “tsu, e, fa”, “chu, va, chi”, “ko, zi, ko”, “en, den, tso”. After the phrase is spoken, the participants in the game must simultaneously throw out their hands in a gesture indicating the pieces they have chosen.

The paper covers the stone, the stone dulls the scissors, the scissors cut the paper. Thus, all participants have an equal chance to win. If at least three people from the company throw different gestures, that is, there is rock, scissors, and paper, then a draw is declared and the round is replayed.

Over the years, the game "rock-paper-scissors" has undergone various changes. For example, in some areas a well is involved. In this case, the counting sounds like this: “Rock-paper-scissors, and you need a well too, one, two, three!” During this game, the paper defeats both the stone and the well, but the stone and scissors drown in the well. The well is shown with a gesture in the form of a loosely clenched fist. In addition to the well, in different countries a pencil, fire, water, bottle, tree, pistol, lightning, sponge, and other things invented from different parts of the globe may appear in the game.

You can introduce gestures that you have invented yourself into the game, without forgetting to come up with rules for which figure wins in which case. For example, in the famous “The Big Bang Theory” Sheldon Cooper proposed his own version of the game: “rock-paper-scissors-Spock”.

No conscientious person will say that he likes to lose. Everyone is united in the fact that they invariably strive to win in various areas of life. However, some succeed, seemingly without much effort, while others face failure over and over again. What needs to be done to never part with the laurels of a winner?

Get ready to win. This will give you a huge amount of strength and zeal, so necessary to win. Many people are the culprits of their personal troubles by self-programming for an unsuccessful outcome. You must firmly believe in yourself and know that you can complete any task brilliantly. It is better not to think at all than to think negatively.

Don't take games or situations too seriously where you want to win. After all, winning in itself will not bring you true happiness. But you shouldn’t take this or that competition too lightly. It is better to adhere to the principle of the golden mean. This will allow you to remain calm and will not disable your nervous system.

Constantly improve yourself, adding to your knowledge and skills. It is believed that it is almost impossible for the average person to achieve heights in several areas at once. Only selected geniuses are capable of this. If you do not consider yourself to be one of those people, then improve your skills in your chosen field. The number of winnings will increase significantly when you become a real professional.

Get a talisman that will bring you good luck. Many athletes, gamblers, politicians and businessmen have their own personal amulet. It could be a stone that matches the sign, a figurine, or some kind of trinket. The main thing is that you associate positive emotions with this thing.

Decide whether you are ready to adhere to all the rules or not. Some people see nothing wrong with cheating for the sake of a long-awaited victory, while others will never resort to lying. You must independently choose your tactics of behavior, revising them from time to time to achieve the best results.

Be sure to thoroughly analyze each game, your steps and the actions of your opponents. To always win, you must be completely absorbed in what you love.

Tip 3: How does a Japanese robot always win at rock-paper-scissors?

The unique Janken robot was created by Japanese scientists in the Ishigawa Oku laboratory at the University of Tokyo. This highly specialized mechanism is not only capable of playing a game of rock-paper-scissors with a person, but also winning. And always win, 100% of the time. The possibility of the robot losing is excluded.

The secret of this success lies in a specialized human hand tracking system, consisting of a high-speed video camera and a manipulator that performs the functions of a robotic hand. A digital camera takes pictures of a human hand every thousandth of a second and quickly analyzes its smallest movements. Based on the analysis, the processor is able to predict in advance what gesture a person will show and get ahead of him by instructing the manipulator to show the desired “figure.” The entire process, from analyzing the image to giving the robot’s hand the correct gesture, takes no more than 1 millisecond.

Of course, from a mathematical point of view, the probability of a person and a robot winning is 1:3, but in fact the robot is significantly ahead of the person and always wins, adjusting its answer to the gesture of the human hand. As a result, the person does not even notice the catch. The robot acts so quickly that it creates the illusion of synchronized action, that the robot is playing by the rules, and that it is constantly lucky. Attempts to deceive the mechanism by changing one symbol to another halfway lead to nothing - Janken timely calculates this enemy trick and issues its own symbol.

Visitors to the exhibition, seeing the robot for the first time and becoming acquainted with its capabilities, were often interested in: who will win this game if two robots compete? No one would actually win. Since the movement of the manipulator arm begins only after analyzing the movement of the opponent’s arm, both robots will simply wait for each other.

The goal of this project is a practical demonstration of the capabilities of innovative technologies, including those related to the collaboration of humans and machines. Programmers also showed that modern robotic mechanisms are capable of working in groups, constantly monitoring the work of other machines and people. At the same time, robots can be completely autonomous, have no communication channels with each other, have excellent observation and quick reactions.

  • What wins is stone or paper

There is no person who has not played the game “Rock, Paper, Scissors.” After all, she can not only take up time, but also resolve, for example, a dispute.

Meanwhile, not many people know that this game originated in China and later, in the 19th and 20th centuries, gained popularity in many countries around the world, including Russia. And at the beginning of the 21st century, the first championships in this “sport” with significant prize funds appeared.

To win this game you don’t need to be a psychic - you can read your opponent’s thoughts or program his actions, you just need to follow some rules.

1. Men tend to throw the "rock" first because it is perceived as strength and determination. Therefore, you can catch the strong half of humanity doing this; they get caught doing this quite often. Using this feature you can easily win by showing "paper". But remember that this trick will not work with experienced players.

2. If you are “lucky” to play with an experienced player, he is unlikely to show the “stone” for the first time - this is too obvious. Therefore, “scissors” are a fairly optimal option.

3. Tell your opponent what you are going to show and then... show what you said. Why? As long as you are not playing with someone who is unaware of your impudence, you can, by making your intentions known, get a favorable roll. For example, if you declare “rock”, then your opponent will not throw away “paper”, thinking that you will show “scissors”. This move can bring you a victory or a draw.

4. If your opponent throws scissors twice, then the chance that he will show them a third time is very small. Most likely, he will throw away the “paper” or “stone”. In this case, it would be advisable for you to show the “paper”.

5. During the second round, inexperienced players subconsciously show what could have defeated them in the past. For example, if your opponent was losing with “paper”, he will show “scissors”, then your move is “stone”. If the opponent threw out the “stone” the first time, then the second time it is advisable to show “scissors”: he will most likely decide to throw out the “paper”.

6. There are situations when you don’t know what to throw away. In this case, I advise you to show the “paper”. According to statistics, “scissors” are shown somewhat less often than anything else. However, not so long ago, British scientists found that the most winning strategy in the game is to show “scissors”. The fact is that most often the opponent subconsciously expects the “stone” gesture, which is why he shows “paper”.

Good game!

If you keep losing at tic-tac-toe or rock-paper-scissors, it may be because you don't know a winning strategy. Or your opponent knows it.

website will tell you about ways that will help you win in the 5 most popular games and gain the upper hand in disputes.

1. Tic Tac Toe

When making your first move, place your "X" in the corner. If your opponent responds by placing an “O” anywhere except the center square, then you can say that you have won. Place a cross in any of the free corners. The opponent, without thinking, will block your winning combination and stand between your crosses.

If after your first move the enemy occupied the center, then you can win in this case too.

Just place a cross in the corner diagonally from the one already occupied. Now, if the enemy occupies one of the free corners, then you win. Otherwise, it can be easily reduced to a draw.

2. "Monopoly"

"Monopoly"- a game in which a lot depends on your luck at the beginning and on your ability to negotiate in the middle of the game. But in order to significantly increase your chances of winning, it is important to adhere to certain rules.

    Buy railroads and don't buy utilities (electricity and water). Utility companies bring in little income already in the middle of the game, and transport will make you rich at the very beginning.

  1. Don't worry about hotels. After you have collected one of the color territories, build 3 houses as soon as possible. The 3rd house is the point where you find the best use for your money. They are easy to build and generate high income.
  2. Best territories- these are orange, light blue and red. They have a good location, they will bring you high income and help you win.

3. Arm wrestling

Even if you are facing an opponent who is superior in strength and weight, it is possible to defeat him if you use the correct technique of positioning your arms and body.

    Lean toward the table, step your right leg forward and place your right elbow on the table. If you are using your left hand, then advance your left leg.

  • Make sure that the distance between the forearm and the body is as small as possible. This way you can use not only your arm strength, but also your own body weight, this will give you an advantage.

    Lift your wrist up a little. This will cause your hand to drop down and your opponent's wrist to bend. This will make him uncomfortable and will help you strengthen your grip. If you can’t bend your wrist, just keep it straight.

    Now, when applying pressure, pull your opponent’s hand towards you, and you yourself come closer and lean with your shoulder. The important thing here is to keep your body and forearm close to each other.

  • For a decisive blow, turn your body a little and lean with your shoulder in the desired direction. Now all that remains is to drag the opponent towards you and press down. You won!

4. Billiards

Billiards- a game that requires skill, training and high concentration. Therefore, if an experienced opponent is playing against you, it will be very difficult to win. To increase your chances, stick to the basic rules.

    Don't let your opponent successfully break the pyramid. This is one of the basic rules. If you have an experienced opponent in front of you, then, having broken the pyramid, he can pocket all the balls at once, without allowing you to hit even once. So try to hit first.

  1. Take your time. It sounds cliché, but most people lose because they are in a hurry to hit the ball. Practice, aim, take a closer look. Don't mind if you are being rushed. Patience is important in this game.
  2. Hit it right. If your ball deviates from the intended trajectory, then you are hitting the ball off center. Place the cue so that it coincides with the line of the future strike. If you are right-handed, then place your right leg perpendicular to this line, your left leg forward. The shoulder, hip, elbow and chin should be in the same plane.

5. Rock, Paper, Scissors

Many people believe that the game of rock, paper, scissors consists of randomness. In fact, it will be easy for you to win if you know some psychological tricks.

Researchers from Zhejiang University conducted a huge number of experiments, the results of which showed some patterns.

    Most people always start with a rock. Moreover, men are many times more likely than women. However, many people do not throw the same sign 3 times in a row. So throw away the “paper” 3 times in a row and you win.

  • People don't like to be predictable. If your opponent throws a “stone” 2 times in a row, then in most cases the next sign will be “scissors”.
  • Watch your opponent's fingers- they will tell you what move the enemy is going to make. All fingers are tense - “stone”. All fingers are relaxed - “paper”. Only two fingers are tense - “scissors”.

God only knows how many controversial situations in childhood were resolved by playing “Rock, Paper, Scissors.” Why are there kids, there are a lot of grown-up kids who find an easy way out in a matter of seconds and a discarded sign. So what is hidden behind the simple throwing of fingers: chance or a proven strategy? Scientists firmly know the answer and give their winning recipe.

Just recently, a team of Chinese researchers from Zhejiang University notified the world about the bold findings of their psychological tests. Scientists conducted 5 experimental cycles from December 2010 to March this year. Each cycle included 12 sessions with 6 participants. In total, the total number of subjects reached 360 people. The gender ratio was 217:143 with a female preponderance (simply girls were more active in signing up). A student or graduate student could participate in the study only once. People were out of sight of each other, in front of monitor screens. This eliminated verbal and visual contact. Each participant spent from one and a half to two hours playing 300 games with a random opponent. The incentive to win was a small monetary reward for each round won.

So what do you need to know to win? After observing a huge number of "battles", scientists found that a player who defeated his opponent in the current game was more likely to repeat his actions in the next round, and less likely to change anything.

On the other hand, if a player loses two or more times in a row, he will stop showing the bad hand and try to break the very sign that just allowed his opponent to beat him.

Thus, if player A was on a losing streak, and player B had just thrown away the scissors, thereby cutting A's paper, then A would likely have thrown a stone, which would have a decent chance of winning, since B would likely stick the same winning tactics. The psychology of behavior is simple: if you win, you don’t change; if you lose, you switch.

Lost? Discard the sign that beats your opponent's last winning sign.

Did you win? Don't keep showing the same sign, instead throw out your losing opponent's last hand.

Still not completely clear? Here are some winning strategies that will help you stay invincible:

If you won the last game...

If you lost the last game (and your opponent is not aware of this technique)…

  • ...after throwing away the stone, move on to scissors in the next fight
  • ...throwing out the scissors, move on to paper in the next fight
  • ...throwing away the paper, move on to the stone in the next fight

If you lost the last game (and your opponent is aware of this technique)…

  • ...throw away the stone, go to the paper in the next fight
  • ...throwing away the scissors, move on to the stone in the next fight
  • ...throwing away the paper, move on to the scissors in the next fight

You can familiarize yourself in more detail with the research methodology provided by Chinese scientists to the public. Of course, it is written in English and contains layouts and formulas that are difficult to understand for people far from mathematics.

And in conclusion, I will add that the blame for losing cars, houses and wives in “rock, paper, scissors”, first of all, should be placed on your own passion, and not on the Chinese minds and the author of these lines.

In a game of rock-paper-scissors, two opponents shake their hands and make random gestures, and each has the same probability of winning, losing, or being tied. It seems that luck plays a role here, not skill. And indeed, if people could act 100% arbitrarily, then everyone would win with the same frequency.

But there is one problem: people absolutely cannot act arbitrarily.

All our claims to unpredictability have failed again. A couple of recent studies have delved into the patterns that people typically play rock-paper-scissors (and why they follow them). Knowing them, you will always be among the winners.

Graham Walker, a veteran of the game and 5-time organizer of the World Rock-Paper-Scissors Championship, argues that there are two ways to win. The first is to limit the opponent's capabilities - for example, you can influence the opponent not to play with paper. The second way is to force a predictable move. In both cases, as Walker wrote on his IPOB World Community website, “the point is to subtly manipulate your opponent.”

Invincible stone

Those two dominance strategies can be put into practice by starting simple. Expert players have noticed that inexperienced opponents always tend to play with a stone. Walker believes that this move seems stronger to them. Keeping this in mind, you can simply play with paper in the first draws for an easy win.

It is worth remembering the stone when playing with more experienced players. They won't start their game with a rock - that's obvious - so walk with scissors. Such a move will cut the paper or give you a draw.

Double punch

If your opponent makes two identical moves in a row, you can almost certainly expect that he will not repeat the move three times. “People hate being predictable, and walking the same way three times is a sure sign of predictability,” Walker writes.

By using this feature, you are guaranteed to either win or advance to the next round. If you see your opponent move scissors twice in a row, his next move will be either rock or paper. If you play paper, you will either beat the stone or draw.

Thinking tricks

As a Jedi, you can influence your opponent's next move through the power of suggestion. When discussing a game, for example, constantly gesture as you would like to make him walk next time. “Believe it or not, even when people aren't paying attention, their subconscious is working to notice your cues, and this often often determines their next move,” Walker writes.

This tendency to imitate another person's actions works great. A recent study on decision making in rock-paper-scissors, published in the July 2011 journal Proceedings of the Royal Society B, found that players often imitate their opponents' final moves. This happens involuntarily.

Announcing the next move before the turn begins is also an effective mental trick. But it only works once. Walker explains: “If you tell your opponent you're going to play paper, your opponent will think you're bluffing. Subconsciously, he will not choose the move with scissors (which will break the paper), and will choose the move with stone or paper. If you perform as well as you promised, you will earn a win or a draw.”

Don't expect retribution

According to Walker, the opponent will always try to compensate for his loss by repeating the move that won the last round. If he loses by hitting a stone, for example, then his next move will most likely be paper. Knowing this, you can successfully respond to your opponent.

Funny, monkeys exhibit the same pattern of behavior. In a study published in the May 2011 journal Neuron, Yale University researchers trained rhesus monkeys to play rock-paper-scissors. Animals reacted to loss in the same way as people. The monkeys repeated the last winning code. This suggests that monkeys, like humans, are able to analyze past results and also think that a second move will bring them a different, opposite result.

People can calculate the logic of their actions one step ahead by imagining what their opponents are imagining.

Hit below the belt

There is one more trick - if the fairness of victory is not as important to you as the victory itself. Walker advises: “When you ask someone to play, don't talk about how many rounds you want to play. Play the first match and if you win, then call it a day. If you lose, start the “next” round immediately. No doubt you will hear protests from your opponent, but stand your ground because you cannot determine the winner from just one game.” It may not be fair, but it’s so smart.

Didn’t you realize there was such an abundance of strategies in a simple game of rock-paper-scissors? The rules of the game itself may be simple, but the human mind is much more complex.
