Sakaki lied.

There is no sure-win strategy in gambling.

Any bet has the possibility of some changes before the final result is revealed.

That kind of game in which "the outcome is firmly controlled by a certain party" cannot be called gambling at all.

For example, "online game unboxing/package" is purely a repetitive event based on data algorithms. The probability is set entirely by the operator. The seemingly random results are just to create the illusion that "luck exists" for players.

Although some slot machine gambling machines also use this principle, slot machines are public and different people can sit on the same machine to play, so there are still a very small number of players who can benefit from this kind of game where the operator is bound to make a profit. Get a piece of the pie; but online game accounts... are private, and the probability events involved in each account are a pseudo-game between the player who owns the account and the operator. To put it bluntly, it is a unilateral squeeze.

Real gambling should be a two-way game, and either party has the possibility of winning or losing.

Right now, Sakaki's horse racing strategy is no exception, and there is a risk of failure.

Of course, although his method is not a "guaranteed victory", the probability of victory is indeed very high.

This method is called - "Double Betting Method".

Take the event that Ryunosuke randomly attended at this moment as an example... This is a game that took place at the local "Central Racecourse" in Sakuranofu. Judging from the scene at the scene, the time point should be in the twentieth century. During this period, There are usually 12 races held at Central Racecourse every day.

The method of double betting is as follows: in the first game, bet 100 yuan (because the currency unit has been converted to a unified value, it is expressed as "block" here) on the "second favorite". If you win , no more betting on this day. If you don't win, you will bet on the "second favorite" with double the amount of 200 yuan in the next game (the second game)...Similarly, if you win, you will no longer bet on that day. If you don't win, you will bet on the "second favorite" in the next game. 400 yuan bet.

Repeat the same operation until you hit the mark, that is, "win money."

At the Central Racecourse, the winning rate of the second favorite is 18%. A rough calculation shows that in 12 races a day, an average of two "second favorites" will win; in addition, under "normal circumstances", the "second favorite" will win The odds are bound to be more than twice, so using this method, you will win money no matter which game you buy.

At first glance, this sounds like a "sure-win" method.

But is this really the case?

Obviously not.

There are two problems with this method: first, funding.

Starting from the first game of 100 yuan, the bet amount will be doubled for each game. In this way, when you buy the tenth game, the next bet will be 51,200 yuan. If you buy the last game of the day, the next bet will be 204,800 yuan. , the vast majority of people who go to the racetrack cannot afford that much money.

Second, the winning rate.

Although the winning rate of the "second favorite" is 18%, this probability also represents - the probability of "all the second favorites losing on the same day" is (1-0.18)^12≈0.0924=9.24%, that is, every 11 This happens once on race day.

Some people may say that if you have sufficient funds, it doesn't matter if you lose everything in one day, because you can continue to use the "double betting method" on the second day, that is, starting from the first game of the next day, you will bet 409,600. This way, it is still a "sure-win method".

Unfortunately... this is still wrong.

When the bet exceeds five million (i.e. the fifth game of the next day), you have created an "abnormal situation" yourself, because your bet amount will cause the odds to change significantly, making the original "time" The "favorite" will become a "big favorite", and its winning odds will therefore drop to less than twice...At this time, even if you win, you will not be able to get back your money due to the reduction in payouts.

This is gambling.

However, in "virtual horse betting", the situation is different.

First of all, Ryunosuke's starting capital is very sufficient; the six million virtual coins he received after putting three point cards into the instrument can be used as a double bet until the third game of the next day. And after this miss, there is still more than two million yuan left.

Secondly, the amount of "virtual horse betting" bets will not affect the "odds"... because the games they are sitting here watching have "happened in the past", no matter how much they bet here The money is just gambling virtual currency with the computer in front of you. Neither the results nor the odds of the games that have already happened will be changed.

Under this premise, the feasibility of the "double bet method" has naturally improved a lot.

In fact, as long as you "read" the rules at the door, you will find that the "double betting method" is most likely the "correct answer" to the "virtual horse racing" project as determined by the organizer.

For example, "At the end of each game, if the player makes a profit in that game, the next game will jump to another event at another point in time; if the player does not make a profit in that game, the player will jump to another event at the current time point. The event will continue." This article is simply designed to cooperate with the double betting method. To put it bluntly... if you win, you will directly "change the day" and reset the probability. If you lose, you will continue the game in chronological order.

There is also the section about checking various information and odds before the game, which is equivalent to helping players confirm who the "big favorite" and "second favorite" are for each game.

If nothing else, the last two rules that set the "maximum winnings" for players are probably to prevent someone from seeing through the "hacking method" of this game and then unlimited points.

To sum up, it is not difficult to see that... Sakaki had already thought of this when he read the rules at the door; he only used the words "a sure-win strategy" to deceive Ryunosuke when he was very confident. Come in.

Of course, there is no need for Sakaki to fully explain the truth to Ryuunosuke; this is also a rule that "experts" understand - unless it is absolutely necessary, they should only say "eight points" to laymen at most.

…………

Subsequently, the development of things also verified Sakaki's guess.

The "virtual horse betting" that claims to "randomly select and replay different horse racing days around the world over the past two hundred years" actually replays all events in which "at least one of the 'second favorites' wins that day."

In other words, the "double betting method" is indeed the "correct solution" set by the organizer; as long as you decipher the hidden tips in the rules, conduct a thorough calculation of the probability and odds of horse racing, and then pass the minimum bet Observing the way for a while, anyone has a chance to crack the secret.

It's a pity... there are still people who lost all their money on this project; it can only be said that the "experts" hired by these people are too weak to crack a game of this difficulty. They will undoubtedly lose when encountering a confrontational project. Worse.

But Ryunosuke was different. He had adopted the double betting method from the very beginning, so naturally he would not lose.

After a short period of observation, Sakaki also discovered the rule that "no matter where you go randomly, no matter which horse racing day it is, one of the twelve races will be the second favorite." Therefore, he asked Ryuunosuke to increase the starting amount of bets after each "win and jump time point". Moreover, he no longer looked at any pre-match information and the game process except the odds, and just quickly Buy the next favorite, then skip to the settlement stage to see the results.

This approach greatly increased the efficiency of winning money; in just half an hour, their net income from virtual currency exceeded 18 million.

At this time, the game will automatically end.

The coin outlet under the coin slot opened smoothly, and twelve points cards were spit out, which were neatly stacked there; a man in a black suit also came over in time and asked these people to vacate their seats.

When leaving the "virtual horse betting" game cabin, Ryunosuke's face was full of joy, and his last suspicion about Sakaki had also disappeared - he thought he was just a man who could kill everyone in mahjong, but it turned out that he played this kind of gambling against the banker. Yugi is also a good player; and this also caused Ryunosuke's mentality towards becoming a "winner"... to undergo a subtle change.

…………

At the same moment, the "ESP Card Induction Game" was outside the cabin door.

A muscular Latino man walked out and played with the eight points cards he had just won with a proud look on his face.

"Oh~ Baby, you are really amazing. You helped me win so much in just a short time."

While he was talking, a well-dressed Latin beauty with a hot figure also came to the deck.

"Ha... It's a small trick, but Darling, your cooperation is really good, which saved me a lot of trouble." This beauty is the man's lover, and she is also an "expert" with superb gambling skills; so , she is both the man’s female companion and his gaming partner.

Just as the two were flirting, suddenly, another person's voice came from not far away: "'Mandala' is indeed well-deserved..."

As soon as he spoke, the beauty's expression changed, becoming cold and cruel.

"Who are you?" The woman known as Mandala immediately turned her head and asked angrily.

She does have reason to be angry, because there are rules among "experts" - some people's nicknames can be mentioned, and some people's nicknames must not be mentioned... "Mandala" is a person who should not be mentioned in front of "laymen" Names mentioned.

Seeing Mandala's reaction, the two bodyguards following the Latino man who had just walked out of the game cabin consciously stepped forward and surrounded the interlocutor.

"Wow~ wow~" The person who spoke to him was a rather thin white man. He was only about 1.6 meters tall and weighed less than 100 pounds. He was wearing a small brown suit that looked tailor-made. "Don't be nervous, gentlemen..." Seeing the two burly men blocking the way, he quickly opened his hands and raised them to his shoulders, making a gesture similar to surrender, "I'm just representing my employer... I'm here to follow you. Say a few words to your boss."

"Who is your employer?" The Latino man had already walked to Mandala and put his arms around the beautiful woman's slender waist. He didn't seem to care much about this little man who suddenly appeared, but since If the other party makes his woman angry, he will naturally not look good on her.

"He is not acquainted with you, Mr. Jimenez." The little man said with a smile, "But... your father had a close relationship with him during his lifetime, and you must have heard some rumors about him, and ...His name." Having said this, he slowly reached into his coat pocket and took out a small white stone.

Although it is a stone, its surface is as shiny and round as jade. At first glance, you might think it is an artificial artifact, but it is actually a natural creation.

As soon as Jimenez saw the stone, his expression changed. The originally relaxed look disappeared from his face and was replaced by a bit of nervousness.

"You..." Jimenez let go of the female companion in his arms, took two steps forward, and looked at the little man again, "...are you from 'Juizun'?"

"I don't dare take it seriously." The little man shrugged and smiled, "I'm just an errand boy."

"Master Jue, do you have something to tell me?" Jimenez asked immediately.

"Well, actually just one sentence..." When the little man said this, there was a chill in his smile and tone, "Get out of this ship while you still have your life."
