It’s past midnight and the “Supreme Game” is still in full swing.

No matter they are dignitaries accustomed to nightlife or gamblers who have been surviving in the dark all year round, they will not feel tired at this time; on the contrary, this is the time when their physical and mental excitement reaches its peak.

At this moment, Ryunosuke and his party were staying in a game cabin called "Music Note Roulette".

There are two differences between this game and ordinary roulette: first, the ivory balls used in this game are thrown mechanically rather than manually, and the dealer is only responsible for maintaining order on the table and settling chips; secondly, in each round, Before placing bets, a computer connected to the roulette table plays a random melody, ranging from two or three seconds to seven or eight seconds in length.

Although it is not stated in the rules, anyone can see... This setting clearly shows that the result of "Note Roulette" is determined by the computer, and the result of each round will be determined by the computer. There are hints in the melody played in advance; as long as you can decipher the connection between the melody and the result, the game is not difficult.

So... not surprisingly, this project also sets a "maximum winnings" to prevent players who have cracked the secret from earning unlimited points here.

Sakaki is not very good at this game; as a professional gambler who has been "employed" since middle school, "music" is definitely a blind spot in his knowledge. Even if he knows some basics, it is not enough to help him crack this game. puzzle.

However, Ah Xiu seemed to know a lot about this and was very good at it. When he saw a project with the word "note" in its name, he offered to take a look and expressed that he had encountered something related to it. When solving puzzles, he can explain some musical knowledge to everyone.

Anyway, the roulette scene is relatively free. There is no requirement that you have to place a bet in every round. You can just stand by and watch. If you don't see anything useful in the end, the worst possible outcome is to leave.

So Ryuzosuke followed Axiu's suggestion and came to this cabin.

Although Sakaki doesn't know much about music theory, he knows everything about roulette.

Roulette is a form of gambling that is very beneficial to the banker. Putting aside the factor of cheating, this is a pure competition of luck without any skills at all, so the winning rate of both parties can be known by simple probability calculation.

Take the standard roulette wheel with 36 numbers, which can bet on red and black, odd or even, and several segments, as an example. In addition to the numbers 1 to 36, there are two additional numbers "0" and "00" on the roulette wheel, a total of 38 , the probability of drawing any number is 1/38; therefore the banker’s expected value is 1×1/38+1×1/38+1×35/38-35×1/38=2/38=1/19≈ 0.0526; that is to say, every time a customer bets 10,000 yuan here, he will lose 526 of it. The longer the gambling goes on, the more this amount accumulates.

The probability that a customer only bets on one number and wins money is only 1 in 38, which rarely happens; even if it does happen... as long as there are enough customers on the roulette table and they play well Long enough, the banker's overall advantage remains unchanged.

It's just that...the vast majority of guests don't calculate these things; people who gamble with the mentality of "just having fun" and "trying their luck" often only see those "lucky people" who accidentally win. , but fail to see the big picture.

Professional gamblers are different.

More than 90% of people in this industry participate in every gamble with the idea of ​​"never losing"; they don't have the pleasure of "going all-in" because the stake is their life. , running out of money is like death to them. Except for a very small number of lunatics, no one would find any joy in risking their lives on the table.

Casual guests can complain about "what a bad luck" after losing all their money, and then go back silently.

But gamblers... have no place to "go back" to, the gambling table is where they live.

In order to survive, they must force themselves to do things that ordinary people cannot do; such as memory, calculation, and deduction, which are the basic abilities applicable to all gamblers...not even the probabilities in the "game of chance" Those who come out no longer need to talk about assessing risks, catching luck, and winning.

There is no doubt that Sakaki is outstanding in these three aspects. With his knowledge of roulette and constant communication with Axiu... After observing for fifteen minutes, Sakaki and Axiu left. He walked into the crowded gambling table and went to the corner to whisper for a while.

After a while, the two looked at each other and smiled, showing a relaxed expression.

Upon seeing this, Ryunosuke understood at that moment...the two people had discovered something, and had even come to a conclusion.

Sure enough, Sakaki immediately came to Ryunosuke and quietly told him the rules of the game - to put it bluntly, this is a project of "reasoning" and "quick calculation". After deducing the algorithm, he can solve it in one go .

The hint about the algorithm is actually hidden in the name of the game; why is this project called "Musical Roulette" and not "Musical Roulette" or "Melody Roulette"? No matter how you look at it, using the concept of musical notes to describe this game is a bit inconsistent, right?

This violation point is to make players notice... "notes" are the key to this game.

Everyone knows that the melody before placing a bet hints at the outcome of the current round, but how to convert the melody into numbers? Others have naturally tried to solve it, such as replacing the scale CDEFGAB with 3456712 or 1234567 respectively, and then doing some conversions with the number of seconds the melody lasts; or calculating the difference between scales, the number of whole tones and semitones, etc.

Unfortunately...that's not right.

The correct solution is to calculate based on the type of "note", that is, rely on "hearing" and "music theory knowledge" to hear what fraction of notes appear in the melody, and then multiply them by the corresponding scale, and finally Then add up each digit.

Of course, just thinking about this level is still wrong...the answer is not that simple.

Assume that if a quarter note encounters a scale such as 3 or 7, a fraction will appear after multiplication. The occurrence of such a value in a calculation where the answer must be an integer indicates that there is an error in the direction of solving the problem.

At this point, Sakaki and Axiu were stuck for a long time. In the end, Axiu thought about the melody he had heard before and finally solved the mystery - don't think of the scale as 1 to 7, but think of it as If it is a key on the piano, it is fine; for example, the last key on the piano is called do. If you guess based on the scale, it should be 1 or 3, but here, it should be regarded as "88" .

Axiu thought about this pattern many times and realized that all the notes that appeared in the melody were the "white keys" on the piano, and they were all even numbers among the eighty-eight digits. That's when Axiu came up with this model.

After discovering the correct idea, things will be easier to handle.

In the following rounds, every time the melody sounded, Axiu, who was responsible for "listening", immediately reported the scale and the numbers referred to by the notes, while Sakaki immediately converted all the numbers into a final result. This level of mental arithmetic can even be done by elementary school students. For them, it can be done in a matter of seconds.

As a result, they guessed the answer correctly for four consecutive rounds.

However, in these four rounds, they were just experimenting and did not let Ryunosuke take money to place bets; because according to their puzzle-solving ideas, the three numbers "0", "00" and "1" were all It is impossible to appear, and the probability of 2 to 5 appearing is also very small... This is a doubtful point; this means that there is something in the puzzle that they have not completely seen through, that is - "risk".

Therefore, Sakaki and Axiu made further observations. Finally, after guessing correctly for the sixth time in a row, an "abnormal melody" appeared, that is, a melody that "cannot get an integer using the cracking method they thought of."

When this abnormal melody appeared, the number "0" was drawn in that round.

After knowing this, they were relieved; they no longer had to solve the melody formulas of the three numbers 0, 00 and 1. They only needed to know that there would be signs when such abnormal numbers appeared.

In the next round, a normal melody sounded. At Sakaki's signal, Ryunosuke directly placed all the stack of chips that he had exchanged at the door (note roulette is played by exchanging points for chips) on a single number. , his gambling capital doubled by 36 times in one fell swoop... Because he had never bet before, that is, he had never lost a dollar... Therefore, there is no doubt that this round of betting made his profit exceed this The maximum amount of money the project can win.

Until he left the game cabin, Ryunosuke still had only a partial understanding of the theory Sakaki and Hide said, but it didn't matter to him; now, he had 200% trust in Sakaki, and he He firmly believes that the man next to him is the strongest gambler. Even if Sakaki asks him to bet all his points on a certain project, he will do it without hesitation.

…………

It's two o'clock in the morning. Taking into account seasonal factors, there are still more than three hours before dawn.

The highest game is also becoming more and more intense.

Those who have lost everything and are sitting on the sidelines, those who still have hope and are struggling, those who think they can win and are making the final push... The closer we get to the "end", the more attractive the "gamble" becomes. People can't help themselves.

By this time, most people have seen through... Each of those projects that are betting against the banker has a "strategy"; in fact, some people have already taken advantage of this to launch some actions.

For example, you can use the strategy method you have mastered for a certain event to exchange it with someone else's strategy method for another event, or you can use the "method" to directly exchange for points cards.

Take "virtual horse racing" as an example. You can propose that someone exchange a number of point cards (less than or equal to the maximum value that can be won for the project) in exchange for a "strategy method"; if the other party agrees, you can do it at almost zero cost. In this situation, you can easily get points cards. Although the opponent lost a few points cards first, after mastering the strategy, you can quickly win more points, and after you win, you can also use the same method. If you sell it to others... you will still make money.

But among them, there are many points to be wary of: What if someone uses fake strategies to deceive you? Or the other party himself knows little about it, or even deliberately withholds key information from you to trick you... Then you may suffer a huge loss.

To take a step back, the person who can sell you information means that he has already obtained points ahead of you in this project. If you give him points again... even if he does not come to lie to you, you and his The gap will only grow wider.

To sum up, those who are still playing "games with upper limits and against the dealer" basically have no chance of winning.

Players who really have a chance to win the final victory have now accumulated enough "capital", and they have gathered in the game cabins of those "confrontation projects"... and started a good show of embezzling and killing each other.

Ryunosuke and the others finally arrived at the "Mahjong"-themed game cabin, ready to show off their talents.

Things in this world are such coincidences... Just as they walked to the door of the cabin, Eric, his two bodyguards, and the "Star County Gambling King" Hopkins also arrived.

It can be said that enemies can meet each other even though they are thousands of miles apart, but true love can never meet across the street.

Ryunosuke and Eric didn't even need to speak. As soon as they entered the cabin, they sat across from each other at the same table and glared at each other; the smell of gunpowder between the two... seemed to be able to blow up the entire ship. .

A few seconds later, a man in a black suit quickly walked over and said, "You two, do you want to join the game?"

"Ah...of course." Ryuzosuke responded.

"Ha..." Eric lit a cigar for himself and sneered, "That's right."

"Yes." The black suit nodded, "Although it is written in the rules at the door, I need to emphasize again that in this game, I am only a circumstantial witness. For situations like 'Out of Thousand', even if I see through it , I have no obligation to point out that if you want to 'seize the current situation', you must do it yourself."

"To put it simply..." At this time, Sakaki continued in his ruffian tone, "Everyone relies on their own abilities, and those who are fooled... can only blame themselves for being stupid." As he spoke, he was already in the dragon's house. He sat down on the left side of Jie.

"Hehehe..." On the other side, Hopkins also wore his scheming smile and sat on Eric's left hand side, "This 'winner' guy... you seem to be quite confident. .”

"'Confidence'?" Sakaki repeated the two words and laughed dryly, "Ha...it doesn't matter whether you have that kind of thing or not." He said, gently touching the table with his palm, "If you want to win... It depends on 'strength'."
