The city of games is probably surrounded by iron walls. Xiaoxue: What they saw was an upside-down metal bowl. However, this metal bowl is too huge, covering a radius of thousands of kilometers. They will be sent to the inside of the giant bowl, and I am afraid that they will never think of it for the rest of their lives. Xiaoxue was still immersed in her pain, and Zuo Zhan and Brother Orangutan were already terrified when they saw such a building. "There is no daylight", "there is nowhere to escape", their minds are full of similar thoughts. They were right, this lonely city, since its construction, no one has been able to escape. There are many people who want to break through the level, and it is said that the idea has just sprouted, and not only the sun and moon the next day, but also the air of the next day.

The entrance door has the words "Absolute Prison" written on it, and it seems that this is the name of this "inverted metal bowl". After passing through one gate, they saw another. After the original gate was closed, another gate was quickly opened. The aim is to prevent prisoners from escaping when new prisoners enter. For security reasons, the key to the gate is also kept by the twelve guards general Splash Monkey himself. When Xiaoxue and the others came to the Absolute Prison, the outer door opened first, and when they entered the Absolute Prison and the outer door was completely closed, the inner door slowly opened. This is the only gap in the absolute prison, but unfortunately, there are no loopholes here at all, and Xiaoxue and they have no chance to escape except for the legendary breakthrough.

Walk through the inner door and start their gaming career.

"Welcome to the City of Games," said the guide, "the rules here are very simple, as a prisoner, each of you will enter the castle with a negative score, starting with a score of -5. You will receive one point for each level you win, and you will deduct the points specified in the rules for your defeat. When your score reaches zero, you will be able to gain freedom and be exempted from the Empire. However, if your cumulative score is less than or equal to -8, you will be disqualified for life. In other words, if you're lucky, you only need to win 5 points in a row and you'll be able to leave this castle of fun and games - a pity that no one wants to leave after all these years. Except for the first and second levels, which are mandatory levels, you can automatically choose to challenge or not to challenge the other links, and the time of the challenge is also determined by you. Of course, the first and second levels are actually points to give, so if you are clever enough to actually enter the game city, in fact, you only need to win three levels in a row before you can be free. It's a pity that no one has been able to pass the third level so far. ”

The guide paused slightly, gave Xiaoxue time to ask questions, and seeing that they didn't speak, he continued, "If there are no problems with the three of you, then we will start the first level of the game." Of course, the first level is an individual game where three people need to be separated. In front of the three are three separate rooms. Ask the three of you to choose your favorite room and play the game. Of course, the door to the room will be locked after the three enter the room, and the door will not open until the three have finished the race. ”

"It's broken. As soon as Zuo Zhan entered the room and understood the rules of the game, he shouted. He hoped that there would be a response from the left and right rooms, but unfortunately there was none. He chose the middle room, originally hoping to notify Xiaoxue and the orangutan brother when he found something strange or had something happened temporarily. What he didn't expect was that these three rooms, which didn't look good, were not only sturdy and safe, but also ridiculously good soundproofing, I am afraid that the walls were made of steel plates, and the steel plates were filled with soundproof sponges and other substances.

Zuo Zhan secretly complained, because he knew the trick of this game, but I was afraid that Xiaoxue and the orangutan brother didn't know anything and played the game in a daze.

The rules of the game are very simple. In a box, there are a hundred stones, and the prisoner and the examiner take turns to take one to seven quantities from the box. If the prisoner finally finishes the stone in the box, the prisoner wins and gets one point, and if the examiner finally gets the stone, the prisoner loses and gets one minus one point. The prisoner takes the lead and has five minutes to think about it before the game starts.

Zuo Zhan thought that in order to achieve victory, then after the examiner finally took the stones, the number of stones must be between one and seven, and to force such a thing to happen reliably, then after he took the stones for the penultimate time, the number of stones left could only be eight. Because if the number of stones left is less than eight, that is, between one and seven, then the examiner will be able to take the remaining stones, and the prisoner will lose. If the number of stones is greater than eight and less than sixteen, the examiner is able to take a certain number of stones, so that the number of stones left is exactly eight, and after forcing the prisoner to take the stones, the number of stones is exactly between one and seven, and the prisoner is still defeated. Therefore, to ensure victory, after taking the stones for the penultimate time, the left battle must make sure that the number of stones is exactly equal to eight.

However, with between a hundred and eight rounds of gambling going through, it seems unlikely that such a thing would happen reliably. After all, the examiner is a veteran who has experienced many games, and he is only the first time to come into contact with such a game.

But Zuo Zhan soon found out that in order for himself to take the stones for the penultimate time, the number of stones was exactly eight, and for such a thing to happen reliably, the number of stones must be equal to sixteen after he took the stones for the third time. Because if the number of stones is less than sixteen, the examiner will be able to pass his link of extraction, so that after he has taken the stones, the number of stones left is equal to eight. If the number of stones is higher than sixteen and less than twenty-four, the examiner can make the number of stones remaining equal to exactly sixteen, and after the prisoner has taken the stones between one and seven, the remaining stones are between nine and fifteen, and it is the examiner's turn to take the stones, and he can make the number of remaining stones equal to exactly eight. By the foregoing reasoning, whoever has eight stones left will be able to reliably win, and after the prisoner takes the stones for the third time, the number of stones left is greater than and less than sixteen, and in both cases, the prisoner will lose. However, if the prisoner makes the number of stones equal to sixteen, just as the previous examiner makes the number of stones equal to sixteen, the prisoner can reliably take the number of stones in the next step, so that the number of remaining stones is equal to eight, and thus win the victory.

Soon, Zuo Zhan found out that the other key numbers were 24 and 32...... It is not difficult to find that these are multiples of eight. Zuo Zhan also discovered this rule: whoever takes the stones, and the number of stones left is a multiple of eight, will be able to win.

Therefore, after five minutes of thinking time, Zuo Zhan took four stones in the first hand, so that the number of remaining stones was equal to ninety-six, and in the second hand, he made the number of remaining stones equal to a multiple of eight - eighty-eight. The examiner knew that Zuo Zhan had seen the doorway, and he admitted defeat after winning the second hand in Zuo Zhan. The game originally required more than a dozen rounds, and the left side was divided from the beginning of the victory.
