Xia Yu smiled slightly, didn't say anything, but Fuxue was watching from the side, but he was very concerned.

I saw that the professor carefully took out a moon spirit stone from the money bag and stuffed it in, and the number ten was immediately displayed on the Xuanlong machine.

Xia Yu was surprised that he could still identify the face value of the currency.

The professor began to play like this, and he began to bet on one at a time, on the reverse scale, and then gradually increased the stakes, sometimes a sun and a plum, sometimes a moon and an orchid, but each time he must bet an additional reverse scale.

Every time the result is out, whether he hits or misses, he has to take out the black hardcover notebook he has with him, write down a set of numbers on it, and so on seven or eight times.

There was a sudden knock knock sound in the Xuanlong machine, this sound was completely different from the previous times, Xia Yu knew that there was something wrong, and when he turned to the reverse scales, the dragon's eyes suddenly lit up, and the dragon scales on his body began to move irregularly.

First hit a plum blossom, then hit a sun, then hit another plum blossom, a dragon's mouth, and began to spit out spirit stones frantically.

Blowing Snow was stupid when he watched from the sidelines, "Oh, oops, traveler, look at it." ”

In fact, there are not many, probably only more than a hundred spirit stones, but the movement is big enough, and it looks amazing.

The professor didn't seem surprised by this result, and unhurriedly recorded something in the notebook, so he put the spit out spirit stone into his pocket, and didn't continue to gamble, nodding at Xia Yu and leaving.

As soon as he left, Fuxue immediately sat up, and raised his hand to stuff the spirit stone, but Xia Yu hurriedly pulled her up.

Blowing Snow was a little confused, "What's wrong, I think this machine is very good, he just hit so much, hurry up and don't let people take the lead." ”

Xia Yu shook his head, "If you want to play with this machine, I guarantee that you will lose to death." ”

"What do you mean?"

"Don't you think it's a little strange, why did the professor leave when he won so much?"

Blowing Snow touched her head, as if it was really a little strange.

Xia Yu pointed to the professor not far away, "Take a look." ”

Blowing Snow looked at it for a while, and now she also saw that there was a problem.

The professor seems to like to pick the kind of machine that can't be bet on no matter how he bets, but those who have won the jackpot, he doesn't touch it, he watches from the sidelines, every time the person who plays wins, he immediately turns around and leaves, but if he doesn't win, he has been watching from the sidelines, until someone has been losing too much and getting up and leaving, the professor immediately sat down and continued to play.

"Gee, did the professor find any patterns?"

Xia Yuxin said that of course, in fact, he also probably mastered the rules of this Xuanlong machine, which should be similar to a slot machine.

"Do you know slot machines?"

Fuyuki nodded, "You know, what's wrong?" ”

"The slot machine thing,It seems that the result is random,In fact, it is pseudo-random,It has a set feedback mechanism,Generally speaking,If it is not too black,The feedback rate of the slot machine will be set at about 90%,That is, eat 100 yuan,Will spit out 90 yuan。

In this way, as a banker, you are sure to make a profit, and if you keep playing on a machine, then you will definitely lose, because the odds are set and it is never possible to win more than the return rate.

But generally speaking, the players on a machine are not fixed, if someone loses 50 yuan and leaves, at this time you only need to feed another 50 yuan in, you can trigger the feedback mechanism, spit out 90 yuan at a time, and you can earn 40 yuan inside and out.

Therefore, when playing slot machines, don't touch the kind of people who have just won the jackpot, because you don't know when you want to trigger the next feedback, but the kind of person in front of you who has lost a lot, and it is easy to pick up the leak at this time.

In jargon, it's called a cushion knife, and many pseudo-random online games will use this design. ”

Xia Yu used to be a professional player, and he also studied some games that draw cards and upgrade equipment, so he knows a little bit.

Blowing Snow didn't seem to understand it, and after thinking for a while before she understood, she said in surprise, "Then wouldn't it be a sure win if you get this way?" ”

Xia Yu shook his head, "It's not that simple, because the point of this feedback mechanism is difficult to master, and you can't know how much it eats and will give you back."

And the return rate is not guaranteed, in case the dealer is a black heart, the return rate is set to be particularly low, although the probability of this possibility is not very large, but also have to be guarded against. ”

But in fact, there is another reason why Xia Yu didn't say it, the bet of this Xuanlong machine is too small, and you can't win much, the large number of this thing feels like it's for some casual players to play casually, if you want to win a lot of money, you have to have a bigger gamble.

Blowing Snow was a little moved, "I decided to give it a try, thank you, Traveler, don't you say I really can't figure it out, do you want to play together?" ”

Xia Yu shook his head, "No, I'm not too interested in this kind of mechanic game." ”

What Xia Yu is looking for is a game that relies purely on luck, and only in this way can he maximize his abilities.

And it's better to have a bigger bet.

Seeing that Blowing Snow was rushing to pick up the leak, Xia Yu continued to wander around.

After passing through the rows of Xuanlong machines, walking around, I saw the two dogs.

The second dog is playing with a mechanism called the star picking pot, this mechanism is quite peculiar, it is a huge copper kettle, which is filled with all kinds of treasures, there is a steel claw hanging above the lid of the copper kettle, shake the rocker, you can control the movement of the steel claw, press the grab button, the claw will fall, grab all kinds of prizes in the copper kettle.

Xia Yu couldn't help but be happy when he saw it, isn't this just a crane machine? It seems that the prizes are different.

All kinds of charms, materials, spiritual weapons, magic weapons and the like.

Ergouzi's skills are quite good, he failed twice, and the third time, he successfully grabbed a prize, and soon the prize fell out of the spout.

It was a straw man, and I don't know what it was for, but looking at the rune paper sticking to the straw man's face, it should be some kind of disposable magic weapon.

The second dog picked it up and looked at it, his face was happy, and he immediately stuffed another spirit stone into it.

"Hey, you're lucky, Ergouzi."

"Luck? Hehe, this is not luck, this thing is skillful, when I mixed with the society, I didn't work for a while, I bought a doll machine and practiced for half a month, and I went to other people's doll machines to catch dolls and sell them for money, I'm too familiar with this thing, how about I have no interest in buying a few, ten spirit stones and a prize, all of which are good things. ”

It seems that the second dog has gained a lot, but Xia Yu still shook his head, most of the prizes caught in this kind of claw machine will not be too good, and this thing belongs to pure money burning, although you can get some loot, but the spirit stones will only get less and less, Xia Yu still wants to enter the top three, but will not waste spirit stones in this kind of game.
