Tokyo: Rabbit Police and Her Evil Partner

Chapter 319 Three Doors Problem
Damn, how come this guy is so accurate?
For the first time, Fushimi Shika cursed in his heart. He didn't care about losing 10,000 yen. He just wanted to know how Satake Gen won.

Besides, the look on Satake Gen's face after his victory really deserved a beating.

"Stop playing!"

Fushimi Shika threw the cards down, stood up and left. Although his will attribute was only C, his IQ was still S, and he knew to cut his losses in time.

Ishii Takamasa wanted to persuade him again, intending to provoke him with a few words to make Fushimi Shika go crazy. Once he lost all his money, he would naturally work obediently for the Inagawa Society.

However, Satake Gen stopped the president with his eyes, indicating that Fushimi Shika could leave. If he wanted to play the joker card game again in the future, he could always come to him for a round - he was worried that if he continued to gamble, Fushimi Shika would get angry.

Just as he expected, the gambler Fushimi-kun was in a bad mood and took a bottle of red wine with him when he left.

On the way home, Fushimi Shika was still wondering how he lost.
He heard that some cheaters would use specially made playing cards, with patterns on the back of the cards that contain a secret, and the brand number could be identified through the subtle patterns...

Could it be that Gen Satake bribed the restaurant waiter in advance, so that even the playing cards he bought at the front desk were specially processed?

No, he believed in his own eyesight. He had checked the cards himself and there was no special mark on the back of the cards.

Catching joker cards is not like playing Texas Hold'em. It does not require any advanced skills like card memorization. Both sides basically play with their cards open - the only point of the game is the few seconds of drawing the cards.

How did Gen Satake do it?

Fushimi Shika felt a little regretful. He should have taken the two decks of cards with him and studied them carefully after returning home. If he returned to the restaurant to ask for the cards now, he would appear to be stingy.

Although he is indeed stingy, he doesn't want others to think he is stingy.

After returning to the Sugamo apartment, Fushimi Shika took out the key to open the door. The door of the next room suddenly creaked open, and Shirakawa Miki showed half of her face. She grinned at him foolishly and muttered something about seeing you in the new world... He was already in a bad mood, and after seeing this scene, his mood became even worse.

"Cerebral palsy stuff."

Fushimi Shika didn't tolerate her. He spoke clearly in front of her, and after scolding her, he opened the door and went back to his room.

Gen Yuzi hadn't finished her gun practice yet, and the living room was empty. Fushimi Shika was curled up on the sofa watching TV, but couldn't concentrate at all. The more he thought about it, the angrier he got, so he simply asked Ping Yingzi to play the joker card game with him.

Although the latter is precocious, he is still just a seven-year-old child after all. He will not refuse to play games with acquaintances, even if the guy is a cheating guy like Fushimi Shika.

In order to find out how Satake Gen did it, Fushimi Shika imitated Satake Gen's actions and words, pointing to his own card and claiming that it was "JOKER" or some other number card.

The two played more than sixty games in a row, with each winning and losing.

Fushimi Shika calculated that Hira Sakurako won 36 games, while he only won 24 games, which means that Hira Sakurako's winning rate was 10% higher than his.

Moreover, during the game, Fushimi Shika discovered a pattern:
Whenever he has three or more cards in his hand, he declares that a certain card is a "joker", and Ping Yingzi will change her choice without hesitation and draw another card; when he has only two cards in his hand, he declares that a certain card is a "joker", and Ping Yingzi will draw the card he declared without hesitation.

Afterwards, he asked Ping Yingzi why she did this, and the latter gave a mathematical model based on three problems:

"In summary, the probability of winning by changing cards is (\frac{2}{3}), and the probability of winning by not changing cards is (\frac{1}{3}). The mathematical model proves that changing cards is a better strategy..."

Fushimi Shika understood what it meant. The general meaning was: when he declared that a certain card was a joker, the probability of winning by changing the card was higher.

But it only increases the probability of winning by about 10%, and it cannot make the victory as certain as Satake Gen.

Before the cards were opened, Satake Gen had already declared his victory, which means that Satake Gen knew in advance what cards he had drawn... This guy definitely cheated, but he just couldn't see his tricks for the time being.

After Gen Tamako returned home, Fushimi Shika asked her to play joker cards again. It happened that Ping Yingzi was tired of playing, so Gen Tamako took over.

Gen Yuko was not interested at first, thinking that playing Joker cards with two people was meaningless. Until Fushimi Shika proposed gambling on indulgences, she immediately became interested - indulgences were not considered currency, so they were not gambling. In order to make a fortune and save up the red indulgences as soon as possible, Gen Yuko hurriedly took a shower, without drying her hair, and the ends of her hair were still wet. She hurriedly knelt on the sofa and urged Fushimi-kun to open the cards quickly.

Fushimi Shika planned to beat the weak player severely to make up for the loss of 12,650 yen. He cheated in anger and dealt the joker card to Minamoto Tamako when shuffling the cards.

The latter did not notice it. He held the five cards in his hands and looked at them carefully in front of his eyes.

"I'm going to draw a card..."

Fushimi Kaka stretched out his right hand and placed two fingers on the first card on the left. Gen Tamaki couldn't help but smile with delight. So Fushimi Kaka moved his hand away and placed it on the second card. Gen Tamaki's face immediately fell and she looked nervous.

"..."

It’s really easy to understand.

Fushimi Shika reached out and took the second card. Gen Tamako pouted, looking unhappy.

He turned it over and saw that it was indeed a pair of cards.

Within three rounds, Fushimi Shika collected a pair, played all the cards in his hand, and won easily, winning a white indulgence from Yuan Yuzi.

"Are you cheating?" Gen Tamako expressed his doubt. After all, Fushimi Shika won too quickly.

She asked for a change of cards and asked that she be the one to shuffle and deal the cards.

Fushimi Shika didn't care. With Yuan Yuzi's personality, she would definitely not cheat, and it would be easier to let her shuffle and deal the cards.

The second hand officially began. Yuan Yuzi was lucky. She had no joker cards in her hand, and it was her turn to draw first.

Just as she was about to reach out to draw a card, Fushimi Shika raised his right hand in a mean manner, pointed at a card in his hand, and said maliciously: "This is a joker card."

"Eh?" Yuan Yuzi was stunned: "What does this mean?"

Fushimi Shika did not respond, still keeping his right index finger hovering over the card in his left hand.

Gen Yuzi's eyebrows stood up together, and her little brain began to think rapidly, wondering if this was a trap - Fushimi-kun might be telling the truth, deliberately going against logic, or he might be lying, trying to trick her into drawing a card, or he might be going against logic's counter-logic...

Humph, she won’t be fooled!

Yuan Yuzi was very stubborn and determined in her choice. She reached out and took the card, then turned it over and her face fell again.

It was "JOKER".

What happened? Fushimi-kun didn't lie...

Yuan Yuzi was extremely disappointed, staring at the six cards in her hand, calculating carefully which pair to play. After she played her cards, Fushimi Shika became playful, subconsciously pointed at one of her cards, and deliberately said with a smile: "This is 3..."

As soon as he finished speaking, he realized something.

hiss……

like……

Am I being fooled too?
