**Magic Dice Game** (魔法のダイスゲーム) is a game played in Kakegurui Twin. It was the first game Mary Saotome, Tsuzura Hanatemari and Yukimi Togakushi presented in their new gambling den. It has proven to be successful and they earned quite some money. While playing it, the girls were dressed up as maids.

## Rules

   The game is quite simple. There are three dice used in the game. The guest picks one and afterwards the dealer choses one as well. Both players roll and whoever gets a higher number wins. The guest will receive double the amount bid. If he loses, the dealer will get the bettings. However the three dice have different numberings on them:

* The Black Dice has 3, 3, 4, 4, 8, 8
* The White Dice has 1, 1, 5, 5, 9, 9
* The Red Dice has 2, 2, 6, 6, 7, 7

### Cheat

Since the guest chose the dice first, the host had the advantage of choosing the best option against the guest's option, with a five out of nine chance for the host to win.

Black counters Red, Red counters White and White counters Black. That is because the probability of >> ex: Red vs White, Red has a 66,66% chance of winning, since two of the red dices number are higher than two of the white dices number. <<

## Game

### Prologue

After Mary discussed the game with Tsuzura and Yukimi, she opened up the business at the betting parlor. The first day went well and they won thirty million, but the next day it all went wrong as soon as Aoi Mibuomi started playing.

### Game

Two male students were the first to play. The first guy bet 1 million and chose the white dice. Mary took the red dice and won. So, in the next round, he took the red one and also won. Mary also told them that one student can only play three rounds a day.

She predicted that this is a kind of gamble where you feel certain of victory and it's very addicting. So naturally the players will bet higher but then they might lose and they make a profit. That is Mary's strategy. They earned 30 million yen during the first day.

The next day, Aoi arrived and asked to play before the next boy. He apologizes for taking his seat, but the other lets him take it. Yukimi recognizes him as Treasurer of the Student Council. Aoi sits down and Tsuzura welcomes him and then starts to explain the rules, but he says he understands, betting one hundred million for the first round after asking about the limits of betting amounts, much to Tsuzura and Yukimi's surprise.

Aoi just points out that changing the rules according to the player was unfair and the others agree. Yukimi notices how bad it would be if the salon's reputation wanes and even tries to refuse, but Tsuzura accepts before he can do that, saying that betting was risky. Both play and the victory goes to Tsuzura. Aoi congratulates her on that and, for the next round, bets two hundred million.

Meanwhile, Mary was heading back to the betting hall, wondering if it was being a success and, from the noise, assumed it was, walking in to find a startled Yukimi who informs her that they were winning three hundred million yen, much to Saotome's surprise. She watched as Aoi bet four hundred million yen for the final round. When he notices her through Tsuzura, he gets up and claims he was there to talk to her for having shocked Sachiko Juraku. He approached her and revealed that he knew of the trick they were using. When they revealed the results, Aoi won.

Explaining how it worked, he sat back down to continue the gamble and Mary noticed his strategy, blaming herself for not having thought of how to fight back.

## Results

Mary took the difference in money and gave it to him, but he refused; instead, he asked her to collaborate with his goals, claiming that he needed her to destroy the Student Council president, Kirari Momobami.
