March 187. Jeokma Dormitory Square.

“Lady. It’s a rule book.”

While Mina was dazed, Indira handed her a thin booklet of about 30 pages.

“This is your first time playing this game, so I will be there to give you some advice.

Oh, and here’s a card with my models’ abilities written on it.”

“Do you have one more copy? I want to see it too.”

“Of course, I also prepared a reference table for duel opponents.”

“Thank you. Here is a reference table of my models.”

Indira and Graven are already exchanging reference charts among themselves.

I was a bit embarrassed, but I couldn’t back out once everyone was cheering for me.

Okay, let’s do something! It hurts my pride that I am the only one who does not play the game distributed by Her Majesty the Crown Princess.

“Good! I’ll deal with you!

My brother has become the number one swordsman!

Just like my older sister became the magic number one!

I, Mina Karcic, will beat you in soldier play and become number one!”

Cheers erupted all at once from the Red Horse dormitory.

As if responding to the cheers, Graven also raised his right hand.

Goofy, who was sitting on my left shoulder, climbed up my arm, squeaking and waving.

“Good! Mina Karcic! The brawl has begun!

Hold the shield of model! Let’s pull out the sword called dice and face me!”

“Dice?”

“Here it is.”

Indira put the dice on a tray and brought them to Mina, as if she were serving a glass of wine.

“Thank you. …huh? Are these dice?”

Mina, who was checking the dice, stopped.

What was in her hand were not the six-sided dice commonly seen on gambling tables.

Ten-sided dice with ten faces colored in different colors.

It was in the form of two pentagonal pyramids superimposed on each other.

The first side seemed to have been specially polished, so it sparkled in iridescent colors and had the student council seal instead of a number.

The second side is yellow, with a font as straight as the sun, 2.

The third side is white with a 3 in a subtle half-moon-like font.

The fourth side is orange, with a 4 in a jagged font like a flame.

The fifth side is blue, with a 5 in a flowing font.

The sixth side is purple, with a 6 in a font that unfolds like the wind.

The seventh side is dark gray with a 7 in a font as strict as the earth.

The eighth side is green, with an 8 in a cute, grass-like font.

The ninth side is reddish-brown, with a 9 in a wild, animal-like font.

The tenth side is a black, nondescript 0.

Mina admired the dice as if fascinated.

The subtle full magical power felt from the dice gave an idea of the level of magic used in its production.

With this quality, I could make some money just by selling it as jewelry.

It looks like the student council really made up their minds.

“But why is it 10-sided and not 6-sided?

If we had used hexahedrons, there wouldn’t have been a need to make something like this…”

October 186. Student council room.

“Dodecahedron?”

Stop using your beak!

I leaned back.

But the vice president’s beak pursued me persistently.

No, even though it’s a fantasy world, isn’t it too much for the vice-student president to be a platypus beastman…

“Yes, we will use 10-sided dice.”

“The decahedron is not even a regular polyhedron!”

after. Just because something isn’t a regular polyhedron doesn’t mean it can’t be used as a dice.

I took out my notebook and pen and drew a 10-sided die with all sides having the same probability.

“This is a dice made by overlapping pentagonal pyramids with top and bottom symmetry.”

“I’ve never seen it before.”

“But it is possible.”

“Then who should make this?”

“Of course you have to make that, Tangaroa, right?”

Vice President Tangaroa glared at the president’s chair.

The Lilac Princess is sitting leaning on a soft chair.

She swiveled her chair around and said.

“You are in charge of production.”

“Chairman! I thought all I had to do was make a model prototype, but I didn’t know I had to make dice!”

“Making dice is simple. Just inject some full magic power into a piece of wood and voila.”

“Wow. Why would you say so rudely that it’s not your business?

And he doesn’t mean you have to make one or two dice!”

When Tangaroa glared at me, I shrugged and said.

“You should probably make at least 30 per person.”

“At least 30! Doesn’t that mean we have to take a few thousand pictures!”

The vice president was lying down on the floor.

he shouted, flapping his webbed feet and tail.

“No! No, I can’t!”

“Tangaroa…”

“Just buy a hexahedron at a gambling house and use it!”

The chairman smiled lowly, then looked at me and said.

“Tangaroa is like that, so is there a reason to use a 10-sided hexahedron?”

“Using a six-sided figure in a gambling hall is a disadvantage, not an advantage.”

There are almost no board games in this world, except for abstract strategy games like chess.

In such a situation, when people see ordinary dice and cards, they will immediately associate them with gambling.

“Students carry around cheap dice used in gambling halls.

How will parents view that? If possible, you should use different dice.

A dice with a sophisticated design that gives the impression of a luxury product.”

“Hmm. Then wouldn’t there be a way to not use dice at all?”

“That’s it! Chairman!”

Tangaroa jumped up.

“Dice should not be included in a duel simulator like this in the first place!

In reality, when I swing my fist, whether it hits or not is not determined by probability!

It depends on how the other person responds to me!”

“So this is what you’re talking about?

Instead of determining the success of a punching action by rolling a dice, let the player choose one of the detailed attack actions.

Should I hit him in the face or his arm? Should I throw a jab or a straight shot?

And the opponent has to choose a defensive action, and the hit and damage are fixed according to the interaction of those actions.

If you throw a straight shot and choose to block, it gets through, if you throw a jab and choose to dodge, the initiative continues to pass.”

In short, what Vice President Tungaroa proposed was the idea of making fighting games into tabletop formats.

The vice president responded to my summary by clapping his hands, or rather clapping his hands.

“Yes!”

“That is also a good system.

This could be implemented by using a system that simultaneously reveals cards with actions written on them.”

Tangaroa’s expression darkened when he realized that he would be making cards instead of dice.

Well, there are definitely board games that use that system.

but-

“If this was a game about one-on-one duels, it would have been done with that system.”

“Hmm. That’s not allowed. What I asked for is a game that embodies a fight between students.”

“What should not be done even if it is a brawl…”

“No way. If we had to fight like that for each attack, everyone would faint from exhaustion.

The president clearly requested a game featuring a brawl between 10 to 30 students that would be completed within 2 hours.

To make that happen, individual attack actions need to be handled simply.

They say we have to look at it statistically and probabilistically from afar.

All the variables and situations that occur during the actual battle are roughly crushed and expressed as dice.”

Professors, please open a lecture on probability and random variables at the academy.

Tangaroa was speechless, perhaps convinced by the explanation.

Rather, it was Lilac who presented a counterargument this time.

“But why is it 10-sided? Not an octahedron or a dodecahedron?”

“Because humans have 10 fingers.”

I opened my hand wide and showed my fingers.

“Chairman. When 100 10-sided dice are rolled, how many on average come up with a 7 or less?”

“70 units.”

“Which die comes up with a 7 or less when you roll it again?”

“49 items.”

“What if I do it one more time?”

“…34.3.”

“When 100 eight-sided dice are rolled, how many dice on average come up with a 5 or less?”

“62.5 units.”

“Which dice comes up with 5 or less again?”

“…I know what you mean. Since it uses base 10, the 10-sided hexedron is the simplest to calculate probability.

So what about the icosahedron? Even an icosahedron has a 5% chance of breaking.”

Ohh.

You are sharp, Crown Princess.

There are actually miniature games that use icosahedrons.

A TRPG derivative, or a 23rd century black ops game.

The advantage of the icosahedron system is that detailed expression is possible while maintaining the same probability of all dice values.

A 6-sided die has only 6 levels, but a 20-sided die has 20 levels.

If you want to increase the level to 6-sided, you can use the method of rolling several 6-sided dice such as 2d6 or 3d6 and adding them up…

If you have learned dice, you will know that because the variance is lowered, the volatility of the dice decreases.

The probability of getting 7 in 2d6 and 10 or 11 in 3d6 is higher than the probability of getting other numbers, so it is easy to predict the result.

The icosahedron does not have such a problem, so it maintains tension through high randomness.

At the same time, it is possible to realize a power fantasy that overcomes even such randomness.

That’s why TRPGs are the most used.

However, these are not suitable dice for use in our game.

“In any case, it is not as intuitive as the 10-sided hexahedron.

And…”

I held up the notebook and showed the design of a 10-sided die.

“There are 8 types of basic magical powers that exist in the world. The 10-sided hexahedron can assign one magic power to each face.”

“There are two left.”

“One is a wild card. One is a bust.”

Lilac nodded, satisfied.

“Are you satisfied with this, Vice President Tangaroa?”

“Then what I have to make is…”

“5,000 dice with a different color on each face and a different font for the numbers.

There’s no need to be too pressed for time. You only have to make it within 6 months.

Oh, I still have to play a test game, so can you make about 50 by tomorrow?”

“From now on, please don’t call me vice president, just call me a slave…”
