New Numbers

UNO Hell introduces a wide variety of number cards with differing values, and this page will serve as a list of every single **new** number addition to UNO Hell, not including the base UNO integers from 0-9. With that extra bit of clarification out of the way, the entire list of new numbers, from smallest, to largest.

***The random vertical lines should not be removed, they're the things keeping the images and the text aligned!***

## Negative numbers

There's only three numbers in this category, two of which are integers.

### Negative 10

The smallest number in UNO Hell, taken from the game ONO 99, which also happens to have one of the largest numbers down the list.

### Negative 1

Negative 1 is the largest negative integer, and the second largest negative number only behind Negative 1/2. (see below)

### Negative 1/2

The largest negative number in UNO Hell. and the only non-integer negative. I definitely completely made this one up.

## Positive numbers (Pre-10)

This category includes every positive number less than and including 10, not just integers. There's going to be a lot of irrational numbers in this section, so, get ready for those.

### 1/2

The smallest positive rational number (that isn't 0) is 1/2.

### Square Root of 2

The first irrational number on the list, Square Root of 2 as an irrational number does have a few different properties over regular numbers. All irrational numbers are made to be in between 2 integers, (in this case, 1 and 2,) and some of the starting digits are displayed on the card at low-opacity black, which is an interesting art decision.

### The Golden Ratio

The second irrational number on the list, that also happens to go between 1 and 2. The only different between Square Root of 2 (see above) and The Golden Ratio is that 1/2 (see above) can be played on Square Root of 2, but **it cannot be played** on The Golden Ratio, as the distance on the number line between 1/2 and The Golden Ratio is greater than 1.

#### Fun Fact

The Golden Ratio is the only irrational number to not have custom art, and instead be a symbol copy-pasted into Scratch's built-in text feature with nothing else added to it. (Example: Square Root of 2. The 2 part is in fact Scratch's built-in text, but the square root symbol isn't.)

### e (Euler's Constant)

e, (Otherwise known as Euler's constant) is an irrational number approximately equal to 2.71, and is the irrational number meant to go between 2 and 3.

### Pi

Approximately equal to 3.14 and the most popular irrational number on this list is Pi. It goes between 3 and 4, and doesn't have many more interesting properties, it's just there.

### Derf

The first fictional integer on the list, this one being the supposed integer between 5 and 6, yet can't be played on either one.

### Thrembo

Another fictional integer included in UNO Hell (and a really popular one in general too) is Thrembo, the supposed integer between 6 and 7, and, again, cannot be played on either.

### Tau

Some may argue that Tau should go before Thrembo, but, the order of the numbers doesn't really matter that much anyway as long as they all at least vaguely follow a generic pattern. Tau is what some people argue to be the "real" circle constant instead of Pi, and has numeric value of Pi doubled.

### Solve For b

One of the three variants of the "solve for variable" symbol. This time, the formula for the numeric value is (2\*The Golden Ratio) factorial. This is approximately equal to 8.13, and if therefore the irrational number between 8 and 9.

### 10

The only **real** integer in the Pre-10 section is 10 itself. Not a base UNO number, but instead, taken from DOS.

## Positive Finite Numbers (Post-10)

Every positive finite number greater than 10 resides within this section. And yes, the term "finite" is necessary.

### 11

The first integer in this section, and definitely not the last one.

### 12

I swear this list gets more interesting than just counting up.

### 35

This card actually has some noteworthy things to mention about it. Firstly, the card is mostly gray, with the color of the card represented by the color of the glowing 35 in the center, an art choice which was inspired by this video.

### 50

Made because the 50/50 symbol also had numerical value 50, and that was to be made clear by this card, as they can be played on each other.

### Wild 69

A joke card, with the hidden "original intent" for this card never having been implemented, it now resides with the rest of the number cards with having no interesting properties.

### ONO 99

The only number with special properties. The ONO 99 card has no color, and cannot be matched with any number (because no number gets close enough to do so), so the only cards that can be played on the ONO 99 (that aren't other ONO 99 cards) are cards with the Wild symbol.

### 100

A joke number added purely for the fun of it. This card is what you draw if you play the Wild Draw 100 symbol, which is the point of the joke.

## Infinite numbers

Do you see why the term "finite" was necessary? These cards can all be played on each other, as they are all infinite.

### Generic "Infinity"

There isn't really an order for these, so, Generic "Infinity" is going to be the start of this category, with no special properties aside from being infinite.

### Aleph 0

Otherwise known as "The Cardinality of all Natural Numbers", or "Countable Infinity", Aleph 0 is the "smallest" infinity, but, there's so few infinite numbers that it doesn't really matter.

### Ω (Omega)

Otherwise known as "Absolute Infinity", or "The Largest Infinity To Ever Infinity", Omega is going to wrap up this category.

## Complex/Imaginary Numbers

Imaginary numbers do make an appearance in UNO Hell. There's only a few of them, but they do in fact exist.

### i

The base imaginary unit. i is the square root of negative 1.

### Solve for c

Yep, that's where the third variant for the "solve for variable" symbol went. It's a complex, or, imaginary number. It's just the square root of negative one, and therefore can be played on i and vice versa.
