SO FUCKING UGLY. But he has a fetching hat.

Dice (singular: die) are high-impact polyhedra. In role-playing games and tabletop war games, they are used as randomizers to inject an element of chance into the game. Non-gamers often only know about the six-sided die (hereafter referred to as the d6) thanks to the ubiquity of games like Monopoly and Yahtzee. Which dice are used tends to vary by system. Dungeons and Dragons, for instance, makes use of all types. On the other hand, White Wolf games and Classic Traveller use only ten- and six-sided dice, respectively. On the gripping hand, some games don't use dice at all! These tend to be relatively new games like Nobilis or Amber.

If you do not have dice for whatever reason, consider chits.

Dice are considered by most people to be impartial arbiters of random chance. Fa/tg/uys know better. Dice are controlled or at least influenced by the unseen force of Dice Mojo. It is believed that Dice Mojo can be influenced by players through manifold rituals, including:

  • Placing a die with the desired number upward, that it 'gets used to' that position and tends to return to it.
  • Placing a die with the desired number downward, that the die is tricked into thinking it has already made a bad roll and will produce a good outcome on the subsequent roll.
  • Rolling a die until a string of good rolls are achieved, tapping into a streak of 'good mojo' or 'rolling out' bad outcomes.
  • Various chants, prayers, threats, and curses made toward the die in order to entice or coerce it into producing favorable rolls.
  • Being careful not to drop dice or just roll them to pass the time till next turn, as when rolling a twenty, the critical ratio may be "used up" for the day.
  • Building dice towers as tribute to Dice Gods that they may bless one's dice with good Mojo.

Dice on /tg/[edit]

/tg/ has a dice-rolling function. Simply type dice+XdY+Z, dice+XdY+-Z (for subtraction) or dice XdY Z (the Z is optional) into the email field to roll X dice with Y sides and add a modifier Z. You can also type noko dice+XdY+Z, noko dice+XdY+-Z or noko dice XdY Z to use the site's noko feature. However, your input is not visible this way, which can lead to accusations of cheating.

Types of Dice[edit]


A D2. Careful not to spend it all in one place.

A d2 isn't a die - it's a coin.

You flip the fucking thing. Heads count as 1, Tails count as 2.

You can, alternately, roll any other die - counting odds as 1 and evens as 2.

In Various Works[edit]

d2s are used with disturbing frequency in both CCGs and RPGs. They are used in Magic: The Gathering, and even Dungeons and Dragons because some faggot developer thinks it's fucking funny to have certain items and weapons do damage using d2s even to this fucking day.

The RPG Bean! is a d2-based game, and it's actually pretty good.

Also Currency[edit]

The d2 are the only dice you can put in a vending machine and spend for candy.


Not much to say about it.

The D3...

Warhammer 40k uses D3's every once in awhile - Rending, Manticores, & other cases such as +D3 attacks, 2 + D3 objectives, etc. Most of the time, they don't actually use a D3 - they just roll a d6, at which points two schools of thought engage in a holy war:

  • Some substract 3 from any result that's 4 or higher. So, for example, a 5 becomes a 2.
  • Others divide the result by two, rounding up. So, for example, a 5 becomes a 3.

The 40k rulebook explicitly proselytizes the latter, which means the former is heresy.

Actual d3s come in two major flavours: The weird triangular nublette things seen to the right, which are largely used by people who think having weird dice makes you interesting, and d6es which had 1, 2 and 3 written on them twice, used by people who like to build things out of dice.

Since you can readily simulate a d3 result easily enough without obtaining extra dice why in the hell would you bother?


This fucker will hurt.

A pyramidal die that has the second-sharpest points of any die (only the d8 is sharper), and, appropriately enough, has four sides. Used by Wizards, small weapons, and low-caliber firearms in d20 modern. At least it gets more love than the d12, which probably falls asleep every night in a pool of tears and melted butter.

There are two ways to print the numbers on a D4. On one, the numbers are arranged on the corners of each face, and so the number at the top (it will always be three of the same number) is what you actually rolled. On the other kind, the numbers are arranged in the middle of each side of the face, and so the number on the bottom (again, it will always be three of the same number) tells you what you rolled. Oldfags will insist the "numbers on the bottom" d4 is the one true way, despite the fact that they need the full power of their coke-bottle glasses to see the numbers. Don't argue with 'em, just keep using the d4s that you and everyone at the table can read.

Fucking Caltrops[edit]

Whilst the d4 isn't as sharp as a d8, it has one major bit of natural defense - no matter what way it lands, it will have a point face-up. Because it's the smallest die, care needs to be used - if one escapes its dice-box and into the wild, it will wait, with its natural weapon ready, for the exact moment someone walks into its vicinity barefoot to strike, whereupon it will inflict some surprisingly-vicious puncture wounds.

Somewhat related, in D&D Caltrops inflict 1d4 damage. Coincidence?


Not the same thing as the D6 System by West End Games.

do-it-yourself kit

If you don't know what a d6 is, holy shit are you in the wrong place. Go back to playing monopoly in your blissful ignorance that uses two of them.

Fun Fact: Do you own a regular #2 pencil? If so, congratulations, you have a d6.


A die-rolling method for numbers from 0-5 with a particular curve.

Roll two d6, and subtract the smaller from the larger.

The curve looks like this:

roll odds %  
0 1/6 16.7% ######
1 5/18 27.8% ##########
2 2/9 22.2% ########
3 1/6 16.7% ######
4 1/9 11.1% ####
5 1/18 5.5% ##


The eight-sided die is an octohedron: one of the symmetrical polyhedra known as the "Platonic solids."

Buncha d8s.jpg

It looks like two pyramids having lezbo ass-to-ass sex.

A d8 was always used for hit points for Dungeons & Dragons monsters, and in Advanced D&D it was used for those classes that have more hit points but weren't supposed to be as butch as Fighters or Paladins.

Eight-sided dice also have the most variations with weird not-numbers stuff on them, like compass directions, random weather, letters. They're also used as below-bargain-basement minifigs because one point is always off the table, like a big nose, or turret.

When you played Dragon Dice, the d8s were the terrain, which could change under your feet without moving your army, somehow.

James Ernest came up with a game "Dogfight" that uses d8s for their numbers, for being pointy and for turning in circles when you try to roll them like wheels... then he remembered that people put weird shit on d8s and he came up with a new game called "DiceLand." He even tried adapting Steve Jackson's Ogre to his d8 faggot-tree, but it didn't become popular enough to generate any grognard rage.


Ten-sided die.png

It's a die. With ten sides. Pretty simple concept.

It's in the shape of a pentagonal trapezohedron. You can stand it on its point and spin it like a top.

Your d10 dice are not this good-looking.

Rolling d100 Using Two d10s[edit]

Some Systems require you to roll d100s frequently. There's a better way of doing it than rolling a golf ball with 100 sides.

Get out two d10s. Use one die to denote the singles digit and another die to denote the tens digit. Some d10s have two digits per side (see above) to make differentiating your digits easier, but you can roll d100 with any two d10, provided you specify beforehand which die is the tens and which the ones.

Reading it off is simple. Did you roll a 20 and a 4? That's a 24. A 90 and a 1? 91. A 00 and a 5? Just a 5.

The only possibly ambiguous result is two zeroes: a 00 and a 0. Obviously you rolled a 100. Why? Because the alternative is a 0 which you can never roll with any other die. That, and the system assumes a roll from 1 to 100, not 0 to 99.

Mathematically, each digit is determined in an independent manner. There are exactly 10*10=100 two-digit combinations, all equally likely. You now have a uniform distribution of 100 different results, as desired.


D12 Cries.jpg

The d12 is the loneliest die. It is used for barbarian hit dice and greataxe damage in Dungeons & Dragons. The fact that Orcs (and Half-Orcs) are both the most common barbarians and the most common wielders of greatatxes, it is suspected that Gruumsh is the head of a conspiracy aiming to eliminate the d10 in favor of the d12, in order to "purify" dice sets so that they consist only of true platonic solids.

Observant smar/tg/uys will notice that d12 are the hitdice used for undead and dragons instead of the usual d8s.

d12 is the highest stats can ordinarily go in Savage Worlds or Ironclaw. BBEGs and DMPC Mary Sues can have d20, but it's hella rare.

d12 shows up in Cthulhu-themed games, like Pokethulhu or Cthulhu Dice, probably because d12 is the mutant freak of dice. It's also used quite a bit in Ironclaw, because furries like to imagine that they're abused or neglected so they take neglected dice.

One of the few places where the d12 is not lonely, and is in fact used a great deal, is the DragonMech campaign setting. Its chief use there is for damage rolls with mech weaponry.


Before TSR/Wizards of the Coast tried to trademark "d20", every gamer knew what the fuck an icosahedron is, and why "natural 20" is a gift from God.

We're Number One
The d20 System for role playing came later.

Like eighteen centuries later.
Don't believe me? Check this out:

2nd century Rome, bitches


D30 olympic.jpg

Only ever used for those critical-hit tables when you rolled a natural 20. Or if your DM was rolling damage and felt like being a dick.

But man, would it leave a bruise when your little sister threw it at your head.


Fifty goddamn sides!!!!

For when you want to do 2-100 points of damage with a vaguely normal distribution.

... yeah, I don't know either

It also doubles as a golf ball.

D50 Alan Davies.jpg



Take that, D50's.

They're useful when you really want to take 5 minutes to find out if you hit something in Dark Heresy. In other words, better just use a pair of D10's like a normal human being.

Apparently it took about 6 years to make this die. I guess this means that it takes 6 years to put the numbers 1-100 on a fucking golf ball.


It may seem awesome when you see it, but as soon as you get one (and whoever's selling it to you is also aware of how unspeakably lame it is, and will probably even tell you) you will find that it has two major flaws: it takes about a minute to stop fucking rolling around and if you aren't blessed with a perfectly level playing surface you will never find out exactly what you've rolled (and when there are six other numbers right next to the 100 and 1, that's a pretty big problem). Oh, and to top it off, it isn't even very balanced, so it's effectively a loaded die.

On the other hand, if you hate your friends, show up to your next meeting and sweep all the d10s off the table, then drop your d100 right in the middle with a theatrical gesture and watch as everyone is mesmerized by its incessant rolling (see: takes about a minute to stop fucking rolling around). Take this opportunity to pocket the d10s, run away and never come back.

FATAL seemed to expect you to use this (but then again FATAL expects you to play FATAL so you can't expect much).
