I make dice...

I've decided to make a whole subsection of my website dedicated to various dice that I make. Most of these things are rather whimsical, and a person probably has to struggle to invent a real use for them. But some people, like myself, just like dice, and it's rather fun to have some that most other people don't have. If you see any that you like, most can be bought from me. I occasionally make custom dice for people too, but you should read this webapge before you send me any emails about custom requests.

Currently I am engraving 4-, 6-, and 20-sided dice. Initially all of my 6-sided dice were 5/8" (16mm), but I have also begun engraving 6-sided dice that are 1". Pretty much any of the 6-sided dice that you see below may be created at this "jumbo" size (though they are more expensive). These larger dice are only available in red, blue, and green colors. Here is a comparison of sizes -- using my Trigonometry Dice -- 5/8" vs. 1"... plus a quarter coin shown for scale.

I engrave new designs whenever I think of something (halfway) clever, so please bookmark the webpage and check back often. Oh, I also engrave geeky pencils.

4-Sided Dice

4-sided dice are always a bit awkward to roll and read results from. My preference for most d4 designs is to put the result at the upper point of the die rather than along the lower edge. See the Card Suits Die as an example.

Card Suits Die

Pretty straightforward, four suits, four sides. Inked with both red and black. Here you'll note the design style I like to use for 4-sided dice. The result (in this picture a Spade) is the icon which dominates the upper point of the tetrahedron. The alternate style is to put the result along the lower edge (closest to the table), but I find the former usually affords more room for artwork.

Compass Die

I do not recommend using this die to try to find your way out of the wilderness, but if you are leader of an adventuring party and just can't decide which door to take out of the perfectly rectangular cavern, this may be just the die for you.

Elemental Die

Another colorful 4-sided. This one is an "elemental die" showing icons for the four basic elements: Fire, Water, Earth, and Air. There are, traditionally, alchemic symbols for these elements, but they are all based on equilateral triangles and can be a little difficult to keep straight. I decided to just use some custom shapes for the elements and color them appropriately.

  • FIRE: Red flame icon
  • WATER: Blue water droplet
  • EARTH: Green octagon
  • AIR: White diamond (black outline)

    DNA/Nucleotides Die

    Here's a die I never would have thought about on my own, but someone requested them, so I made them. So, if anyone else wants 4-sided dice that depict the A, C, G, and T nucleotides of the DNA structure, you know where to find them.

    6-Sided Dice

    Unless otherwise noted, the 6-sided dice are 5/8" (16mm) cubes.

    1s and 2s

    Somebody wanted a "two-sided die" that was simply a six-sided with three 1s and three 2s. So I made him some. And, of course, I made extra.

    2 Pip

    This is probably the most unusual die that I've designed. Standard six-sided casino dice have their 21 pips (dots) arranged in particular ways. Imagine you have a "Bicycle" die that you've used so many times that the pips have started to wear off. What is the greatest number of dots that can be removed from a die and it still be determinable what is rolled?

    Turns out you can go all the way down to two pips. The spartan design is pictured at right. Here is how you can deduce what is rolled:

    • If the 'center-side' pip is face up, then a "6" was rolled, because that is the only number with a dot in that position.
    • If the center-side pip is not visible anywhere on the die, then it must be face-down. Meaning you rolled a "1".
    • Otherwise, the center-side is on one of the four side faces. In this case, look for the 'center-center' pip (which, given its position relative to the center-side pip, must be the "5" face). If that center-center dot is face-up, you've rolled a "5". If it is not visible, you've rolled a "2". If it is also on one of the side faces, then you need to know that the 4-5-6 values are placed counterclockwise about their shared vertex (on Bicycle Dice); with that knowledge you can determine whether a "3" or "4" is face up.
    The above makes a couple of assumptions. First, it assumes you know that this is a 2-pip die (with its particular pip arrangement), and second that you can move yourself to see all non-face-down sides of the dice once rolled.

    Also note that the center-center "5" pip could be moved to two of the corners and still work (but not the other two corners).

    Got all that?

    16 Pip Variations

    Here is a large set of sixteen dice that is another study on how pips (dots) may be placed upon a die. With the usual configuration of pips to represent the numbers 1-6 on a die's face, there are variations on how a particular arrangement of dots may be oriented. The dot configurations (the 2, 3, and 6) do not have 90 degree rotational symmetry; therefore, when they are rotated a quarter turn, the arrangement of pips looks different. Each of those three pip-numbers can be rotated a quarter turn or not, and this leads to eight possible designs if one were to look at the vertex (corner) of the die and see the 2-, 3-, and 6-faces.

    In other words, hold a typical 6-sided die so that you are looking right at the corner of it with the 2-, 3-, and 6-faces visible; now, each of those visible faces could be individually rotated 90-degrees, and your image of the die would look different (this is not true if you the faces are 1, 4, and 5 since they appear the same when rotated a quarter turn). Having three possible turn/no-turn choices gives you 23 == 8 possible variations.

    Furthermore, the arrangement of those three faces can be reversed in relation to one another. As you are looking at your die's corner, maybe the faces appear in 2, 3, 6 order reading clockwise around the vertex. This could be reversed so that they read 6, 3, 2 (or, 2, 3, 6 going counterclockwise).

    This doubles the number of variations (since any of the previous 8 can be reversed). So, there are sixteen possible variations total, and this set of dice includes one of each.

    All clear? If not, maybe the photograph to the right will help; each die is shown with it's 2-3-6 vertex prominent, and hopefully you can see how each is different.

    A set of these dice (in all red, green, blue, or brown) would normally be $32.00; I'll take a couple bucks off... say $30.00 for the whole set, if you are interested.

    Alignment Dice

    Another set of dice that harkens back to my childhood Dungeons & Dragons playing. A pair of dice that may be used to randomly determine the "alignment" of a character. The green die is labeled with LAWFUL, NEUTRAL, and GOOD, while the blue die reads GOOD, NEUTRAL, and EVIL. Rolling both gives equal chances for each of the nine possible alignment combinations.

    Archaic Number Words Dice

    Most people are familiar with the words "ace" and "deuce" from a deck of cards, but what many do not realize is that those terms were actually first applied to the number of pips on the face of dice. Furthermore, beyond "ace" and "deuce", the numbers 3, 4, 5, and 6 also have words associated with them: "trey" (which some still use in card-playing), and the rarer "cater", "cinque", and "sice".

    "Ace" was derived from the Latin word for "unit" while the other five terms are distortions of the French words of the same numbers. More information may be found at the Wikipedia page about dice.

    Anyway, I decided the archaic terms would look nice on dice...

    Binary Dice

    For anyone who loves the joke, "There are 10 types of people in the world, those who understand binary, and those who don't." This die has the numbers 1-6 represented as binary strings (1, 10, 11, 100, 101, 110).

    Book Genre Dice

    A customer was inspired by my Coffee Dice and asked me to create a die with different book genres on each face (the die is for a librarian she knows). The faces were adorned with the following words and icons: Adventure (globe), Mystery (question mark), Fantasy (sword), Science Fiction (alien head), Romance (heart), Biography (open book).

    Brick Dice

    I'm betting there's a fairly large overlap between LEGO-geeks and game-playing-geeks. For that audience I present these "brick dice". Instead of digits 1-6 on the faces, I have building block representations with one to six "studs" showing. The "5" side was tricky since there is not a standard 1x5 brick, so I depicted a 1x2 plate with a 3-stud L-brick next to it (the other digits are represented by a 1x1, 1x2, 1x3, 2x2, and 2x3 brick). These come in a set of 5 colored dice as shown.

    Note that these are in no way "official" products of the LEGO company (or any other construction toy company), these are products of me, Eric Harshbarger.

    Cheater-6 Dice

    This die might look like a standard six-sided with pips, but that is somewhat the point. Instead of a "1" on the face opposite the visible "6" in the picture, there's another "6". In other words, it's a die with two 6s (on opposite faces). I'm not responsible for players getting knifed or shot because they are using a "Cheater's Die" in some game of craps or Axis and Allies.

    Chess Dice

    Six different chess pieces, six sides on a die. This one was a no-brainer. I'm not sure how often people think to themselves, "gee, I wish this game of chess had more chance in it." But if someone does think that, I have the dice for them.

    After a specific request, I also engraved a couple of d8 with numbers (1-8) and letters (a-h) on them so that the buyer could, evidently, randomize the positions of the pieces on the board as well (using standard algebraic notation of the chessboard).

    Coffee Shop Dice

    This is a pair of dice I made for a local coffeeshop/bakery where I hang out way to often (often bringing puzzles for other patrons to play-test). Too often I'd hear the barista ask a customer, "what would you like?" and the response was, "ooohh... I don't know..."

    As a joke these dice are meant to answer their indecision. The white die has different drink types (Coffee, Tea, Chai, Latte, Bottled, and Frozen) while the yellow die has various dessert choices (Cake, Cookie, Cinnamon Roll, Muffin, Pie, and Cupcake).

    I don't know how often people follow the results of the rolls, but they do get a kick out of rolling them.

    Crown And Anchor Dice

    One fun consequence of making all of these dice is that I learn about dice games which had previously been unknown to me. Case in point: "Crown And Anchor", a betting game that is traditionally played by sailors in the British Royal Navy. There is a "betting board" or mat that is usually used in play as well, but I am just interested in the dice. They are six-sided, but instead of numbers there are three red faces (Heart, Diamond, Crown) and three black faces (Spade, Club, and Anchor).

    A game of Crown And Anchor requires a set of three dice to play, so that is what I have pictured here.

    d9 Pair

    One of my dice customers asked me if I had an opinion on the best way to create a "nine-sided" die. His suggestion was to number an eighteen-sided "dihedral" or "bi-conic" die with 1-9 twice. While that would work, getting such 18-faceted dice is not particularly easy.

    I settled upon the following scheme: a pair of six-sided dice. The first is numbered 1,2,3 twice and the second is numbered 0,3,6 twice. When the pair is rolled and the face-up values summed, the result will be 1-9 (with equal chances of each result).

    I have no idea why anyone would need a nine-sided die, but such a pair would do the trick. To the right are four such pair (in four different colors).

    Decision Dice

    These dice were originally designed for a friend of mine who requested a die to help her make decisions. I made two version, each with different responses, some negative so affirmative. Therefore, you can roll both (to get two differing opinions). For a more quantified answer I also included a number of plus or minus signs under the expressions (to indicate the relative severity of the response). So, you can roll both dice and see if the combined result is over all more positive or negative.

    Of course, I would not advise using these to dictate important decisions in your life; they are for entertainment purposes only.

    Emoticon Dice

    I have no idea how this could be useful, but I just liked the idea of covering the six square sides of a die with perfectly round emoticons. The interior of the die is made of white resin which did not contrast very well with the bright yellow surface after engraving, so I inked the etched faces by hand with a fine-point black Sharpie marker.

    Maybe if you are confused as to how you should react to some particular bit of news, you could roll this die and let Lady Luck decide for you. Here are the moods you might roll.

    Hash Marks

    There are all types of ways to indicate numbers, and "hash marks" is one of the oldest ways; I'm surprised it took me so long to think of using them on dice.

The picture to the right is also the first time that I'm showing off my latest available die color: brown!

    Buying These Dice


    I grew up playing tabletop role-playing games, including 1st edition AD&D (I still have all of my old modules and DRAGON magazines). I don't play anymore, but if I ever needed to roll up stats for a new character, I have created the ultimate geek-dice for just such a task: math-dice. Instead of dice with numbers one though six on them, I've designed three six-sided dice (blue, green, and red) with various mathematical expressions on them which equal the numbers 1-6.

    These are not your friendly, school-supply-store-dice to teach adding and subtracting. Screw that. If you want to know what number you've rolled, you better be fluent in calculus, matrix theory, probability, trigonometry, and modulo arithmetic. If you're lucky a die might land face up with "1+4" on it, or maybe just a square or cubic root. To the right is a picture of the dice, and here is a PDF file showing the expressions used on all of the faces. And yes, opposite faces add up to the fifth root of 16807.

    So, if your Dungeon Master can't calculate an infinite series or trigonometric functions, I guess he'll just have to take your word on how high that Agility Score really is.

    Here's a set of 20d6 I designed around the Period Table of Elements. I included elements from Hydrogen to Ununoctium. I tried to assign many similar elements to the same die (e.g. all the Noble Gases are on a single die), but I had to be somewhat lax as they don't break down into nice groups of six. I just randomly used red, blue, and green cubes for the dice colors in this picture.

    Each face (at 500 dpi engraving) lists the element Name, Atomic Number, Symbol, and Atomic Weight.

    Sicherman Dice (Pips)

    Sicherman Dice are a special pair of six-sided dice first discovered by George Sicherman of Buffalo, New York. The pair of dice have the numbers [1,2,2,3,3,4] and [1,3,4,5,6,8] on them, and while that is obviously different that the typical [1,2,3,4,5,6] numbering of a die, the pair, when rolled together have the same probability distribution for the sum as two normal dice rolled together.

    For example, if you roll two typical six-sided dice and add them together, you have a 1 in 36 chance of the sum being "2", a 2 in 36 chance the sum is "3", and so on; with the chance of summing to "7" being the greatest at 6 in 36.

    The Sicherman Dice match those chances exactly, and they are the only such pair using only positive integers that will match that distribution of the typical dice.

    I have gotten many requests for Sicherman Dice over the years, and I've finally gotten around to making some with pips (instead of numbers).

    Here's another design that is kind of begging to have someone make a clever board/party game around it: a "senses" die. Of course, there are traditionally only five senses of the human body (Sight, Hearing, Touch, Taste, and Smell), but that would have left one side blank. So, I included a brain for a sixth "ESP" sense. Each sense is represented by an appropriate icon (Eye, Ear, Hand, Mouth/Tongue, Nose, and Brain).

    Wonderland Dice

    I have brought back my "Alice In Wonderland" dice! These have proven very popular in the past. Previously they were made on jumbo (1") white, plastic dice, but when my supply of such blanks ran dry, I stopped making them. I got so many requests, that I decided to start making them using 1" wooden cubes.

    The wooden aesthetic suits theme very well (not surprising since the original artwork was produced as wood cuts back in the late 1800s). Wooden cubes, of course, are not quite as exact as urea/plastic dice; there will be variations in the wood's grain, and the corners and edges might be a bit scuffed. The darkness of the engraving may also vary a bit depending on a particular cube's density. I have done my best, however, to select cubes that are very close to "perfect" as far as size, and that will make beautiful dice.

    There are four different designs (24 different images total, six per die). The set of four Wonderland dice is $10.00.

    Most of the dice on this page I'm happy to sell if you think they are so cool you just have to own them. I make them "on-demand" as people request them and mail them by USPS. The cost for most of them depends on two factors: 1) the number of sides, 2) whether they are inked or not. Here are guidelines (but email me for a final total):

    (white lettering)
    (black inking)
    Colors usually available**
    4-sided N/A $3 Ivory
    6-sided $2 $3 Red, Blue, Green, White, Yellow, Ivory, Brown
    Jumbo (1")
    $5 N/A Red, Blue, Green
    20-sided, Jumbo N/A $10 White
    Shipping/Handling: add $5 per order for shipping within the United States. Shipping is free in the U.S. for orders totaling $50 or more. For shipping costs beyond the U.S., email me.
    * These colors are more because I ink the lighter colored dice (White, Yellow, Ivory) with black ink so that they are more readable (otherwise the white interior-material would not provide enough contrast). If you don't care about that, or plan to ink them yourself, you can save a little money.
    ** I do not engrave or make black dice.

    I might also be talked into designing wholly custom dice, but that would be much more expensive if I have to create new art files and so forth. If you are looking for custom dice, you should read my custom dice guidelines before you email me.

    If anything on this page interests you, email me with the specifics of what you would like (and please include a note about how you heard about my dice).
