Deck100 is a deck of 105 playing cards that replaces the dice in your favorite paper RPG. Not only do these cards generate results more random that any but the very best of dice, but they also introduce a number of new rules that add excitement to any game session.

The first 100 cards are the “dice cards”, and also included are four Dragon Cards that may be treated like "jokers" for special effect. These are perfect for house rules you develop for this player-friendly product. The 105th card is an instruction card.

For use with any game system that uses fantasy polyhedral dice, Deck100 Original (the black box) has results columns for typical polyhedral dice d100, d20, d12, d10, d8, d4 and three d6-based results for 1d6, 3d6 and 5d6. Need 2d6? Just subtract the 1d6 result from 3d6 or draw two cards and add the 1d6 results. Each card includes four columns of random results, including the Heroic gold column with results skewed a bit higher. Perfect for that final, deadliest encounter! Each card also contains a special benefit, such as a bonus to a “roll”, that may be used by a player. 

Deck100 Indie Variant (the red box) has results columns for typical polyhedrals d100, d20, d12, d10, d8, d4 and two d6-based results for 1d6, and 2d6. This Indie Variant deck also includes dice results for uncommon die-types (d3, d5, d7, d14, d16, d24, and d30) used in games like Dungeon Crawl Classics, plus it includes Fudge dice for FATE Core.

How to Use Deck100

Here's an extremely elaborate example that encompasses lot of different situations. Once you're used to the cards, getting a dice result is usually as simple as flipping over the next card and reading a result!

1. Shuffle 100+ cards. Use at least the 100 "dice" cards but add as many additional "dragon" cards as you like. These extra cards could be Deck100 branded (i.e. they have the Deck100 logo on the back of the card) or they could be the "art cards" that have the image of the dragon on both sides.

2. Place the cards face down and flip over the top card. This card is NOT read for a dice result, but is a "starter" card. You read only the color of the dragon at the top of the card. If you have a difficult time determining the identity of the dragon at the (due to color blindness or other reason), then refer to that aforementioned instruction card. The dragons are stacked and numbered 1 thru 4 on the left side of the card. This order corresponds with the order of the color columns across the dice results cards, i.e. black, red, blue, gold. So if the "starter" card has the black dragon (#1 on the instruction card), then that's all the information you need to get from this card.

3. Play your game.

4. The first time a die roll is called for, say when your character in an RPG is using the sleight of hand skill to expertly shuffle a deck of cards and you need a d20 skill roll result, you turn over a second Deck100card. Since the "starter" card indicated "black", on the second card you look down the "black" (or far left) column and ignore for now the color of the dragon on the top of this card.

Because the "Starter" card was a black dragon, read down the black column for a d20 result. In this case, your result is the "dragon" icon.

Because the "Starter" card was a black dragon, read down the black column for a d20 result. In this case, your result is the "dragon" icon.

5. This card does not provide a numerical result in the black column and d20 row. Instead, there is a "dragon icon". You can make whatever homebrew rule you wish for this, but the default purpose of the dragon icons here allows the player who needed the die result to either refill her hand of 2-3 cards for the purpose of using the "Special Text" at the bottom of the card or if she already has a full hand of cards, she may draw a card to replace one of the cards already in hand. We'll assume the player already has a full hand, so she draws a third card for the facedown Deck100 stack, decides she likes the special text, puts the card in her hand and then selects a card in her hand to discard. The color of the dragon on this card will determine the column for the next dice reading, so she can only blame herself now (or she could discard a gold dragon-topped card and give herself a reading on the heroic column — perhaps overkill for rolling sleight of hand, but we'll say that's what she does!)

The player discards this card to keep the new card in her hand for "Special Text" she prefers to only getting an extra 1d4 on a dice result.

6. Now the player still needs a d20 result, so she turns over a 4th card. Since the top discard card has a gold dragon at the top, the player reads down the gold column and across the d20 row to get a dice result of "12". The sleight of hand skill check roll on a d20 is "12". Note that while this is the result in the gold column, it's not the best d20 result on the card. This will often be the case.

The gold result may not be the best on every card for every die type, but as a whole the gold column results skew higher than the actual probability that is reflected in the other three columns.


7. That "die roll" is resolved. Now you may need to roll for an NPC to notice that this player stacked the deck as she shuffled the cards. If that's also a d20 roll, then you'll flip over a 5th card and read down the black column and across the d20 row. That's because the top card on the discard pile once again has a black dragon at the top (see card above, the one that gave the d20 gold column result of 12).

8. Re-shuffle whenever you wish. Frequent reshuffles will generate results that best reflect true probabilities.

Using the Dragon Cards

You just need to determine what it means to draw a dragon card like this:


A quick and useful purpose of these dragon cards allows the player who draws the card to choose the color of the column he reads on the card he flips AFTER the dragon card. So, if the top card in the discard pile says he should read the blue column, and then he draws this red dragon, the player then then flips the next card and may CHOOSE between the results on the blue and red columns.

And since there are dragon cards with a Deck100 back and ones that have dragons on both side, you can ascribe two different purposes to the dragon cards! The art cards make nice "wild cards". Allow the player who draws it to add the card to his hand. Then on any future card, instead of reading the column he's supposed to in order to get a dice result, he can discard the dragon art card and instead get the result in the column of the appropriate color. A very powerful special effect!

I hope all the above helps!

Deck100 Original and Deck100 Indie Variant are both available in PDF and POD on DTRPG. Both versions of the dragon cards are also available as separate 4-card PDF and POD. The price for the decks is a couple bucks higher at $17.99 but this is because POD is more expensive per deck.
