Gameplay
Games of Demon Dice/Chaos Progenitus are generally brief (about 5-15 minutes). Each die has only three unique sides, apart from a handful of misprints where portions of two dice were combined. A die's identifying face will have a special ability depending on the body part or item type represented; the other faces will bear damage sources, "blocks" which prevent damage, "Plus" icons that make damage harder to block, and "minus" icons which prevent dice from being rolled for a turn. Damage inflicted is either "stun" or "wound", with "stuns" healing over time and "wounds" usually being permanent.
A demon always consists of exactly thirteen dice; of these, at least one must be a "body part", rather than an item; a fiend is defeated when it no longer has a body part die which can be rolled on its turn, either due to damage or "minus" effects. Items usually have more powerful abilities, but do not keep the fiend "alive".
If all of a demon's dice are of identical plastic and ink ("flesh and blood") colors, it is considered a "pure breed" and gains a special ability tied to its concept (for instance a combination of blue and yellow indicates a "frost fiend" which slows the enemy demon's healing process). A fiend also gains special abilities if it consists of at least half dice of one color combination (a "half-breed"), or if no two of its dice are exactly the same (a "mongrel"). Eight unique combinations (red, blue, black and yellow dice with ink in the same colors) of dice types were produced, three of which were confined to Chaos Progenitus's first and only expansion.
