INTERMIXX is an RPG Mash-Up — a remix of cool ideas and styles to create a fun gaming experience all its own. This is a barebones, blank canvas DIY rules set.

I assume if you’re reading this you’re already familiar with role-playing games and how they work. I also assume if you find any rules lacking, you know how to steal ideas from other systems or fill in the blanks yourself. So go grab yourself two six-sided dice, something to write on, and some friends. Think up a setting or genre you want to play. Brainstorm, improvise, and most of all: have fun.

Version 1.2 –

  • Replaced Advantage & Disadvantage” with Snap Rolls”
  • Added suggested Progress Track sizes

Version 1.01 –

  • Light Edits & Clarifications

Game Play

Players take on the role of individual characters.

The Guide plays the world” that the characters exist in.

For every interaction the player characters have with the setting and its inhabitants, the Guide facilitates the results.

Core Resolution Mechanic

Players do all of the dice rolling. The Guide interprets the outcome.

Dice are only rolled when the risk of failure is substantial and interesting. Easy tasks, or endeavors where failure will only stall the pacing, should just be given success.

To make an action roll, the players roll and add 2D6(+/- Modifiers) and compare the results below:

  • (8+) Success: The character overcomes the challenge and achieves what they set out to do. Rolling doubles” (or matching dice) provides an additional benefit to their success.
  • (7 or Lower) Setback: The character suffers a lesser consequence or partial success. If there is risk of harm, they are wounded or take an injury.
  • (Double Setback) Disaster: If matching dice are rolled on a Setback, the character suffers the full risk of their actions. If there is a risk of harm, a major injury or even death is on the line.


  • Most action rolls are eligible for a bonus if the character has a related Skill. Each skill is rated +1 to +3.

  • For more challenging tasks and situations, the Guide may impose a Difficulty modifier ranging from -1 to -3.

  • Generally speaking, lacking a skill is simply a +0 modifier to a roll. However, if the task feels particularly out of the character’s purview (specifically if none of their Traits qualify any experience with the action) then the Guide may impose a Difficulty.

Snap Rolls

If a character has a special Trait, item or circumstance that would merit a significant edge or advantage in a situation, they are afforded a Snap Roll. A Snap Roll” means to re-roll on an action whenever a Setback occurs (hence, it is to snap back” from failure or harm). There is a catch — the player must accept the new roll, for better or worse.

Conflict & Hindrances

  • All conflict is handled at the pace of narration. Any actions a character takes to engage, overcome or bypass the opposition is handled like any action roll.

  • Rolling a Setback during a conflict may inflict the character with a Hindrance. A hindrance is a negative trait portraying a condition (like stressed, wounded, frightened, exhausted, embarrassed, blinded etc.) or an injury (broken arm, gouged eye etc.).

  • The Guide may apply a penalty (rated -1 to -3) based on the severity of the Hindrance on actions deemed complicated or obstructed by it.

  • Specific to physical altercations, a player may choose to break an item or belonging (armor, weapons, gear on their person etc.) in order to prevent or reduce harm.

  • Minor hindrances can be recovered in scenes of downtime following the conflict. Those inflicted from physical harm may require medical or technical treatment. Major hindrances and grievous injuries will have to be recovered over longer periods of time.

Progress Trackers

For more complicated tasks, obstacles or encounters that would require several actions or prolonged effort to overcome, the Guide may wish to use Progress Trackers. This can take many forms — they could draw a number of boxes to be checked off, sketch clocks” with varying pie-slices to scribble out, denote a pool of points or tokens to reduce, or even using spare dice to count progress towards the goal.

  • Name or declare the obstacle the tracker represents, like horde of zombies” or corporate firewall”.

  • Every successful action taken towards overcoming the objective gets the players one step towards their goal. A double” success or, optionally, rolling a total over 12+ may progress them an additional step.

  • Setbacks are open for interpretation — for instance, the Guide may decide for an Evade the Cops” endeavor. Every Setback reduces the players’ progress by 1 (and rolling a Disaster will result in them being caught). Meanwhile, a Ninja Ambush” could see every Setback as a partial success with consequence, and Disasters leading to severe injuries.

Progress trackers can be used for short term and long term endeavors, and not necessarily against opposition or with high-risk. Character goals (like learning a spell, building a robot, persuading the public etc.) can be tracked over time this way.


  • 4-6 for tasks that take up an important scene or encounter during play.
  • 8-10+ for more drawn out events, battles, or to track progress over a session.

Character Creation


Traits are special descriptors that establish facts about your character and help lay the foundations of their experience in the setting. Each trait is written down as a brief statement or small sentence. For your character’s starting traits, answer the following questions:

  • What is their Concept?
    What is it that the character does? This can be their profession, an archetype in the story, a background or what have you. It’s recommended to include an Adjective and a Noun; any special ancestry or species of origin should be included here as well.

  • What is something Special about them?
    Does any characteristic stand out? Do they have a power or ability unique in this setting? Is there something from their background or upbringing that will benefit them during play?

  • Describe a Flaw about them?
    Do they have any personality traits that hinder them? A bad reputation? Some other quality that could hinder them?

  • What is an important Bond they have to the setting?
    Bonds can be relationships to specific individuals or factions, devotion to a faith or ideology, or even just a special connection to a place.


Skills are broad talents or fields of study the character has proficient study or experience in.

Players write down six Skills, and assign the following array of scores:
+3, +2, +2, +1, +1, +1

This can be written out as a pyramid” — 3 rows of skills, from highest to lowest.

  • +3: Skill
  • +2: Skill, Skill
  • +1: Skill, Skill, Skill


Next, list up to 5 belongings that your character would reasonably have adventuring. Equipment usually doesn’t have a mechanical game function, aside from being a device in the narrative to explain how a character performs an action. With the Guide’s permission, you may spend two of your equipment choices to list a special item that grants Advantage (once per scene) on any rolls associated with its use.

Final Touches

If you haven’t already, give your character a name and maybe a simple description of appearances and mannerisms.
