Quick answer: Freeform Universal (FU) is a free, rules-light tabletop roleplaying game written by Nathan Russell and published by Peril Planet. Instead of numbers, you describe your character with short phrases. When the outcome of an action is uncertain, you ask a yes-or-no question and roll a six-sided die to answer it. It works in any genre, and the classic rules are free to download from Peril Planet’s website.
This guide explains how FU plays, how the dice work, how to build a character, which edition to pick and where to get the rules. It is based on the official rulebook and Peril Planet’s own pages.

What is Freeform Universal?
Freeform Universal is a tabletop roleplaying game built for fast, low-preparation play. “Freeform” refers to the loose, descriptive way characters are made. “Universal” means the rules are not tied to one setting, so the same system can run a space chase, a haunted house or a fantasy quest.
“FU” is short for the full name. Nathan Russell has said he has always pronounced it “foo”.
To play, you need:
- At least one six-sided die. Around three per player is more comfortable.
- Pencil and paper for character notes.
- Two or more people. Most players run one character each, and one person acts as the Narrator (the game master).
The rulebook assumes at least one person at the table already knows roughly how roleplaying games work. It suits groups who prefer making things up as they go over reading long rules.
| Figure | What it tells you |
|---|---|
| 0 | Numerical stats on a character sheet |
| 4 | Descriptors per character: Body, Mind, Edge and Flaw |
| 2 | Pieces of Gear per character |
| 1 | Minimum number of dice needed to play |
| 6 | Possible answers to every roll |
| 10,000+ | Downloads since 2010, as reported by the publisher (not independently audited) |
Who created Freeform Universal?
Nathan Russell wrote FU and publishes it through his studio, Peril Planet. The classic rulebook says he finished the game as part of National Game Design Month in 2010. It has since built a community of players and “hackers” who adapt the rules for their own games.
| Date | Milestone |
|---|---|
| 2010 | FU completed during National Game Design Month and released |
| 2020 | “Classic update” rules PDF and a second edition beta (v1.1, October 2020) available |
| 2026 | Peril Planet’s FU page still live and updated (last modified 6 October 2026) |
How does a game of FU work?
Play is a conversation. Everyone agrees the type of story first, then the Narrator sets a scene and players say what their characters do. Dice only come out when the result is not obvious.
What the Narrator does
The Narrator describes scenes, plays every non-player character and presents obstacles. Because only players roll dice, the Narrator is free to plan the next twist. The rulebook’s main advice is to keep things simple, say “yes” to good player ideas and only ask for a roll when any result would make the story more interesting.
Scenes and turns
A scene is one chunk of story with a clear objective. When the order of actions matters, such as in a fight, the scene can be split into turns where each character takes one action. Turns are optional.
How the Freeform Universal dice system works
FU uses one type of roll for everything, called the “beat the odds” roll. You roll a d6 and try to get an even number. Higher is better within each group, so a 6 is the best result and a 1 is the worst.
Step 1: ask a closed question
A closed question has only a yes or no answer. The roll answers it. Often you do not need to say the question out loud because the action makes it obvious.
| Works well (closed) | Does not work (open) |
|---|---|
| “Do I leap the chasm?” | “What happens when I jump?” |
| “Do I disarm my opponent?” | “How do I fight him?” |
| “Does the guard believe my story?” | “What does the guard think?” |
Step 2: read the six possible answers
| Die roll | Answer | What it means |
|---|---|---|
| 6 | Yes, and… | You get what you want, plus something extra |
| 4 | Yes… | You get what you want |
| 2 | Yes, but… | You get what you want, at a cost |
| 5 | No, but… | You do not get it, but it is not a total loss |
| 3 | No… | You do not get what you were after |
| 1 | No, and… | You fail and things get worse |
Because the six numbers split evenly, a single die gives a 50% chance of a “Yes” and a 50% chance of a “No”. Each of the six answers comes up one time in six (about 16.7%).
What “and” and “but” do
Yes and No tell you whether the action worked. “And” and “but” add a twist. When you get one, the table agrees an extra fact, which can be either:
- A Condition on a character, such as angry, confused, tired or injured.
- A Detail in the scene, such as curtains catching fire, a window breaking or a gap appearing in a hedge.
Anyone can suggest the twist, but the Narrator has the final say. Conditions and Details can then feed into later rolls as bonuses or penalties.
Step 3: add bonus and penalty dice
FU has no stats to add up. Instead, you change how many dice you roll:
- Easier: roll one extra die for each Descriptor, piece of Gear, Condition or Detail that helps. You choose the single best die. Best means the most useful result, not always the highest number.
- Harder: roll one extra die for each factor that hinders you. You must keep the single worst die.
- Cancelling: one helpful factor cancels one hindering factor, so you never roll both kinds at once.
The effect on your odds is large. This chart shows the chance of any “Yes” result for each net number of bonus or penalty dice. These figures are my own calculation from the official rules, ignoring the optional matching-dice rule.
The maths is simple. With bonus dice, you get a Yes unless every die is odd. With penalty dice, you only get a Yes if every die is even.
FU Points: the extra resource
FU Points are a reward for doing something cool, funny or well roleplayed. You can spend them in two ways:
- Before the roll: add one bonus die per point.
- After the roll: re-roll one die per point. A re-rolled die cannot be re-rolled again.
The rulebook suggests starting with about two points for high-adventure games, three for super-powered heroes and one or none for grittier stories. It also lists optional variants, such as spending a point to adjust a die by one pip.
A worked example
Maya plays a smuggler pilot. A patrol ship is chasing her through an asteroid field.
- Question: “Do I lose the patrol ship?”
- Factors: Her Edge, Fly Anything, helps (+). The dense asteroids give cover, a helpful Detail (+). Her Battered Skiff is slow, which hinders (−). One cancels out, leaving a net +1.
- Roll: two dice (one extra). She rolls a 3 and a 4 and keeps the 4.
- Result: “Yes…”. She loses the patrol ship, and the scene moves on. Had she kept a 2, it would have been “Yes, but…”, so she escapes with a damaged engine (a Condition).
Two optional rules are worth knowing. The rulebook offers a flatter chart for groups who prefer 1–3 as bad and 4–6 as good. It also has a matching-dice rule, where doubles or triples add an extra “and” to the result.
How character creation works in Freeform Universal
Making a character takes a few minutes. You follow six steps, and none involve numbers.
- Concept: sum up who the character is in a few words, such as “paranormal detective”. Clichés are encouraged because everyone understands them instantly.
- Descriptors: choose one each for Body, Mind, Edge and Flaw.
- Gear: choose two items.
- Description: add a name, appearance, history and personality.
- Drives: decide what your character wants, what is stopping them and what they will do about it.
- Relationships: write a short link to at least one other character. Two is a good starting number.
Descriptors: replacing stats with words
Descriptors are adjectives or very short phrases. They guide your roleplaying and, when relevant, give you a bonus die. Good ones are clear, innate (part of the character, not an item) and narrow enough to have one or two obvious uses. “Medicine” is a better Edge than “Doctor”, for example, because “Doctor” could be stretched to cover almost anything.
| Descriptor | What it covers | Official examples |
|---|---|---|
| Body | Physical traits | Agile, Strong, Tall, Weak |
| Mind | Mental traits | Observant, Book-Smart, Witty |
| Edge | A skill or special ability | Driving, Fencing, Medicine |
| Flaw | A weakness that causes trouble | Clumsy, Greedy, Smelly |
The rulebook’s advice for Edges and Flaws is to make Edges the sort of thing other games call skills, and to make Flaws personality traits or physical shortcomings. “Reckless” or “deaf” is a better Flaw than “can’t drive”.
Gear, Drives and Relationships
Gear is equipment that can be lost, broken or stolen. Each item is written as one adjective plus a noun, such as “Sharp Sabre” or “Fast Motorcycle”. An item with a built-in drawback, like a “Broken Dagger”, is more interesting than a plain one. Anything not listed as Gear is a prop and gives no bonus.
Drives and Relationships do not change dice rolls directly. They give you reasons to act, and the Narrator may occasionally award a bonus for them. Avoid Drives or Relationships that put characters at each other’s throats, because the group needs to work together.
| Part of sheet | Example: Maya, smuggler pilot |
|---|---|
| Concept | Smuggler pilot |
| Body | Wiry |
| Mind | Quick-Witted |
| Edge | Fly Anything |
| Flaw | Reckless |
| Gear | Battered Skiff, Forged Permit |
| Drive | Wants to clear a debt; a rival crew is hunting her; she will take risky cargo jobs |
| Relationship | Former co-pilot of the ship’s engineer |
How characters improve
FU is not a levelling game. In the classic rules, a player can change one Descriptor between sessions to reflect what happened in the story, and Gear can change at the Narrator’s discretion. Goals can also be updated at the start of each session. Peril Planet has blogged about an optional experience-points system, but it is not part of the classic rules.
What genres can you play with Freeform Universal?
Any genre works, because the rules contain no setting. You choose the genre, then write Descriptors and Gear that suit it. The rulebook even suggests a quick way to start: each player writes two genres on slips of paper, you draw two from a hat and mash them together, such as “Medieval Super-heroes”.
| Genre | Sample Edge | Sample Flaw | Sample Gear |
|---|---|---|---|
| Fantasy | Fencing | Greedy | Rusting Sabre |
| Science fiction | Fly Anything | Alien Perspective | Exotic Robes |
| Cyberpunk | Computer Hacking | Wanted | Cracked Visor |
| Superhero | Super Strength | Short-Tempered | Patched Cape |
| Mystery or horror | Arcane Knowledge | Poor Sight | Water-damaged Notebook |
| Pulp adventure | Use Bull Whip | Afraid of Heights | Worn Leather Jacket |
Films and series are a handy shortcut for getting everyone on the same page about tone. For space adventure, you could watch the Star Wars films and shows in order to pick up ideas for scenes and villains. For superheroes, the Marvel films in story order, Batman’s long history on the big screen and the Superman TV shows show how very different tones can share one genre.
The official starter adventure, “Race to the Temple of Tot”, is pure pulp in the style of Indiana Jones. If that tone appeals, the classic films you can stream in the UK are a good place to find it. For detective or horror games, true crime documentaries available in the UK offer plenty of real-world mystery structure to borrow.
Freeform Universal Classic vs second edition beta
There are two official versions you can download from Peril Planet. For a first game, start with Classic.
| Feature | FU Classic | FU 2nd Edition Beta |
|---|---|---|
| Status | Complete, published rules (2020 update PDF) | Unfinished beta (v1.1, October 2020) |

Peril Planet’s author blog also discusses optional ideas such as tags and trademarks, plus experimental rules for weapons, armour and hit points. These are described as optional or untested, so treat them as extras.
Is Freeform Universal free? The licence explained
Yes, the classic rules are a free download from Peril Planet. They are also released under a Creative Commons Attribution 4.0 licence (CC BY 4.0). In plain English, that means you may:
- Copy and share the rules.
- Remix, edit and build your own game or setting from them.
- Do so commercially, as long as you credit Nathan Russell, link to the licence and say if you made changes.
You should not suggest that the author endorses your version. The licence covers the rules text, so check the credits on any third-party artwork before reusing it. Always read the licence terms before publishing anything.

Freeform Universal vs other tabletop RPGs
These games solve the same problem in different ways. None is better for everyone.
| Game | Core roll | Characters | Complexity | Setting |
|---|---|---|---|---|
| Freeform Universal | One or more d6, keep best or worst, even is good | Descriptors and Gear, no numbers | Very light | Any |
| Dungeons & Dragons | d20 plus modifiers | Classes, levels and numeric stats | Heavier | Fantasy by default |
| Fate Accelerated | Four Fate dice plus an approach | Aspects and approaches | Light to medium | Any |
| Lasers & Feelings | d6s against a single number | One number and a short style | Very light | Space adventure |
| Risus | d6 pools | Clichés rated by dice | Very light | Any |
| FUDGE | Fudge dice | Trait ladder | Toolkit, needs setup | Any |
The closest in spirit to FU is the group of very light, narrative-first games. The big difference is FU’s six-answer chart. Each roll tells you not just whether you succeed, but also how the story twists.
Is Freeform Universal right for you?
| Strengths | Limits |
|---|---|
| Learn it in minutes | Needs players who are happy to improvise |
| Low preparation for the Narrator | Some players want detailed tactical rules |
| Works in any genre | “And” and “but” results need creative interpretation |
| Free and open to adaptation | Little official long-term campaign support in the classic rules |
Verdict: FU suits beginners, one-shots, pick-up games and groups who find big rulebooks off-putting. If your table loves detailed combat options or character builds, a more structured game will probably feel better.
Solo play, hacks and related games
Can you play Freeform Universal solo?
Solo play is not an official mode. The classic rules assume a Narrator. However, the system is a natural fit for solo adaptations because it runs on yes-or-no questions. Many players act as both player and Narrator and use random prompts to set scenes. Treat this as a community approach, not an official rule.
Hacks and translations
A “hack” is a fan-made variation of the rules. Because of the CC BY licence, many exist, and Peril Planet keeps a page of them. The German edition shows how the same licence supports translations.
Games that are not FU
- Other Peril Planet games: Nathan Russell also publishes titles such as Neon City Overdrive and Dungeon Blitz. Check each product page to see how its rules relate to FU.
- FUN (Freeform Universal Narrative): a separate game by Mighty Six Enterprises that borrows from FU. It is not published by Peril Planet.
- FUDGE: an older, unrelated system whose name stands for “Freeform, Universal, Donated Gaming Engine”.
- Freeform TV and Universal Pictures: no connection. The words match by coincidence.
Freeform Universal FAQs
What does FU stand for?
FU stands for Freeform Universal. The author pronounces it “foo”.
What dice does Freeform Universal use?
Standard six-sided dice. You need at least one, and about three per player is more comfortable.
Does Freeform Universal use stats?
No. Characters are described with Descriptors and Gear. These change how many dice you roll rather than adding numbers.
Who rolls the dice?
Only the players. The Narrator does not roll, and there are no opposed rolls. The opponent’s strengths are counted as bonus or penalty dice on the player’s roll.
Is Freeform Universal good for beginners?
Yes, with one caveat. The rulebook assumes at least one person at the table has played a roleplaying game before.
Can I run a long campaign in FU?
Yes. Characters change by swapping a Descriptor between sessions and updating goals, not by levelling up. The classic rules focus on quick, low-prep play.
What is the difference between FU Classic and FU 2e?
Classic is the finished, short rulebook. The second edition is a longer, unfinished beta that the author says may change a lot.
Is Freeform Universal the same as FUDGE?
No. They are separate games with different rules, even though FUDGE’s full name includes the words “Freeform” and “Universal”.
Final thoughts
Freeform Universal is one of the quickest ways to start roleplaying. You need one die, a few words per character and a willingness to make up the story together. Download the short Classic rules from Peril Planet, make a character in five minutes and ask your first closed question.
