Three Rules
Three Rules is a scene exercise in which the facilitator establishes three specific constraints that performers must maintain throughout their scene. The constraints can be physical (always touching the wall, never letting your hands go below your waist), verbal (never using the letter S, only asking questions), or behavioral (treat your partner as royalty, move as if underwater). The exercise demonstrates that limitations generate rather than restrict creative choices, and trains performers to divide attention between scene work and rule compliance.
Structure
Setup
The facilitator announces three rules before the scene begins. Rules should be specific, observable, and checkable: performers must be able to tell whether they are following each rule at any moment. Vague rules ("be interesting") are not useful; concrete rules ("never sit down") are.
Rules can be drawn from different categories:
- Physical rules: always maintain contact with a piece of furniture; never face upstage; keep one hand on your head
- Verbal rules: never use the word "and"; start every sentence with the same letter; only speak in questions
- Behavioral rules: treat your partner as infinitely fragile; behave as if the room is extremely cold
Exercise
The scene begins. Performers play a normal scene while simultaneously complying with all three rules. When a rule is violated, the facilitator may call it out, ask the performers to continue and debrief at the end, or use the violation as a teaching moment mid-scene.
Variation
Rules can be added mid-scene one at a time as the exercise progresses, gradually increasing cognitive load. In this version, performers adapt to each new constraint as it is introduced rather than beginning with all three.
How to Teach It
How to Explain It
"We are going to play a scene, but with three rules. Each rule constrains how you can behave: no sitting, everything said must be a question, no one may speak first. I will tell you the rules before we start. The scene must obey all three. Begin."
Objectives
Three Rules trains divided attention: performers must track scene work (relationship, character, story) while simultaneously monitoring compliance with each active rule. The exercise reveals which scene-work skills are automated and which still require conscious attention. A performer who cannot manage one rule alongside scene work has not yet internalized the foundational scene skills that the rule disrupts.
Choosing Rules
The most useful rule sets combine constraints from different domains: one physical, one verbal, one relational. Stacking three rules from the same domain (three verbal constraints) creates a very high load in one channel; mixing domains distributes the cognitive demand.
Avoid rules that stop the scene: "always face away from your partner" makes scene work impossible and teaches performers to manage the rule at the scene's expense rather than integrating it. Rules should create friction, not paralysis.
Debriefing the Exercise
The most productive debrief question is: which rule was hardest to remember? The answer reveals which scene-work channels are most demanding for each performer. A performer who forgot the physical rule but maintained the verbal rule has automated physical awareness more fully than verbal awareness. This information is diagnostically useful for the next phase of training.
The Paradox of Constraints
The exercise demonstrates experientially that constraints are generative: performers who are required to never sit down, never say "no," and always move in slow motion often produce more inventive choices than performers playing without rules, because the constraints force solutions that would not have been attempted in an unconstrained scene. Debriefing this observation connects the exercise to a broader principle about the relationship between limitation and creativity.
History
No specific originator of the Three Rules exercise format is documented in published improv sources. The pedagogical principle that constraints generate creativity has deep roots in the game-based approach to actor training developed by Viola Spolin: many of Spolin's games involve a specific physical or verbal rule that performers must maintain during a scene, with the rule serving both as a focus point and as a generative limitation.
The exercise appears in the curricula of many improv programs under different names. The concept of imposing simultaneous constraints on a scene as a training tool is common enough across improv pedagogy that no single point of origin has been established.

Related Exercises
Move On
Move On is a scene exercise in which a facilitator calls out the directive to prompt performers to abandon their current scene beat and transition immediately to a new choice. The call forces performers to leave comfortable territory and advance the scene rather than circling the same material. The exercise builds editorial instincts about when a moment has been fully explored and trains the habit of moving forward rather than sideways. It develops the internal sense of pacing that distinguishes dynamic scene work from repetitive scene work.
Three Line Environment
Three Line Environment is an exercise in which performers establish a complete physical world using exactly three lines of dialogue, each line adding a distinct environmental detail. The constraint forces precise, economical world-building and develops the skill of grounding a scene in a specific location through implication rather than announcement.
Annoyance Scenes
Annoyance Scenes is an exercise rooted in the Annoyance Theatre tradition of finding the truth in aggressive, high-energy play. Performers practice scenes in which characters pursue strong wants with unapologetic directness. The exercise builds confidence in making bold choices and playing at the top of one's intelligence.
Play With
Play With is a scene exercise in which performers are directed to explore and heighten whatever elements have already emerged in a scene rather than driving toward a predetermined outcome. The coaching directive -- "play with it" -- asks players to treat each established detail, character behavior, or game pattern as material to revisit, expand, and discover rather than move past. The exercise trains the improv muscle of finding satisfaction in the present moment of a scene.
Simple Continuation
Simple Continuation is a scene exercise in which a facilitator starts a scene with a basic premise and the performers continue from that point, practicing the skill of receiving an offer and building on it without the pressure of initiating from scratch.
Lcd
LCD (Lowest Common Denominator) is a scene exercise in which performers practice finding the simplest, most universal emotional truth in a scene rather than reaching for clever or complicated choices. The exercise trains the instinct to ground scenes in recognizable human experience. It rewards simplicity over sophistication.
