Boom Chicago
Boom Chicago is a high-energy short-form game format in which performers rapidly cycle through a series of very brief scenes or blackouts, each landing on a single joke or comedic moment before cutting to the next. The pace demands instant clarity originating from the performance style of the Boom Chicago theatre in Amsterdam. The game prioritizes speed, economy of language, and the ability to establish and deliver a comic premise within seconds. Each micro-scene functions as a self-contained unit, requiring performers to commit fully to a single idea without the luxury of gradual scene development. The format rewards performers who can generate strong initiations, recognize the comic peak of a premise immediately, and edit themselves before the energy dissipates.
Structure
The host or a designated caller announces a suggestion or theme that will connect the series of scenes. Performers line up on the backline or sides of the stage.
Two or more performers step out and begin a scene. The scene runs only long enough to establish a single comic premise and hit its punchline or moment of peak absurdity. The ideal length for each micro-scene ranges from ten seconds to roughly one minute.
As soon as a scene hits its comic peak, a new pair or group of performers immediately sweeps or edits in to start a fresh scene. There is no pause between scenes. The transition is instantaneous, creating a relentless pace that keeps the audience engaged through constant variety.
The game escalates through the cumulative effect of speed. Early scenes may run slightly longer as the audience acclimates to the format. As the game progresses, scenes become shorter and sharper. The strongest performances build toward a rhythm where scenes land in rapid succession, each topping the previous one in surprise or absurdity.
The game concludes with a blackout after a scene that delivers the strongest comic punch of the set, or when the host calls the game at a natural high point.
How to Teach It
How to Explain It
"Short, fast scenes. Strong initiation: we know who you are and where you are in the first line. When you see the game of the scene, play it. When it is done, it is done. Edit yourself. No dragging, no explaining."
Boom Chicago teaches several foundational improv skills simultaneously: strong initiations, recognizing the game of the scene quickly, and self-editing.
Begin by having performers practice "one-line scenes" in which the entire comic premise must be established and resolved in a single exchange. This strips away the instinct to build slowly and forces performers to lead with their strongest idea.
Progress to two-line and three-line scenes, coaching performers to identify the exact moment a scene has peaked. Ask the group: where did the laugh happen? Everything after that moment is excess.
Coach the backline on aggressive editing. The most common failure in this format is scenes running too long because no one on the backline commits to the sweep. Assign a designated editor in early rehearsals to build the habit of cutting at the peak.
Another common pitfall is performers defaulting to the same type of scene repeatedly: all dialogue scenes, all physical bits, or all callbacks to earlier moments. Coach for range and variety across the set.
The format also builds ensemble awareness. Performers must track who has been on stage, who has not, and what energy the previous scene carried so that the next scene provides contrast rather than repetition.
How to Perform It
The game requires a minimum of four performers to maintain the pace of rapid scene transitions. Six to eight performers is the ideal cast size, providing enough variety to sustain the format without repeating pairings.
Speed is the game's defining characteristic, but speed without clarity produces confusion rather than comedy. Each micro-scene must establish its premise within the first few lines. Performers who spend time building context or layering details lose the audience before reaching the payoff.
The edit is critical. Scenes that run past their comic peak deflate the energy of the entire set. Performers waiting on the backline must watch for the moment a scene hits its highest point and sweep immediately. Hesitating even a few seconds after the peak allows the energy to drop.
Variety in scene content prevents the format from becoming monotonous. Alternating between two-person dialogue scenes, physical bits, character pieces, and direct-address moments keeps the audience guessing about what comes next.
The backline must stay alert and ready. Dead time between scenes breaks the format's momentum. Performers should have initiations prepared and step out with confidence the instant the previous scene ends.
History
The game takes its name from the Boom Chicago theatre in Amsterdam, founded in 1993 by Andrew Moskos and Pep Rosenfeld. Both founders were Americans from Chicago who brought Chicago-style improvisation to the Netherlands. Boom Chicago performs in English and has become one of Europe's premier comedy institutions.
The theatre's performance style, described by Tom Salinsky and Deborah Frances-White in The Improv Handbook as "hugely successful and very slick," shaped the game's emphasis on speed, polish, and audience-pleasing economy. The Second City Chicago and Boom Chicago established an exchange program, facilitating cross-pollination between American and European improv traditions.
Boom Chicago's roster of alumni includes Seth Meyers, Jason Sudeikis, Amber Ruffin, Jordan Peele, and Kay Cannon, all of whom moved from the Amsterdam stage to major careers in American comedy and entertainment. The theatre's emphasis on high-energy, fast-paced performance influenced the development of this game format as a distillation of the Boom Chicago house style into a portable short-form structure.

Related Games
Space Jump
Space Jump is a short-form game in which one performer begins a scene alone. At the call of "space jump," a new performer enters and initiates a completely different scene. When "space jump" is called again, a third performer enters with yet another scene. Eventually the scenes are unwound in reverse order, returning to each previous scene where it left off.
Thunderdome
Thunderdome is a competitive elimination game in which performers face off in rapid head-to-head improv challenges, with the audience determining who advances. The tournament structure builds energy and stakes throughout the show. The format rewards quick wit, fearless performance, and the ability to thrive under competitive pressure.
New Choice
New Choice is a short-form game in which a caller interrupts performers mid-scene by shouting "New Choice," forcing the last speaker to immediately replace their most recent line or action with something entirely different. The caller may fire multiple calls in rapid succession, pushing performers through a cascade of alternatives under pressure. The game trains verbal agility, commitment to offers, and the capacity to abandon choices without hesitation.
