Scattergories Generator

Free online Scattergories generator. Picks a random letter and a configurable set of categories. Click Start to reveal categories and begin the countdown — buzzer plays when time's up.

Built and maintained by Paul Clark, Redmoon Software

When to use this

Use the Scattergories generator at parties, family game nights, classrooms, or anywhere you want a quick, no-setup vocabulary game. The blurred-categories design means everyone sees the letter at the same moment as the start signal.

How it compares

Most online Scattergories tools just spin a letter and offer one fixed category list. This one lets you vary the category count, difficulty, timer, and letter pool, and blurs categories until Start so the round really begins on cue.

How it works

On page load the generator picks a random letter (A–Z, optionally excluding Q/X/Z) and a configurable number of categories from a curated pool of about 250.

Categories stay blurred until you click Start. That click reveals them and starts the countdown — keeping the suspense of a real Scattergories round even when one device is shared.

When the timer hits zero, a buzzer sounds (Web Audio API, no external file) and a banner appears at the top of the screen. Categories stay visible so you can finish writing down ideas before resetting.

FAQs

How do I play Scattergories?

Each player needs paper and a pen. Everyone sees the same letter and categories. When the timer starts, write down one answer per category that begins with the letter. Score 1 point for any answer no other player matched.

Why are the categories blurred at first?

So the round really starts when you click Start — like a real Scattergories card flip. Otherwise players would have unfair advance time to think.

Why is the buzzer silent?

Browsers block audio until the user has interacted with the page. Once you've clicked Start at least once, the buzzer plays normally.

Can I change the timer?

Yes. Default is 3 minutes (180 sec). Configurable from 30 seconds to 15 minutes.

Why exclude Q, X, Z?

They make many categories nearly impossible. Toggle "Allow Q/X/Z" if your group enjoys hard rounds.

Worked example

Input

Letter: S · 12 categories selected from a pool of ~250.

Output

Categories: Animals · Foods · Movies · Things in a kitchen · Famous athletes · …

The letter and categories are picked when the page loads. Categories stay blurred until you press Start — that's when the 3-minute timer begins. A buzzer sounds when the round ends.

Common pitfalls

  • Rare letters (Q, X, Z) make many categories nearly impossible — keep them disabled unless your group enjoys the chaos.
  • Easy difficulty trends toward concrete categories with many answers per letter; hard difficulty includes abstract and niche topics.
  • The timer continues even if you switch tabs — useful if you want to multitask, but watch the clock.
  • Audio only plays after the first user interaction (browser policy). Tap Start first if the buzzer is silent.

Why the letter matters more than the list

The generator picks a letter and a set of categories. The letter distribution is deliberately not uniform across the alphabet in most versions of the game, because letters like Q, X and Z make nearly every category impossible and produce a round nobody enjoys.

Category difficulty interacts with the letter rather than standing alone: "things in a kitchen" is easy for most letters and hard for a few, while a narrow category is hard for nearly all of them. A good round pairs a workable letter with a spread of category difficulty.

Scoring and the arguments it causes

The standard rule scores one point per unique valid answer and zero for anything another player also wrote, which is what makes obvious answers worthless and rewards thinking sideways.

Almost every dispute is about validity rather than uniqueness: whether a proper noun counts, whether an adjective before the noun ("Red rocket" for R) is legitimate, whether a plural of a previous answer is a new answer. Agreeing those three before starting prevents most of the arguing, and the game is better for having the rules settled in advance rather than adjudicated mid-round.

Scattergories over a long game night: repeated categories, sticky settings, and a clock that can run slow

A single Scattergories round is easy to set up fairly. Ten rounds in a row is a different problem — the category bank runs shallower than you think, the tool remembers last week's settings, and the countdown counts ticks rather than seconds.

Running a fair Scattergories round: letters, categories, and the timer nobody argues with

The classic party game lives or dies on setup. How rare letters, category difficulty, and the length of the timer quietly decide whether a round is fun or a coin flip.
