How is my result scored?

Your first 10 numbers are a warm-up where guesses don't count. After that, your ticket shows your hit rate versus blind guessing (times chance) and how you compare with 206 people from a psychology study in which 418 people each picked 200 numbers from 1 to 9.

Does peeking at the house's guess matter?

Yes. If you peek at the house's pick mid-draw, the house's record stops counting as evidence for the rest of that draw.

Rigged Draw — A split-flap game that out-guesses the numbers you say out l

Specr Lab's 'Rigged Draw' is a free browser-based experiment that tests how random a human can be. You say numbers from 1 to 9 out loud, one after another, while a predictor running in your browser seals its guess for each number before you say it. A split-flap board then shows how far ahead of chance the house gets. At the end, your ticket compares your performance against participants from a psychology study.

Key Features

Live prediction against you

Before each number you say, the house seals its guess in an envelope; once you speak, the envelope opens and the hit is scored on a split-flap board.

Ten concurrent predictors

The house runs ten small predictors at once and trusts whichever has been right lately — some track which number tends to follow which, some track steps up and down, one looks for repeated short sequences, and one notices numbers you haven't said in a while (which does most of the work, since people

Speech recognition in the browser

The page listens to you locally in your browser; a speech pack (~31 MB) downloads once and stays on the device, and your audio never leaves the page.

Typing mode

You can type numbers instead of speaking, but the test is weaker — your ticket marks the draw as typed.

Benchmark against a real study

Your result is calibrated against 418 people who each picked 200 numbers from 1 to 9 in a psychology study; your ticket shows how you compare with 206 people from that study.

Warm-up and peek rules

Your first 10 numbers are a warm-up where guesses don't count, and if you peek at the house's pick mid-draw, its record stops counting as evidence for the rest of that draw.

How It Works

Start the draw

Pick your game (saying vs. typing), download the speech pack if needed, and start the draw.

Say numbers aloud

Say numbers from 1 to 9 out loud, as randomly as you can, speaking clearly; the more numbers you say, the more accurate your result.

Get your ticket

At the end, your ticket shows your hit rate vs. blind guessing (times chance) and how you compare with the psychology-study participants.

Pros & Cons

Pros

Entirely client-side: audio is processed in the browser and never leaves the page
Speech pack is a one-time ~31 MB download that stays on the device
Grounded in real data from a psychology study with hundreds of participants
Includes typing as an accessibility fallback if speech isn't available
Honest scoring rules — peeking at the guess voids the house's record, and typed draws are marked as such

Cons

Who It's For

Best for

Anyone curious how predictable their 'random' choices are
Fans of lightweight browser experiments and psych demos
People who want a private, no-upload activity (audio stays in the browser)

Not ideal for

Serious statistical or scientific research — it's an experiment/game, not a measurement instrument
Users without microphone access or who can't download the speech pack (typing works but is scored as a weaker test)
Anyone expecting a multi-user or competitive online game — it's a solo draw against the house

FAQ

What does the experiment do?

You say numbers from 1 to 9 out loud, as randomly as you can. Before each number, a predictor in your browser seals its guess, and a split-flap board shows whether the house hit and how far ahead of chance it is.

Does my audio get uploaded anywhere?

No. The page listens to you inside your browser, and your audio never leaves the page. The ~31 MB speech pack downloads once and stays on your device unless your browser clears it.

How does the house predict my numbers?

It runs ten small predictors at once and trusts whichever has been right lately. Some count which number tends to follow which, some track your steps up and down, one looks for repeated short sequences, and one notices numbers you haven't said recently — that last one does most of the work.

Can I type instead of speaking?
