How to play Scream Jump
Make a noise and your character climbs. Go quiet and it drops. Shout, hum, sing or whistle your way through the gaps — a genuinely funny party game that runs in your browser with nothing to install.
Play Scream JumpScream Jump reads the loudness of your microphone and turns it straight into lift. A steady hum holds a steady altitude, a sudden shout sends you up fast, and silence drops you. That one rule is the whole control scheme, which is why it works so well with a room full of people and why children work it out instantly.
The game calibrates to your room before each run, measuring the background noise for a moment so a noisy café and a silent bedroom both play fairly. A live meter shows exactly what the microphone is picking up, so it never feels like the game is ignoring you.
Your audio is analysed entirely inside your browser and is never recorded, uploaded, stored or sent anywhere — the game only ever looks at a single number, how loud the input is right now. If you would rather not grant microphone access, or you are somewhere you cannot make noise, the game plays identically by holding your finger on the screen instead.
It needs no download and no account, and works on phones, tablets and computers. Note that microphone access requires a secure connection, which this site uses.

How it works, step by step
- 1
Allow the microphone
Tap Use my voice and accept your browser's microphone prompt. Prefer not to? Choose the touch mode instead — it plays exactly the same.
- 2
Wait for calibration
The game listens to your room for a moment to learn its background noise level, so it is not fooled by a noisy environment.

Frequently asked questions
Is my voice recorded or uploaded?
No. The audio is analysed live in your browser and never leaves your device — nothing is recorded, saved, uploaded or sent to a server. The game only reads how loud the input is at each moment.
Can I play without a microphone?
Yes. Choose touch mode and hold your finger on the screen to climb. It is the same game with the same scoring.
Why does the game need microphone permission?
Loudness is the control. Browsers require your explicit permission before any page can read microphone input, and that permission is only requested when you tap Use my voice.
It is not responding to my voice — what is wrong?
Check that you granted microphone permission, that the right input device is selected in your system settings, and that the on-screen meter moves when you speak. Recalibrating in a quieter spot also helps if the room is very loud.
Does it work on iPhone and Android?
Yes, in a modern mobile browser over a secure connection. On iPhone you may need to tap once to start audio, which the game's start button already does.
Is Scream Jump free?
Yes. It is completely free, with no sign-up, no download and no purchase.
Free, no download and no sign-up. Works on phone and desktop.
