About me

I initially created this site purely for myself to record satisfying content for my YouTube channel. However, my videos started getting traction, and so many people in the comments kept asking what tool I was using to generate these visuals. Because of the overwhelming demand, I decided to polish the code, add a beautiful UI, and make this physics simulator available to anyone who wants to create their own viral videos!

Guides & modes

Simulation modes

Each mode is a different kind of satisfying. Every loop below is recorded straight from the app.

Free

Standard

Your sandbox: gaps, spikes and up to five walls that turn together. Tune every detail until the clip looks exactly the way you imagined.

Try it free

Free

Spikes Popular

The walls are lined with spikes, so the ball gets impaled instead of bouncing. The next one ricochets off the balls already stuck — every attempt takes a new route.

Try it free

Free

Timed Freeze

Every ball has a few seconds to escape. Run out of time and it freezes on the spot — the frozen ones pile up into obstacles that reshape the arena.

Try it free

Free

Multiply

Every escape spawns two new balls. What begins as one calm ball turns into total, deeply satisfying chaos.

Try it free

Pro

Line War Popular

A war between balls, fought with lines. Cut through another ball's line and it becomes yours; the last ball standing takes the win.

Open with Creator Pro

Pro

Spiral Beta

Balls roll down a spiral and drop into multiplier zones: land in ×5 and one ball becomes five, while the count explodes.

Open with Creator Pro

Free

Growth

The ball grows with every bounce until it turns into a wall, then the next one starts. Pick your own picture or video and watch the walls slowly build it.

Try it free

Pro

Black Hole New

A black hole pulls every ball in, eats it and grows. Only the balls that slip out through the gap are saved — name them and let your viewers guess who survives.

Open with Creator Pro

Pro

Dropper New

Balls pour into a ring, and two of a kind merge into the next, bigger one. Give every size its own picture, GIF and sound.

Open with Creator Pro

Standard, Spikes, Timed Freeze, Multiply and Growth are free. Line War, Spiral, Black Hole and Dropper come with Creator Pro.

The appeal

Why these clips work

Simple physics, endlessly satisfying to watch.

Never the same twice

Shape the gameplay however you like — gravity, wall size, colors, custom photos and sounds. Every setup plays out differently, so you can post a whole series without repeating a single clip.

Built to be satisfying

Smooth physics, glowing trails and clean escapes lean into the same simple, repetitive visuals that make ASMR-style content so watchable.

Your own audio layer

Import your own SFX or music track on Creator Pro and pair it with the bounces for a satisfying audio-visual loop.

1. Acceptance & Scope

These Terms of Service govern your access to and use of Satisfying Labs, a platform for generating original physics-based visual simulations for content creation (TikTok, YouTube Shorts, Instagram Reels, and similar platforms). By creating an account or otherwise using the Service, you accept these Terms in full.

2. Eligibility & Your Account

You must be at least 16 years old to create an account. If you are under 18, you confirm that a parent or legal guardian has authorized your use of the Service. You are responsible for keeping your login credentials secure and for all activity that takes place under your account.

3. Subscription Plan & Billing

Access to premium features is provided through the Creator Pro subscription, available on a monthly, 6-month, or 12-month billing cycle, as selected at checkout. Each subscription renews automatically at the end of its cycle at the rate then in effect, unless cancelled beforehand. Up-to-date pricing for every cycle is always listed on our pricing page.

Welcome offer. A new account can start the monthly plan at a reduced price for its first three months of subscription (the price shown at checkout, instead of the regular monthly price). The offer can be claimed within three months of creating the account and is available once per account; it is not available to accounts that have already had a subscription. When the three discounted months end, the subscription renews automatically at the regular monthly price shown at checkout, unless you cancel beforehand.

4. Cancellation & Refunds

You can turn off auto-renewal at any time from your account dashboard; once cancelled, your access simply continues until the end of the period you already paid for. Because the Service grants immediate access to digital content upon payment, fees already charged are not refundable, and by completing a purchase you agree to waive any statutory withdrawal period available for digital goods, where permitted by law.

5. Ownership & Usage Rights

The simulation software, rendering logic, and underlying source code remain the exclusive property of Satisfying Labs. You may not decompile, reverse-engineer, or otherwise extract that logic to build a similar or competing product. In turn, subscribing grants you a non-exclusive, worldwide right to use, publish, and monetize the videos you personally generate through the Service, including commercially. Redistributing raw, unedited export files as a standalone product or asset pack is not permitted.

6. Imported Audio & Third-Party Rights

If a feature of the Service lets you add your own audio or MIDI tracks, it is your responsibility to make sure you're entitled to use that material. Satisfying Labs cannot be held responsible for copyright claims, platform strikes, or demonetization triggered by audio you chose to include in your videos.

7. Availability & Limitation of Liability

We work to keep the Service reliable but do not guarantee uninterrupted access, as occasional downtime for maintenance or technical reasons may occur. Satisfying Labs is a creative tool only; we have no control over, and accept no liability for, decisions made by third-party platforms regarding the reach, monetization, or removal of content you publish there.

8. Suspension & Termination

Where a user seriously breaches these Terms — in particular the ownership and usage restrictions in Section 5 — Satisfying Labs may suspend or close the account involved. Wherever practical, we'll aim to notify you first and give you a chance to resolve the issue; fees already paid for the affected period are not refunded in such cases.

9. Changes to These Terms

These Terms may be updated periodically to reflect changes to the Service or applicable law. We'll post the revised version here with a new "Last updated" date; continuing to use the Service afterward means you accept the changes.

10. Getting in Touch

Questions about these Terms are welcome via the Contact form or at [email protected].
