Jump part of the way towards a random corner, again and again, and a fractal appears out of nowhere – Sierpinski's triangle, then pentagons, then stranger shapes as the rules change.

Jump part of the way towards a random corner, again and again, and a fractal appears out of nowhere – Sierpinski’s triangle, then pentagons, then stranger shapes as the rules change.

In the app you can adjust the points per frame and seconds per rule. It runs natively on your Mac, drawn live in real time – no video, never quite the same twice.

Chaos Game FAQ

How do I set Chaos Game as my screensaver on a Mac?

Install SCRNSVRS free from the Mac App Store, select Chaos Game in the library and click Set as Screensaver. macOS starts it whenever your Mac is idle, exactly like a built-in screensaver.

Can I use Chaos Game as a live wallpaper?

Yes. Click Set as Wallpaper in SCRNSVRS and Chaos Game plays on your desktop behind your windows and icons. You can use it as screensaver and wallpaper at the same time.

Is Chaos Game free?

Chaos Game is included in SCRNSVRS Unlimited. It's free for your first 7 days; after that Unlimited is $1.99/month or $9.99/year (€1.99/month or €9.99/year) for every screensaver, including new ones. It can also come up in Free this month, when 25 premium screensavers are free for everyone.

Is Chaos Game a video loop?

No. Chaos Game is rendered live on your Mac with Metal, so it never repeats and stays sharp on any display size. The clip on this page is a screen recording of the real thing.

Will Chaos Game slow down my Mac or drain the battery?

No. SCRNSVRS drops to 30 fps on battery and stops rendering when the wallpaper is covered by a full-screen app, so Chaos Game costs next to nothing in everyday use.

Which Macs does Chaos Game run on?

Chaos Game needs macOS Tahoe 26 or later.
