Puzzle
Play Stack Purge
Tap matching groups before the rising stack reaches the top.
Flux Sort
Drag falling data shards into the matching channel before the core overflows.
How to Play Flux Sort
- Grab a shard from the core with your finger or the mouse.
- Drag it out to the channel that matches its colour and shape — up, right, down or left.
- Each correct sort buys time. Let the core overflow and the run ends.
Controls
| Keyboard | Not required |
|---|---|
| Touch | Drag a shard from the core into one of the four channels |
Tips
- Clear the shard nearest a full channel first — the core overflows before the clock runs out.
About Flux Sort
Shards pile up in a spinning core. Drag each one out to the channel matching its colour and shape. Every sort buys time, and the core fills faster the longer you last. It runs directly in your browser with no download or sign-up, on desktop and mobile alike.
Frequently Asked Questions
How do you play Flux Sort on a phone?
Drag a shard out of the core with one finger and release it over the matching channel. No keyboard is needed.
What ends a run?
The core overflowing, or the clock reaching zero. Overflow is what usually gets you, so keep the core clear.
What happens if I drop a shard in the wrong channel?
It bounces back into the core and you lose a little time, so a wrong guess costs less than a slow one.
