Puzzle
Play Flux Sort
Drag falling data shards into the matching channel before the core overflows.
Stack Purge
Tap matching groups before the rising stack reaches the top.
How to Play Stack Purge
- Find two or more touching blocks that share a colour and pip count.
- Tap the group to purge it — the blocks above collapse down into the gap.
- Bigger groups score more and buy more time. Let the stack reach the top line and the run ends.
Controls
| Keyboard | Not required |
|---|---|
| Touch | Tap a group of two or more matching blocks |
Tips
- Purge low, not high. Clearing near the floor drops the whole column and buys you room.
About Stack Purge
Rows of blocks push up from below. Tap two or more touching blocks that match and the stack collapses into the gap. Every purge buys time. It runs directly in your browser with no download or sign-up, on desktop and mobile alike.
Frequently Asked Questions
How do I know which blocks match?
Colour and the pip pattern both have to match, so you can still play it if you do not see colour well.
Do bigger groups score more?
Yes, and they buy more time too. A group of six is worth far more than three groups of two.
What ends a run in Stack Purge?
The stack reaching the top line, or the clock running out. The stack is what usually gets you.
