Null Cascade
Tap the falling packets before they breach your firewall — but not the sealed ones.
How to Play Null Cascade
- Tap a falling square to null it before it reaches the firewall line.
- Armoured packets show extra outlines and need more than one tap.
- Circles with a tick are sealed traffic — tapping one costs you. Let them land.

Tips
- Let a packet fall into the hatched band before you tap it. It pays double, and you still have time if you commit early.
About Null Cascade
Corrupted packets fall toward your firewall. Tap one to null it before it lands. Armoured packets take more than one hit, and sealed traffic must be let through. It runs directly in your browser with no download or sign-up, on desktop and mobile alike.
Frequently Asked Questions
Which packets should I not tap?
The circles with a tick through them. They are sealed traffic, and nulling one costs firewall integrity.
Why did one packet take two taps?
It was armoured. The concentric outlines show how many layers are left, so you can see it before you commit.
Does letting a packet fall further help?
Yes. Nulling inside the hatched band near the floor pays double, but you get one chance at it.
