If step 1 fails
If A S D F + Space + Enter cannot be detected cleanly together, you can treat the current result as below 6-key class. This is more common on laptops, membrane boards, and limited matrix zones.

How to read this 2-step result
This page intentionally avoids guessing NKRO from a single peak number. It uses two common combos to give you a practical answer quickly.
If only step 1 passes
That usually means common 6-key combos are fine for daily use and many games, but heavier simultaneous combos can still lose keys.
If both steps pass
That means the current browser path already shows strong simultaneous input behavior. For most users, that is enough to call the keyboard good at multi-key holds.
NKRO FAQ
These are the core rules behind the simplified verdict on this page.
Q.
Why not say “your keyboard is NKRO” directly here?
Because this page measures what the browser actually receives. It is excellent for practical self-checks, but it is not the same thing as laboratory-style hardware certification, so “high-rollover behavior” is the more honest label.
Q.
Does a laptop or membrane keyboard automatically rule out strong rollover?
No. They do hit zone limits more often, but the real deciding factors are still the matrix, controller, and firmware, not the switch category alone.
Q.
Why not judge the result by the maximum simultaneous key count only?
Because a single peak only tells you how many keys the browser saw in one moment. It does not prove that common real-world combos pass cleanly every time. The fixed 2-step combos are easier to trust.
Q.
What if step 2 feels awkward to press?
That step is only a stress check. Try it as “left hand on A S D F, right hand on H J K L, then add Space and Enter.” One clean full hit is enough to count as passed.
