Is blocks.pw's reaction test the same measurement as Human Benchmark's?

The same fundamental test — milliseconds from a colour change to your input, measured on your device. The difference is format: best-of-5 duels and averaged solo runs instead of single solo attempts.

Which is better for tracking improvement?

Both track well. Human Benchmark gives longer historical charts; blocks.pw gives ELO — a measure that accounts for opponent strength, which raw averages can't.

Can I compare my Human Benchmark score to blocks.pw duels?

Roughly — a ~250 ms Human Benchmark average corresponds to similar duel round times, minus nerves. Check any number's verdict on the is-X-ms-good pages.

The Human Benchmark alternative that fights back

Human Benchmark is the internet's reference collection of cognitive micro-tests — reaction time, sequence memory, aim, number memory — with global percentile charts built from millions of solo attempts. It's clean, free and rightly popular.

What Human Benchmark does brilliantly

The broadest test battery: verbal memory, number memory, typing and more — a fuller cognitive profile than any game offers.
Massive percentile datasets: your score lands on a distribution built from millions of attempts.
A calm, clinical format — no opponents, no pressure, just you and the chart.

What blocks.pw does differently

Every measurement is a duel: reaction, memory and aim rounds run best-of-5 against real people, because a number means more when someone's trying to beat it.
Stakes persist: ranked duels move an ELO rating on country leaderboards — your percentile becomes a rank you defend, not a screenshot.
Challenge links turn any test into a grudge match: send one, and your friend faces the same rounds. Human Benchmark can tell you you're fast; it can't tell you you're faster than Dave.
Solo modes still exist — Reaction, Memory+, Aim 30 — each with a world leaderboard instead of a static chart.

Which should you use?

Use Human Benchmark when you want the full clinical battery and big-data percentiles. Use blocks.pw when the same skills should be contested — duels, rivals, ranks — or when you want your friends' numbers next to yours instead of an anonymous distribution. Many people use both: benchmark solo, settle it here.

The blocks.pw side of the table in one paragraph: 30-second best-of-5 duels, free, no account, no install, challenge links + country elo leaderboards — nine duel mini-games plus solo world records, built to settle things. Judge it in one quick match; it takes less time than reading this sentence took.
