What's the fastest way to use these guides?

Play one duel first (30 seconds), then look up your numbers: your reaction time's verdict page and your CPS page will mean something immediately.

Are the numbers on these pages real?

They're computed from explicit models — a normal distribution for reaction time (mean 273 ms, SD 60), decay curves for CPS — stated openly on every page that uses them.

Is any of this behind a paywall?

Nothing — the guides, the games, the duels and the leaderboards are all free. The site's only purchase is an optional cosmetic upgrade.

The blocks.pw guides

Everything measurable about being fast, collected: what your reaction time means, what your CPS says about your technique, how to win each mini-game, which game fits which moment, and where your country ranks. All of it free, all of it honest, all of it ending in a duel.
