Reaction Time
Ten lights, one at a time, in a random spot on the grid — tap the lit button as fast as you can. Your score is the average across all ten, lower is better; a light you miss entirely costs the full two seconds. One round a day; the streak counts days played, not days won.
How the average is scored
Ten lights, one at a time, in a random spot on the grid. Your score is the mean of all ten in milliseconds and lower is better, so it rewards being consistently quick rather than getting one freakishly fast tap — a single brilliant light is worth a tenth of the result.
A light you miss entirely is scored at the full two seconds, which is a heavy enough penalty that guessing early and hoping is worse than waiting. One round a day; the streak counts days played, not days won.
Signed out: this one needs an account to play. Every round is dealt and settled on the server against a user, so there is no guest version to offer — the overlay dismisses so you can read the page and see what you would be signing up for.
