Flux

A fast one. Steer your catcher, grab the orbs that match the signal color, and let the wrong ones fall. The signal keeps changing — so must you.

What you'll start when it ends

~90 seconds · move with mouse or ← →

Why it's built this way. This one trains the fast muscles: filtering the signal from the noise, holding back from grabbing the wrong thing, and switching the instant the rule changes. It ramps up to keep you right at your edge — the sweet spot where a restless brain locks in — then hands you your task while you're switched on.
