Track

Boards appear, you loose arrows. Every tap scores by the ring it lands in — bullseye 10, out to 4, wide is nought — and the board moves on either way. It’s the speed-versus-precision trade-off movement scientists have studied since the fifties, scored like an archery round: no misses, just worse arrows, on a thumb and a mouse alike.

Hand–eye speed is trainable and shamelessly warm-up-sensitive — cold hands post terrible groupings, which is your excuse ready-made. Ring scoring keeps the test honest across devices: a thumb’s wobble and a cursor’s overshoot cost the same points. The real opponent is still yesterday’s you. Warm hands travel well: take them to Max Out in the arcade, browse the exercise library for the agility work behind the reflexes, or race Reaction and Recall back in the Lab.
