Timed accuracy

Sweet Spot

Standard mode scatters two to six dials across the field at once, each needle spinning at its own speed between half and a full rotation per second, from its own starting position. Click a dial while its needle is inside the coloured arc to score a point; a click outside the arc costs one, and so does letting a dial expire unresolved. Dials live for four to nine seconds, every arc is between 25 and 45 degrees wide, and the field fills up as the two minutes run, so the late game rewards genuine needle tracking over hopeful clicking. Work one dial at a time and give the slow dials priority: their windows come around rarely, so missing one is expensive.

Session

Two minutes of spinning dials, each needle at its own speed. Click inside the coloured arc to score; misses and expired dials cost a point, and the field fills up as the clock runs.

How it works

Rotating dials appear and disappear for two minutes, each with a needle sweeping at its own speed and a coloured target arc. Click a dial while its needle is inside the arc: a hit scores a point, a click outside the arc costs one, and a dial that expires without a hit costs one more.

Work one dial at a time

Commit to a dial and complete it. Splitting attention across two rotating needles produces worse results than working them in sequence.

Prioritise slow dials

A fast needle brings its window around again quickly, so missing it is cheap. A missed window on a slow dial is expensive.

Lead the needle

Click slightly before the arc rather than on it, so your input latency lands the click inside the window.

Frequently asked questions

What is Sweet Spot?
Sweet Spot is the dial-timing game from gamified cognitive batteries. Rotating dials appear and disappear across a two-minute session, each with a needle spinning at its own speed and a coloured target arc. Clicking a dial while its needle is inside the arc scores a point; wrong-moment clicks and expired dials cost one. It measures timed accuracy against multiple independent moving targets, which is what separates it from a plain reaction test.
How does the scoring work?
A hit is worth one point. Every click that lands outside a dial’s arc costs a point, background clicks included, and every dial that expires without a hit costs one more. The score can go negative. Each hit also records how far the needle was from the centre of the arc, and that angular error is reported alongside the score.
Why does every dial spin at a different speed?
Per-dial needle speed is the core mechanic. With every needle sweeping at its own rate, between half and a full rotation per second, and starting from its own position, no single timing rhythm works across the board: you have to track each target on its own. Arc widths vary from 25 to 45 degrees dial by dial, and more dials share the field as the session runs, so the attention demand rises with the clock.
What is the best strategy?
Commit to one dial at a time and complete it; splitting attention across two rotating needles produces worse results than working them in sequence. Give slow dials priority: a fast needle brings its window around again quickly, so a missed window there is cheap, while a missed window on a slow dial is expensive. And lead the needle: click slightly before the arc rather than on it, to absorb input latency.
What do the results measure?
Three things, reported separately: your score, your hit rate across resolved dials, and your mean angular error at the moment of each hit. Angular error is the interesting one: it separates players who genuinely time the needle from players who click-spam and get lucky. Dials that expired without any click attempt are tracked too, because leaving a target untouched is an attention failure rather than a timing failure.
