Comparison codes contain answers and settings. A shared score is self-reported, not proof of who played.
Independent practice scores; no official puzzle parity, percentiles, or verified ranking. Local history is specific to this browser and domain.
Choose skills, difficulty and sets
A standard set contains all five skills. Here you can keep only the ones you want and repeat them over multiple sets. Easy, standard and hard change the generated conditions; normal and Friday change the task itself.
Compare your own results under matching conditions. A higher average in an easy Count-only set is a useful practice result, but it does not mean you beat a full hard Friday set.

What went wrong?
Try this session
Counts are consistently too high or low
Count only, easy or standard. Compare the true count with each estimate.
You lose the ball before it disappears
Track only, easy. Follow the curve; Friday adds reflections.
You confuse the target angle with its direction
Angle on normal first, then Friday to include complete turns.
Your beat drifts once the sound stops
Tempo only. Read offset and jitter separately; Friday uses offbeats.
You mark from the wrong end
Split only. Read the named starting end before each attempt.
