Practice the five Friday variants
Friday changes how each familiar test works. This practice page lets you try those variants on any day, with new generated targets and the same five-test sequence. Read each brief before acting, because the normal shortcut may no longer apply.
Moving quantities and reflected flights
Count’s dots drift and bounce during an exposure of about 2.6 seconds. Keep track of the quantity rather than counting a dot again when it moves.
Track uses weaker gravity and live side walls. The path can ricochet before landing, so extend the reflected flight rather than assuming it continues beyond the wall.
Full turns, offbeats and extended lines
Angle asks for accumulated rotation between 400° and 1040°. Continue winding past a full revolution and use the spiral as a guide to completed turns.
Tempo first uses loud beats and quiet in-between guides; after calibration, continue on those in-between positions. Split asks for more than one whole line, so the target lies beyond an end.
- Read the changed instruction before pressing Ready.
- Keep counting full rotations in Angle.
- Treat an offbeat as the middle between loud beats.
- For an improper fraction, extend the line mentally.
Compare a variant with its own tolerance
The more demanding variants use wider error scales, while all scores still run from 0 to 100 and decrease gradually. A full round averages the five scores.
Friday rounds generate fresh targets each time. Use individual test pages to understand a normal mechanic before returning to its Friday variation.
Questions and answers
Must I wait until Friday?
No. This page launches the Friday variations on any day. Dated archive puzzles follow their own calendar rules.
Why does one missing turn matter?
The Friday angle task includes the number of completed turns. Matching only the final direction leaves part of the instruction unanswered.
