Perceptle Daily: five tests, one challenge each day

Estimate a quantity, predict a ball’s landing, judge an angle, remember a rhythm and place a proportion on a line. Play the daily five-test challenge, or choose Keep playing for fresh random rounds. Each test is scored out of 100.

One date, the same five tests

Play starts the Daily challenge. The calendar date fixes all five tests: the dot count and layout, ball trajectory, target angle and distracting frame, tempo, and line proportion. The same date produces the same puzzle on another browser or device; completed scores stay in the browser that saved them.

Today uses your device’s local calendar date, so players in different time zones can be on different days. The page keeps its date after midnight; refresh to load the new day. Archive recreates the selected date, including that date’s Friday rules.

Five ways to test your estimate

Count asks how many dots appeared briefly. Track asks where a disappearing ball will land. Angle gives you a target in degrees and a handle to drag.

Tempo starts with four different practice beats, then asks you to continue for eight taps without the sound. Split asks for a fraction or percentage measured from a specified end of a line.

Understand the result, then try again

Each test uses a gradual error-based score. A small miss keeps a high score, while larger misses lose points progressively. The full-round total is the rounded average of the five scores, rather than their sum.

Keep playing starts a new random five-test round without waiting for tomorrow. Random Count uses 50–300 dots, and the other targets vary too. Single-test pages repeat one skill. These random attempts do not replace your saved Daily result.

Questions and answers

Can I play more than the daily challenge?

Yes. Play opens today’s fixed challenge or its saved result. Keep playing creates a fresh random round each time, while the practice pages let you repeat one test.

Do I need an account or a download?

No. The game runs in a modern browser on a phone, tablet or computer. Sound is useful for the rhythm test; the game does not request microphone access.
