Five tiny tests of visual instinct. An independent daily game.
Instinctle is an independent daily perception game. Point, drag, and tap your way through five original tests, then share a spoiler-free score out of 500. A new set arrives at midnight, US Eastern Time.
Five tests, one total.
Full instructions ↗Crossing, Stretch, Vanish, Between, and Aftertone, always in that order. Each scores up to 100, for a total out of 500. A new set arrives at midnight, US Eastern Time. Practice in unlimited mode whenever you like — it does not change your daily score or streak.
An original daily, not a copy
The five tests were designed for this site: a hidden intersection, a path-length match, a vanishing point, a time midpoint, and a simultaneous-contrast lightness match. They are abstract geometry and light, never photographs of real objects, and never someone else’s item bank.
Instinctle is not affiliated with, endorsed by, or a copy of Perceptle, Freehand, or any other perception game. It is an independent project with its own rules, scoring, and visual style. If you arrived looking for a game like Perceptle, you are in the right neighbourhood and on a different street — read the comparison page if you want the differences spelled out.
How this sits next to Howbigle
Howbigle, from the same operator, asks how large a real object is, using published measurements and original silhouettes. Instinctle never asks that. Here the answers live on the canvas: a crossing, a length, a vanishing point, a moment, a shade of gray. The two games do not share a question bank.
A few things you might wonder
Is Instinctle the same as Perceptle or Freehand?
No. Instinctle is an independent daily perception game with five original tests, its own scoring, and its own visual style. It is not affiliated with, endorsed by, or a copy of Perceptle or Freehand.
How is my score calculated?
Each test scores 0–100 on a published curve with a small perfect-score window, then a smooth falloff. Pointing tests use a Gaussian on the distance to the true point. Stretch uses a log-ratio, so twice as long and half as long score the same (36). Between uses milliseconds, Aftertone uses lightness points. The constants are initial design values, labelled as such on the How to play page, and will be frozen after an internal playtest. Five tests make a total out of 500.
When does the daily puzzle change?
At midnight in the eastern United States (America/New_York), including daylight-saving changes. Unlimited practice is available at any time and does not change your daily score or streak. Replaying a past day from the archive also leaves today’s official score alone.
Do I need an account? Where is my streak kept?
No account is required. Your daily scores, streak, and best total are saved in this browser on this device. Clearing the site’s data will reset them. Switching devices will not carry them over.
Can I play Between with the sound off?
Yes. Between’s main cue is a pair of visual flashes. A short optional beep can sit on top, but the flashes, the interval, and the scoring are unchanged when the site is muted or the device is silent.
Is this a medical vision or hearing test?
No. Instinctle is a casual daily game about perceptual instinct. It is not a clinical test, a diagnosis, or a substitute for professional care.
