Perceptle is a game, not the word perceptible

Wiktionary defines perceptible as an adjective: able to be perceived, sensed, or discerned. The Latin root it cites is perceptibilis, from percipere. That is a normal dictionary entry, and it is older than the browser game. Perceptle is the name on perceptle.com, a set of five timed perception tests with a score out of 100. The spellings share a prefix and then diverge.

I hit this when a search box quietly corrected the game’s name into the adjective. The results that followed were definitions, not a puzzle. If you can see Count, Track, Angle, Tempo, and Split, you are in the game, and the spelling with the final “le” is the one the site uses. If you are writing an essay, you want perceptible, and this page will not help you decline it.

A horizontal line with a mark just left of center — Split asks for a fraction along a line, measured from the named end.

Is Perceptle a word in the dictionary?

The game’s name is a coined spelling. The established adjective is perceptible. They are easy to confuse and they do not share a page of rules.

What does the game test?

Counting dots, predicting a landing, setting an angle, keeping a tempo, and marking a fraction. The name is a nod to perception. The rules are the five tests, not the dictionary sense.
