Question 1

What is Silhouette?

Accepted Answer

A free outline-recognition streak game. The screen shows a single black silhouette · your job is to pick what it depicts from a multiple-choice list. One wrong answer ends the streak. The catalogue ships 100 famous animals, foods, vehicles, places, and objects, each rendered as a Twemoji with the colour stripped away.

Question 2

How are the silhouettes made?

Accepted Answer

Every silhouette is a Twemoji vector drawing with the CSS brightness filter set to zero. That collapses every visible RGB pixel to solid black while preserving the alpha channel · so the outline stays smooth and the background stays transparent. Twemoji is the same emoji set Twitter shipped publicly · the rendering is identical across iOS, Android, Windows, and the web, so two players never disagree on what the silhouette looked like.

Question 3

How are the distractors chosen?

Accepted Answer

At low difficulty the distractors are pulled from any of the seven categories · the silhouette alone typically gives the answer away. At higher difficulty the distractors come from the SAME category as the correct answer, so a giraffe silhouette sits next to other animals and the player has to know what a giraffe outline actually looks like.

Question 4

Which categories are in the catalogue?

Accepted Answer

Animals (45 entries · dog, cat, lion, tiger, horse, zebra, deer, giraffe, elephant, dragon, unicorn, octopus, butterfly, dolphin, …). Nature (10 · trees, cactus, mushroom, sunflower, maple leaf, crescent moon, umbrella, …). Food (15 · apple, banana, pizza, hot dog, doughnut, croissant, …). Vehicles (15 · car, bus, motorcycle, helicopter, airplane, rocket, sailboat, …). Places (5 · Statue of Liberty, Moai, Tokyo Tower, Mount Fuji, castle). Objects (10 · key, camera, hammer, scissors, anchor, crown, …). Pick a category from the idle screen to focus on one bucket, or leave it on All for the full mix.

Question 5

Does it work in my language?

Accepted Answer

Yes. The UI is translated into all 25 PlayMemorize languages, and the 100 subject names reuse the localised emoji-name corpus that already powers Memory, Polyglot, and Ghost · so a Japanese player sees a Japanese "ライオン" and a Korean player sees "사자". No language is left behind.

Question 6

Why no faces, flags, or simple symbols?

Accepted Answer

Silhouettes only work when the source image has a distinctive outline. Faces and smileys collapse to a featureless circle once the colour is removed; flags become a flat rectangle; geometric symbols (squares, hearts, diamonds) are too generic. The 100 chosen subjects all keep a recognisable silhouette · animals with distinctive head/leg shapes, vehicles with distinctive proportions, named landmarks with iconic outlines, and objects (key, anchor, hammer) whose silhouette is the whole point.

Question 7

How does my progress save?

Accepted Answer

Best streaks are saved locally in your browser per (difficulty, choices, category) combination so different settings track different high scores.

Question 8

Can I play offline?

Accepted Answer

Yes. PlayMemorize is a Progressive Web App and Silhouette is part of the offline pre-cache. Once loaded, every round generates locally · no network needed, the Twemoji SVGs are bundled.
