About PlayVexle
A flag drawing game built around one question: can you actually draw the flag you think you know?
Recognising a flag is easy. Reproducing one from memory is a completely different skill, and the gap between the two is where this game lives. PlayVexle covers 194 national flags, with 115 side-by-side comparisons of the pairs people mix up.
How the scoring engine works
A naive pixel comparison would punish a good drawing for being a few pixels out, so the scorer does something closer to what a person does. Both images are normalised to the flag's official ratio, blurred, reduced to a small grid and converted to the CIE-LAB colour space. The flag's colour vocabulary is extracted from the artwork itself, then every cell of your drawing is matched to the closest of those colours.
Colour placement is 70% of the result, block layout 20%, and edges and emblems the last 10%. Positions are compared with roughly 5% of the flag width of tolerance in every direction, which is what lets an uneven but correct tricolour score in the nineties while a correct-looking but reordered one does not.
Flag artwork
The reference flags are SVGs from the open hampusborgos/country-flags collection, which renders flags largely from Wikimedia Commons sources. They are downloaded at build time and served from this site — nothing is hot-linked at runtime. Flag designs themselves are national symbols and are not owned by this project.
Colour codes, proportions, layouts, memory notes and the mistake lists in the flag guides were written for this site.
Privacy
There are no accounts and no server-side profiles. Your streak, best scores, per-flag records and today's drawing live in your browser's local storage and never leave the device. Clearing site data resets your history. No drawing you make is uploaded anywhere.
Independence
PlayVexle is an independent project. It is not affiliated with, endorsed by, or connected to any other flag game, site or organisation, and none of its code, artwork direction or written content is taken from one.
Corrections
Flags change, and reference sources disagree about exact shades. If something here is wrong — a colour code, a ratio, a claim about what a design means — it is worth fixing. The data lives in one structured table, so corrections are a one-line change.
