PlayVexle

PlayVexle gives you no picture to copy. The daily challenge names a country, and you draw its flag on a blank canvas using brush, fill, rectangle, circle, line and star tools, with an eraser and undo. When you press Reveal and Score, your drawing is compared with the real flag, shown side by side with yours, and a difference overlay marks the parts you missed.

The score has three parts. Colour is 70 percent: each part of the flag is matched to the closest colour of the real one, so a slightly different blue is fine but blue where red belongs is not. Layout is 20 percent, with a little slack at the edges. Detail, the emblems, stars and crests, is only 10 percent on purpose, so the scoring is forgiving: a canvas filled with plain blue for Nauru, with no stripe or star, still scored 87 percent. Up to three outline hints trace the flag's shapes without showing colours; simple flags get fewer.

A new flag comes at midnight UTC, the same for everyone, and the schedule is set so that look-alike flags never fall on consecutive days. The daily Build puzzle, new at the same hour, is for players who know a flag but cannot draw it: pick a layout of two or three bands, then a colour for each, and the marks on each guess narrow it down over six tries.

Practice with any of 194 flags, an endless Infinite run, Memory Flash (see the flag for a moment, then draw it), a ten-question flag quiz and an archive of past dailies are there for more play, along with drawing guides for every flag and side-by-side pages for pairs people mix up. Progress and the streak stay in the browser with no account, and the site shows no ads. This is a separate game from Vexle at vexle.org, with its own daily flag, numbering, tools and scoring.
