Five colors. Same for everyone on Earth. You get one shot. No pressure.
The Daily challenge gives everyone the same puzzle. One run, once per day, against the same five colours that every other player is seeing that day. The targets are generated from the calendar date in UTC and passed through a fixed seeded generator, so the set is decided by the date alone and not by when you happen to open the page. A 42 posted in London and a 42 posted in Tokyo came from an identical set of colours, in identical order, which is what makes the daily scoreboard worth comparing at all.
The format is the same as Solo on the easy setting: each colour flashes on screen for four seconds, then disappears and you rebuild it from memory with the hue, saturation and brightness sliders. There are no decoy swatches to rule out and no multiple-choice shortcut. You get one shot at each of the five colours, and the run you post is the run that counts.
When the page loads it reads the current UTC date and feeds that string into a deterministic generator. Same date in, same five colours out, for everyone. The order is fixed too, so round three today is the same swatch for you as it is for a player on the other side of the world. Nothing about the set is random at play time; the only variable is how well you hold each colour in your head after it vanishes.
The puzzle rolls over at midnight UTC. Depending on your time zone that might land in your morning, afternoon or the middle of the night, so the clock you should watch is UTC, not your local one. Come back after the reset and there’s a fresh set of five waiting. Playing on consecutive UTC days builds a streak; skip a day and the count starts over, which is the usual reason a streak breaks for players who assumed the day turned over at local midnight. The one exception: if you’ve reserved a free account, a banked streak freeze covers a single missed day automatically instead of letting the count reset.
In Solo you can play as many runs as you like and each one draws a brand-new random set, which makes it the right place to warm up or grind technique. Daily hands the same fixed set to the whole field and limits you to a single posted entry, so it rewards being calibrated before you start rather than after your third attempt. Treat Solo as practice and Daily as the graded run.
The most common self-inflicted wound is opening Daily cold and burning round one before your eye has adjusted. Play a couple of Solo rounds first, then come to Daily as a deliberate sitting. During the four-second view, name the colour to yourself in rough terms first (“muted teal, fairly dark”), then set hue before you touch saturation or brightness. Getting the hue family right is what saves a round from a low score. If you want to work on that recall specifically, the guide on training your eye for colour and the write-up on how colour memory works both cover the underlying skill.
Every one of the five colours is compared against your slider result with CIEDE2000, a perceptual distance measure that weights the gap the way an eye would rather than counting raw RGB numbers. A near-perfect match on a colour earns close to the round maximum and the points fall off as the distance grows, so a run of five decent-but-not-exact guesses can still total well. Your five round scores are summed into the daily figure that gets posted. Because the set is shared, that total is directly rankable against everyone else who played the same date. The leaderboard has a Daily view for today’s top runs, and you can read the full how to play rundown if you’re new to the sliders.
