How public rooms work
A room is a live lobby where up to 8 players take on the same colors at the same time. The host picks one of the game modes — anything from the classic memory rounds to Imposter, Speed, or Flags — and everyone gets the exact same sequence of target colors, in the same order. Because the puzzle is shared, the scores line up cleanly: you’re all guessing the identical swatch, so the gap between your reveal and everyone else’s is a fair read on who saw the color more accurately.
Nothing about a room is stored on your device beyond the nickname you pick, and that only lasts for the browser session. The lobby you see above updates every few seconds by polling the room registry, so a room somebody opens on the other side of the world shows up here shortly after they create it. When a room fills to 8 players the Join button locks and it drops off the joinable list until a seat opens.
Public vs private rooms
Rooms listed on this page are public: anyone browsing the lobby can join until the room is full. If you’d rather play only with people you invite, create a private room from the home page instead. A private room works the same way but never appears on this list — you share the six-letter room code, or send the room link directly, and only people with that code can find their way in. Public rooms are the quicker way to get a full table with strangers; private rooms are better for a set group who want to run several matches back to back.
Creating and hosting a room
Pick a nickname, then either join an open room from the list or hit create to open your own. As the host you choose which mode the room plays, and you control when the match starts, so latecomers can still slot in during the countdown before the first round. If you’ve only played on your own so far, it’s worth running a few solo rounds first to learn how a mode behaves before you host strangers in it. There are no accounts and nothing to install.
Reading the reveal
The part that makes rooms different from playing alone is the reveal between rounds, where every player’s guess is stacked next to the true color at once. Seeing six attempts at the same swatch side by side is a fast way to calibrate your own eye — you notice that the guess you were sure about actually leaned too warm, or that someone else consistently reads lightness better than you do. Over a few rounds you start correcting for your own bias instead of guessing blind, which is the same skill the eye-training drills are built around.
Fair play
Everyone in a room sees the same targets, so there’s no hidden advantage to being host or joining early. Nicknames are checked before they’re saved, and anything obviously offensive is rejected. A monitor calibrated way off — extreme brightness or a heavy color filter — will skew your guesses more than any trick would, so if your scores feel off across every mode, check your display settings before blaming the room.
How room scores are worked out
Each round is scored on its own mode’s rules, then those round results are what you compare across the room. For the color memory modes, the distance between your guess and the target is measured with CIEDE2000, a formula tuned to match how far apart two colors actually look to the human eye rather than how far apart their raw numbers are — a difference the maths would treat as large can look tiny, and CIEDE2000 corrects for that. Land dead on the target and you take the round; the closer the whole room clusters, the more the small perceptual gaps decide the winner. Room results feed the same global tally as solo play, so a strong showing here still counts toward your country on the country leaderboard. If you want the exact formula, the CIEDE2000 explainer walks through it.
