About Cosmillion Online

Cosmillion Online is a small, independent fan site for Cosmillion, the daily word game where the rarest answer wins. We are not the makers of Cosmillion and have no link to them; the official game is at cosmillion.com. Here you can play our free Daily Chart and Cosmillion Unlimited practice, read Cosmillion answers today and the archive, and learn the game from our guides, starting with what is Cosmillion.

Our own game

Our game code, star-chart art and star names are our own. The Daily Chart uses our original bank of 410 prompts across 47 topics with 93,078 accepted answers. Its tiers are editorial estimates, not a survey. Unlimited also offers 420 official prompts from cosmillion.com, with 129,018 accepted answers and the published aliases, score tiers and rarest-answer notes. Choose Official, Original or Both before starting a chart. Official practice may reveal answers to daily launches; it does not follow their daily order.

How the answer pages are made

Each official launch gets its own page, 21 so far. After a launch opens at midnight India time, we read the official board for each prompt and publish a short selection: the One in a Galaxy answers, samples of Deep Space and Astronaut answers, and the most common answers, with counts per rank. Each page shows when it was last checked. We never publish a launch before it opens.

Corrections

If our game rejected a fair answer, a tier looks wrong, or an answer page does not match the official game, email hello@cosmillion.online with the prompt and the answer. We fix confirmed errors the same day and note the change on the page.
