Krillion Space is a free browser-based space trivia game in which players decode one daily transmission and then fly an endless voyage past real planets, nebulae and galaxies, one correct answer at a time.
What is Krillion Space?
Krillion Space is a daily space trivia game that runs entirely in a web browser on phones, tablets and computers with nothing to download. Each day it presents one timed puzzle (a "transmission") that every player in the world receives at the same moment, and it turns correct answers into forward movement for a ship travelling an endless route of real cosmic landmarks. Input is multiple-choice or typed answers; output is points, voyage depth, leaderboard position and a persistent route record. No account is needed to play as a guest.
What makes Krillion Space stand out?
- Rotating daily scoring — rarity days (Sunday, Monday, Wednesday, Friday) ask you to name an answer and pay 10 points for a common correct answer up to 100 for an exceptional one, while deduction days (Tuesday, Thursday, Saturday) give three tries worth 100, 60 or 30 points.
- Voyage mode — an endless run of multiple-choice nav checks along a route of 34 real landmarks from the Moon to the Andromeda Galaxy; a right answer warps the ship one stop deeper and a wrong one costs hull, with a breach drifting you back.
- Timed crises — some nav checks arrive under a countdown as a debris field, solar flare, gravity well, ion storm or comms blackout; beating one in time can yield salvaged plating, a slingshot past an extra stop or a storm-charged shield, while a slow or wrong answer hits harder than a normal miss.
- Ghost duels — five-question races against another pilot's recorded run, with a duel rating tracked for signed-in players.
- Crews of up to six — friends join under one name via an invite link, share a crew leaderboard, send each other enciphered transmissions to crack, and start colonies on uncharted worlds where the crew can dock and repair.
- Real spacecraft imagery — planets and moons use NASA, JPL and USGS maps, Saturn's rings come from Cassini, and nebulae and galaxies are Hubble, Spitzer and GALEX photographs, all itemised on the site's image credits page.
- Star Atlas and archive — the Atlas holds a fact sheet for each of the 34 real places on the route, and the archive keeps every past transmission available to read or replay.
- Five leaderboards — today, this week, deepest voyage, duel rating and crews.
Who should use Krillion Space?
- Daily-puzzle regulars: players who already keep a streak on a once-a-day word or number game get a second 00:00 UTC reset with a comparable streak to protect.
- Space and astronomy enthusiasts: people who can name Saturn's rings or the Orion Nebula get scored puzzles built from real NASA, JPL, USGS, Cassini, Hubble, Spitzer and GALEX imagery, plus a Star Atlas fact sheet per stop.
- Friend groups and small teams: up to six pilots can form a crew, share a leaderboard, trade ciphered messages and co-found colonies.
- Competitive trivia players: ghost duels and the deepest-voyage board give a repeatable score to chase rather than a single daily result.
What can you do with Krillion Space?
- Commuters with a few spare minutes: decode the day's transmission on a phone browser, keep the streak alive, then close the tab without installing anything.
- Trivia-minded friends: start a crew with an invite link, crack each other's enciphered transmissions and compare crew standings against other groups of up to six.
- Curious students: read the Star Atlas entry for a place such as the Moon or Andromeda, then fly the voyage to answer nav checks about it under crisis countdowns.
- Returning players: replay any missed transmission from the archive or study past answers before the next 00:00 UTC drop.
How does Krillion Space work?
- Open the site in a browser at krilion.app — no sign-up is required for a guest run.
- Decode the daily transmission: on rarity days type your answer and be scored on how rare your correct pick is among all players; on deduction days narrow the signal down within three tries.
- Switch to the voyage for endless nav checks, answering each to warp one stop deeper and managing hull against crises.
- Optionally sign in with an email code or a passkey to sync progress across devices, appear on leaderboards and access rated duels and crews.

FAQ
Do I need an account to play Krillion Space?
No. Anyone can play as a guest. Signing in with an email code or a passkey keeps progress on every device, places you on the leaderboards, and is required for rated duels and crews.
When does the new daily transmission appear?
A new transmission arrives every day at 00:00 UTC and is identical for every player worldwide, so answers can be compared. Missed days are recoverable because every past transmission stays in the archive.
Is there a Krillion Space app?
There is no app to download; the game runs in any phone, tablet or computer browser. On a phone you can add it to the home screen from the browser's share or menu button so it opens full screen.
Are the planets in the voyage real?
Yes. Planets and moons use real spacecraft maps from NASA, JPL and the USGS, Saturn's rings come from Cassini imagery, and nebulae and galaxies are Hubble, Spitzer and GALEX photographs, each listed on the image credits page.
