The dive
Seven prompts. One descent.
The rare-answer game, rebuilt as a full-screen 3D dive. The obvious answer barely moves the sub; the answer nobody else reaches takes it to the trench floor.
One answer, one descent
Correct answers sink the sub by their rarity. Plankton moves 40m; One in a Krillion moves 1,000m. Press NEXT after every result.
Seven prompts, 7,000m
String together rare answers across all seven prompts and reach the trench floor. No accounts, no daily wall, no download.

Questions
Before you dive.
What is Krillion?+
Krillion is a free browser dive about giving the rarest correct answer. You get seven open prompts, twenty-five seconds each, and one typed answer per prompt. The deeper the sub goes, the higher the score.
How does scoring work?+
Every accepted answer has a rarity tier. Plankton answers move you 40 metres; One in a Krillion answers move you 1,000 metres. A perfect seven-prompt dive reaches the 7,000 metre trench floor.
What happens when I answer wrong?+
A wrong answer ends the prompt with no distance. The answer card shows NO CATCH / OUT OF AIR, then you press NEXT to start the next prompt. A timeout works the same way.
How do I advance to the next prompt?+
Every prompt has one answer. After you submit, the sub dives if the answer is accepted, and a feedback card appears. Press NEXT to deal the next prompt. There is no auto-advance, so you can read the result.
Is this Krillion 3D?+
Yes. This is the Guessingame 3D conversion: a procedurally modelled research sub, surface boat, island, depth gauge and animated ocean. The source Krillion page is a pixel side-view game.
Can I play Krillion multiplayer?+
Not in this build. The original supports live rooms with up to 40 players. This version is a single-player dive against the clock; live multiplayer needs a realtime server and accounts.
Is Krillion free?+
Yes. The dive is free in your browser with no account and no download.
Can I play Krillion unlimited?+
Yes. There is no daily lock on Guessingame’s Krillion. Finish a dive, then press Dive again for another round with a new seed.
Where can I play Krillion online?+
Play at https://guessingame.org/krillion. The game runs in the browser on this page.
Does the game save my progress?+
No. Every dive starts fresh. There is no account or server-side profile in this 3D build.
