Unlimited practice
Seven random archived prompts per run. Play as many seven-question sets as you want, with each dive scored out of 700. Your current progress and result log stay in this browser.
Official Daily Dive

How scoring works
Accepted answers descend by rarity.
Every answer in the archive carries a reveal tier. Your seven-round score can reach 700 points, and each point takes you 10 metres deeper, up to 7,000 metres. Scores use the archived tiers, rather than a live count of players’ answers.
Midwater
Schooler and Rare answers balance safety with enough specificity to leave the crowd.
Trench
Deep Cut and One in a Krillion answers sit at the far edge of the accepted list.

FAQ
Free unlimited Krillion questions
Can I play Krillion unlimited for free?
Yes. This independent practice mode serves seven random prompts from the public answer archive with no payment or account. Finish a dive and start another set whenever you want.
What is infinite Krillion?
Infinite Krillion and unlimited Krillion mean practice without the one-dive-per-day limit. Each practice dive here contains seven random questions. Finish with a score out of 700, then begin a fresh set.
How does the free unlimited game score answers?
Your answer is checked against the archived accepted-answer list for that prompt. The six reveal tiers award 10, 15, 30, 60, 85 or 100 points. Each point is 10 metres of depth, up to 700 points and 7,000 metres per dive.
Does unlimited change today’s Daily Dive?
No. This practice score stays in your browser and does not submit anything to the official Daily Dive. The official daily result remains separate at krillion.io.
Is this the official Krillion unlimited game?
No. Krillion Game is an independent companion using dated public reveal data. The live official game and validator remain at krillion.io.
Why was my answer not accepted?
This game checks answers against the archived accepted list for that question. A valid answer outside that list may not be recognized. You can try another answer before the 25-second timer runs out.
Can I skip a question or resume a dive?
You can skip for zero points. An unfinished dive is saved in this browser for up to 12 hours, but its current timer keeps running while you are away or refreshing.
