The 30-second version
Krillion is a browser game at krillion.io. Every day at 04:00 UTC, every player worldwide gets the same seven open-ended prompts. You type an answer for each — the game scores it by how rare it is among all accepted answers, not just whether it's correct. A common answer scores 10 points; an almost-nobody-else answer scores 100.
How scoring works
| Tier | Points | What it means |
|---|---|---|
| Plankton | 10 | The obvious answer everyone types |
| Too Clever | 15 | Accepted but the crowd got there too |
| Schooler | 30 | Middle ground — common but safe |
| Rare | 60 | Better than the crowd |
| Deep Cut | 85 | Specific and still valid |
| One in a Krillion | 100 | Almost nobody else typed it |
One point = ten metres of depth. A perfect 700 = 7,000 metres. Full scoring math →
