Krillion Depth Zones: The Ocean Map of Your Dive

What are the depth zones in Krillion?

The game’s scoring map doubles as a tour of the real ocean. As your answers sink you deeper, the screen scrolls past genuine milestones — here is every marker on the ruler, top to bottom, exactly as the game presents them.

The sunlight zone (0–200m)

This is where every dive starts. The ruler’s first markers: “light begins to fade” and “most sunlight stops here” — then the deepest scuba dive ever, 332m. Sperm whales hunt below this line, and emperor penguins dive this deep.

The twilight markers (200–1,000m)

Pressure climbs to 67× the surface. The siphonophore drift zone passes by — then THE MIDNIGHT ZONE begins: anglerfish territory, where sperm whales duel giant squid, colossal squid with football-sized eyes, and water that is 2°C and utterly black.

The abyssal zone (1,000–4,000m)

THE ABYSSAL ZONE: the Titanic rests here at 3,800m, cusk eels patrol the plain, and it is deeper than most submarines survive. The abyssal plain stretches out beneath your dive.

The hadal zone (the trench)

THE HADAL ZONE — “named for Hades. fitting.” — ends at the trench floor, where the ruler’s final line sits: “a perfect dive ends here”. Since depth is score ×10, a perfect seven One-in-a-Krillion answers (700 points) lands you at 7,000m, on the floor.

Why the map matters for your score

The zones are more than scenery: they give you a feel for how deep each tier sinks you — a Deep Cut (+85, 850m) takes you past the scuba record into sperm-whale territory, while stacking Rare answers (60 each) marches you through the Midnight Zone toward the bearing bands.
