How Depth Drill works

One answer, 25 secondsEach round deals five prompts — name a country, a US state, a capital. Type one answer before the clock drains. No hints, no take-backs.

Rarity is depthEvery valid answer has a rarity tier: Surface answers score +10, Shallow +30, Midwater +60, Deep +85, Abyss +100. Depth is score — 100 points sinks 1,000 meters.

Daily is shared, endless is yoursThe daily dive deals the same five prompts to everyone, once per pack per day. Endless mode shuffles the whole bank without repeats, as long as you want to dig.

Judging you can trustAnswers are judged against a fixed word list with common aliases — no AI, no hunches. If it is on the list, it counts; if it is not, it does not. Same list, every player, every day.

Frequently asked

Is Depth Drill really free?

Yes — every mode, every pack, no account, no paywall, no ads during play. It is our own game and our own prompt bank, and it stays free.

Is this the same as Krillion Unlimited?

No. Krillion Unlimited is a paid product by Krillion's creators on krillion.io. Depth Drill is our independent take on the same genre — the rarest-valid-answer scoring idea is a shared game mechanic, but our prompts, judging, themes and scoring tiers are original. We are not affiliated with Krillion or krillion.io.

Can I practice more than once a day?

Yes — that is what Endless mode is for. The daily dive is once per pack per day (everyone gets the same five prompts); Endless deals new rounds without repeating prompts until the bank is exhausted.

What if my correct answer is judged wrong?

Judging is a fixed word list with common aliases, so borderline spellings (Côte d'Ivoire, Guinea-Bissau, UK vs United Kingdom) are covered. The full list ships with each pack and a validation script guards it — the same answer always gets the same verdict.
