Krillion Science and Nature Practice

Unlimited rounds on one subject. Elements, units, planets and animals. Original prompts by Krillion Today, not the official Krillion.

Science and Nature: seven prompts, 25 seconds each

  • Type one answer that fits the prompt. The less common it is, the more it scores.
  • If we don't recognise an answer, keep trying until the clock runs out. It only costs you time.
  • The clock keeps running if you switch tabs.

What you'll be asked

Each round draws 7 of the 9 science and nature prompts in our practice bank, with 25 seconds for each. These are all of them; the answers stay hidden until you play.
