10Below: Daily Trivia

A new dive every day. Ten questions, thirty seconds each. How deep can you go?

Ten questions. One dive. 10,000 m to the seabed.

Every day there is a new dive of ten questions, with thirty seconds for each. Your answers take your submarine down:

• Rare answers: name something in the category. The rarer your answer, the deeper you go. • Estimates: guess the number. The closer you are, the deeper you go. • True or false: call it right and drop 500 m.

Think your answer should count? Appeal it, and get a ruling straight away.

See how you rank against every diver today, start a league with friends and family, race a friend head to head, keep your daily streak going, and take on The Depths when one dive a day is not enough.

No sign-up: open it and dive.
