Explore space, chemistry, the human body and Earth science. Each round has seven open questions with 25 seconds to name one valid answer. An uncommon answer climbs higher.
Unlimited Climb · Science
7 prompts · 25s each · the rarer your answer, the higher you climb — from alpine meadow to the summit at 7,000 m.

Try an example
Name an element with atomic number 1 through 20. Oxygen fits and earns 10 points. Silicon also fits and earns 60. Iron is number 26, so you can try again while the clock is still running.
Each point adds 10 metres to your climb. Rarity tiers are set before play. See the full scoring rules.
Keep practicing
Choose Climb again at the end to stay in science. The 28-prompt pool gives you four rounds with no repeats in one session before the questions begin to cycle.
