Endless Descent

One prompt at a time, three air tanks. Misses cost a tank, an Abyss answer refills one. How deep before you run out?

How it works: one prompt at a time, with 3 air tanks. Type one answer and press Enter.

  • A wrong answer, an empty answer or a timeout costs a tank.
  • An Abyss answer refills one (max 3).
  • Run out of tanks and the descent ends. Prompts get harder the longer you last.

How Endless Descent works

Endless Descent drops the seven-prompt limit. You receive one prompt after another with the same 25-second timer, and you keep going until you run out of air.

Tips for staying alive

Unlike the seven-prompt dive, a safe answer is worth something here, because any valid answer protects your air. Early on, bank a quick Surface answer and move on. Save your creative guesses for prompts you are confident about, and try for the Abyss when you are down to one tank. See the full list of tips for finding rare answers.

The pool currently holds 149 prompts. A run never repeats a prompt, and prompts you saw recently are held back, so each descent feels fresh. Prefer a quick session? Head to the seven-prompt Unlimited Dive or pick a topic pack.
