Double or bank. One miss burns the pot.
The Ladder is a nerve game wearing a quiz's clothes. Every correct answer doubles the XP pot — 1, 2, 4, 8, 16, 32 — and at every rung you get the same choice: take what you have, or push. One wrong swipe burns whatever you did not bank. It takes about a minute, and most of that minute goes on deciding whether to be greedy.
Swipe yes or no on a question about a market that already settled.
Correct, and the pot doubles. Now choose: bank it, or climb.
Wrong, and the unbanked pot burns. There is a new ladder tomorrow.
