Knowledge Showdown
Fifteen questions of rising difficulty about probability and how bookmakers make money. All the rules are set out here, before you start. Nothing changes halfway through.
The rules
- There is no timer. No countdown, no time bar, no limit of any kind. Take as long as you like.
- You can stop any time. The Stop & keep button sits between every question, the same size as Answer.
- A wrong answer does not wipe you out. The run ends, but you keep the tokens from the last milestone you passed.
- You cannot gamble your winnings. No double-or-nothing, no all-or-nothing, no putting banked tokens back at risk.
- Each lifeline can be used once per run.

There is no leaderboard
No comparison with other people, no streaks, no daily medals. The Showdown is here to teach, not to keep you here.
