Rules, lifelines & scoring

Questions have a 20-second answer clock; the final question has 30 seconds. There is no pause.

Use each lifeline once: 50/50 removes two wrong answers; Ask the Hosts removes one. Only one lifeline per question.

Safe earns 100 points without a loss. Bold risks 250 points and needs a 250-point balance. All In doubles or loses your balance and needs more than 250 points. The final wager uses 50-point steps.
