Eight rungs. One real body of knowledge. How high do you dare climb?

How to play knowledge climbs

  • Eight rungs, each a question with four answers. Every rung you clear grows the pot.
  • Walk away at any rung to bank the pot, or risk it for the next level.
  • Levels 3 and 6 are safe havens: clear them and that pot is yours even if you fall.
  • Use 50:50 once per climb to remove two wrong answers when the heat is on.
