      How to Play — Number Up

      • You will play 10 rounds of number guessing.
      • Choose a level to set the number range:
        Level 1: 1–20 · Level 2: 1–100 · Level 3: −100–100
      • Each round starts at 10 points. Every incorrect action reduces the round score by 1.
      • Make a guess; I’ll answer “higher”, “lower”, or “yes”.
      • Once per round you may ask: “Is it even?” using the button.
      • The number line shows what’s still possible based on your guesses and parity info.
      • If the number isn’t found in 10 steps, the round score is 0. Total is the sum of all rounds.
