How to play Guess Number Up/Down

  1. The page opens in Practice: a fresh random number from 1 to 100 every round — play as many times as you like.
  2. Below the description, use the 📅 Daily Challenge / Practice toggle — Daily is the day’s shared UTC puzzle (everyone gets the same number until the next midnight). Switch back to Practice anytime.
  3. Daily allows up to 7 guesses per day. Solve within 7, give up, or miss on the 7th guess — then wait until tomorrow. Mid-round progress is restored if you leave and come back.
  4. Open Stats in the header (next to the title) for Daily and Practice tabs. Daily shows history plus current and best streaks. Practice shows games played, wins, average attempts, and best score.
  5. Type a number into the field and press Enter or the Guess button.
  6. Read the hint: Up means the secret is higher than your guess, Down means it is lower.
  7. Check the Previous guesses strip to see every guess so far with ▲ or ▼ for the direction.
  8. Halve the remaining range each time to close in, and enter the number exactly to win.

Practice scoring: score = max(0, 100 − (attempts − 1) × 10). Naming the number on your first guess scores 100, each further guess costs 10 points, and 11 guesses or more scores 0. Entries outside 1–100 are rejected and never count as attempts, and giving up reveals the number with no score at all. Practice tracks a best score. Daily challenge has no score — solve in as few guesses as you can within 7 attempts per UTC day. Stats records each finished daily (attempts and streaks) and tracks current and best streaks; the Practice tab shows aggregate games played, wins, average attempts, and best score.
