Guess the Number

Hunt down a secret number before your tries run out. Each guess tells you higher or lower, plus a heat clue for how close you are.

Tries left10 / 10

I'm thinking of a number between 1 and 100. You have 10 tries — hunt it down!

Best (Medium): —Wins: —Optimal: 7

1Pick a difficulty: Easy (1–50, 8 tries), Medium (1–100, 10 tries) or Hard (1–500, 12 tries). Switching difficulty starts a fresh round.
2The game picks a secret number somewhere in that range. Type your guess into the box and press 'Guess' (or hit Enter).
3Every guess comes back as 'too low' or 'too high', plus a heat reading — from Freezing to Boiling — and a closeness bar showing how near you are.
4Under the input the game narrows the range the secret can still be in, tells you how many numbers are left, and points out the midpoint.
5Guesses must be whole numbers inside the range, and you can't repeat a number you have already tried.
6Land the secret number before your tries run out to win. Run out and the answer is revealed.
7Your best guess count for each difficulty and your total wins are saved in your browser; 'Reset stats' clears them.

Always guess the midpoint of the remaining range — that is a binary search, and it halves the possibilities every single time.
The 'Optimal' figure at the bottom is the fewest guesses a perfect binary search needs here; treat it as the score to beat.
Treat the heat clue as a sanity check only. The narrowed range and its midpoint are what actually guarantee the win.
