Guess the Number

Find the secret number from 1 to 100 with as few hints as possible.

1. Find the secret number between 1 and 100 in as few guesses as you can.
2. Type a number and press Guess or Enter. After each try you'll see Too high or Too low, so you know which way to go.
3. A game has 5 rounds, each with a new number and no limit on guesses. At the end you'll see how many tries each round took and your average.
4. Start at 50 and keep cutting the remaining range in half: that way you'll always find it in 7 guesses or fewer.
