Can You Guess a Random Number in 20* Guesses?

* Or 10 Guesses, if you're feeling lucky.

How to Play:

  1. Set the high number for a 1 - XXX range in the box to your left.
  2. Click "Generate Random Number!"
  3. Try to guess the random number. You have 20* guesses to get it right, with high-low hints offered after each guess.

* Optional: Hard Mode

If you want a little more challenge, set Hard Mode. This mode reduces your number of guesses to 10.

For the biggest challenge, choose Hide Previous Guesses as well. This mode doesn't tell you what previous guesses you've made.

Enter the maximum number for the random number range.
