The game involves guessing a mysterious number using the fewest
possible attempts.
Choose a number from 1 to 25 and enter it in the empty field on the
left.
If the guessed number is too large or too small, a message will
appear instructing you to choose another number.
Upon correctly guessing the mysterious number, a winning message
will appear. If the result is the best so far, it will be recorded
in the "highscore" field.
