You have a set number of guesses to guess the ordered 4-fruit code. To select a fruit, click a fruit from the bottom of the screen.
Once you select the 4 fruits for a guess, hit the "Guess" button, and a "hit" and "blow" value will be displayed for that guess.
A "hit" means that one of the fruits you guessed is correct, and is in the correct place.
A "blow" means that one of the fruits you guessed is correct, but is NOT in the correct place.
Use the hit/blow values of your guesses to figure out the code.
You can change the number of guesses and the fruits from the options screen. Good Luck!
