Bulls and Cows

Four different numbers (from 0 to 9) are conceived. You have 10 attempts to guess all the numbers and their location. An attempt is a 4—digit number with non-repeating digits. In response, you will be shown the number of guessed digits standing in their places (the number of bulls) and the number of guessed digits standing out of place (the number of cows). Example: A secret number is conceived: "3219". Attempt: "2310". Result: one "bull" (one digit "1" is guessed up to the position) and two "cows" (two digits: "2" and "3" are guessed, but in the wrong positions). - To select a number, click on the "Sticker" and select the number you think is necessary (You can scroll or scroll through the numbers). Then click on the "Check" button. - By guessing the numbers, you increase your level and get stars. Stars can be spent on hints and additional attempts. But remember, the fewer attempts you use, the better!
