Guess the Number play online

The player decides to guess one of the numbers from three to six. According to the number of numbers decided by the player, the APP will randomly set a group of non-repeating numbers as the bottom of the puzzle, and the player will slide the number wheel to guess each number in the middle column. Each time a number is guessed, the APP will give a hint according to the number in the display area below, and the hint will be presented in the form of X+Y-. X means the number of correct numbers and positions, while Y means the number of correct numbers and incorrect positions.
For example, when a player guesses a four-digit number, when the answer is 1234 and the player guesses 1052, the number 1 is the correct number and position, while the number 2 is the correct number but not the correct position, so the APP will prompt 1+1-.
