Digi-Guess: A number guessing

Want to exercise your brain? Want to sharpen your logical thinking? Try this simple game!
In Digi-Guess, you guess the number, but with a twist.
For each guess, the app will tell you how many digits are correct, and how many digits are also in the right position.
Try to beat your high scores and find your limit. Can you achieve a 2-digit number in 20 seconds? a 5-digit number in 2 minutes?
Have fun!
