Hello Loza!
It was really smart for you to use String and its length to check the numbers.
I just wanted to let you know that you could be using less "for" at the end. You skip every 3 steps, therefore instead using i++ or j++ you could be using i += 3 and j +=3, and then adding an inside "for" to loop through the numbers. Not sure if this will help but remember that in a "for" it is not necessary to implement a n++ at the end, you can implement anything you want.

Good point Dario! Didn't really think about it, thanks!:*

Hello Oscar!
Whenever you create an int[] in java it will set every value as 0. In this case, once you have set int[][] board, it will be already filled with 0s.
I hope it helps!

PS: Loved the way you coded "play" with all functions, really easy to read

Should return [10, 49] as the 10 first positions are correct but from the 10th to the 49th are not, well [0, 49] was expected.
