Kotlin: How do i implement the counter for my twodimensional array?

Question

Hey guys,
i was trying to make a TicTacToe as an exercise for Kotlin.
As you can see i'm pretty far at getting it to work.
My only problem is that i don't know how i implement the counter in the right way at line 80. If I add just the "i" the error says: "Type mismatch: inferred type is Array<Int> but Int was expected".
Do you have an idea how to fix that?
