Answer 1

that will let me enter numbers and will only stop if it encounters 3 even numbers in a loop?

Sure just use int.TryParse and the remainder operator

The premise is value % 2 == 0 will be true when even

var evenCount = 0;
while (evenCount < 3)
{
   Console.Write("Enter a number : ");
   if (int.TryParse(Console.ReadLine(), out var value) && value % 2 == 0)
      evenCount += 1;
}
Console.WriteLine("game over...");

Output

Enter a number : 1
Enter a number : 2
Enter a number : 3
Enter a number : 4
Enter a number : 5
Enter a number : 6
game over...
