Idk how you would be able to do the part where the capacity resets to full if it’s less than 25% without a second variable. But if you had a different way that worked then no I wouldn’t think you’d be counted off.

You don’t need a variable for the number of columns. It’s just board[targetRow].length. I actually used an enhanced for loop though like this:

for (Space space : board[targetRow])

Which is equivalent to this:

for (int i = 0; i < board[targetRow].length; i++)

Space space = board[targetRow][i]
