Make it easy to help by posting intact code and explaining what's stopping you from moving on/what information you want

#3

File "python", line 42
elif board[guess_row][guess_col] == 'X':
^
SyntaxError: invalid syntax

#4

Probably something wrong above that line.
Running what you posted will not produce that error message though, you must take care to show exactly what you're dealing with.

Oops, try again. Your code looks a bit off. Check the Hint if you need help! Your code threw the following error: invalid syntax (python, line 42)

File "python", line 42
elif board[guess_row][guess_col] == 'X':
^
SyntaxError: invalid syntax
