How do I solve the ice tic-tac-toe puzzle?

I need help with the ice tic-tac-toe puzzle. If you may not know what I’m talking about, let me try to explain where it is; it’s after telling Papyrus what you did with his spaghetti and solving the puzzle after. Once you solve that puzzle after, there comes another tic-tac-toe obstacle on ice. How do I beat it?
