How to play Slitherlink
Connect the dots with horizontal and vertical segments to form a single continuous loop that never crosses or branches. Each numbered cell tells you exactly how many of its four sides the loop must use; empty cells can have any number. Use those clues to deduce the one valid loop, as fast as you can.
