Loop

You have to make lines between the black dots by clicking in between. Each dot can only have 2 lines coming out of it. Each line links to each other. The lines together form a single loop. The symbols represent how many lines are in the edges of the particular square(like minesweeper). The circle with dot means there is only one line in that square, Ankh means there are two lines in the square and Illuminati triangle means there are 3 lines in that square. A red line means you have made an error in the number of lines available from that spot.
