VI 003 - 4/9 Connect

Connect these 9 dots using only four lines, and without lifting your pencil from the paper. (Hint: Think beyond real and imaginary boundaries with this puzzle.)

Answer Key

Start experimenting with lines that extend outside the square, and the answer comes quickly. Here is a solution: if the dots are numbered 1 through 9 from left to right, draw a line from dot 1 through 5 to 9, then up through 6 and 3 and outside of the box, then back down through 2 and 4, then right through 7 and 8. This will allow you to create other solutions based on these rules.
