Slitherlink (Unequal Lengths) (871)

Instruction:
Draw a single, non-intersecting loop that only consists of line segments between the dots along the dotted lines. A number inside a cell indicates how many of the edges of that cell are part of the loop.
The loop goes straight through a different number of dots (possibly zero) before and after each turn of the loop. (In other words, if you write down the distance between two consecutive turns of the loop in the order in which you go around the loop, you will never write down two of the same number in a row.)
