Ladder 818

The challenge: place vertical "chutes/ladders" to create paths which will connect the circles on the left with the same colored circles on the right. The circles on the left may only go to the right, up, or down (left is not allowed) as they follow the paths you create for them. If a circle's path comes across a vertical "chute/ladder", the circle must either go up the ladder or down the chute (going straight past one is not allowed). The number of columns of check boxes tells you how many "chutes/ladders" you must place (one per column). After there are no more check boxes to check, slide the "done" slider down to see if all of the paths are correct (the word correct will appear). If the word correct does not appear, uncheck the necessary check boxes, and try again. There are 120 different puzzles (actually, there are only 119, one of the puzzles requires zero "chutes/ladders").
