Part of the fun of the game up there is to try to figure it out yourself. If this is overly frustrating, or you just don't want to. Roll your mouse down a couple lines.
The goal is to build a pipe inbetween the two arrows. After you hit start, red will start moving from left to right between the arrows.
You can drag the boxes to the left of the left-most arrow into the section between the two arrows.
You can drop the box you are dragging on a box you have already dropped, as long as the red hasn't reached it yet.
When you drop a box, a new one will appear where you picked it up from.
I used to call my blog "Maybe if this title is witty enough...". It was a reference to an xkcd comic. When I moved over to my own host, I decided it was time for a name change.
