This is a simple Knarly Works puzzle (size 4x4). To return to the Knarly Works page, click on the "End Animation" button. The animation will loop repeatedly, so don't worry if you miss something the first time through (or the 6th time...)

The puzzle "solving area" is the lower-right 2/3 of the game window below (greenish colored). To the left of it and above it are the clue tiles (purplish colored) containing pipe sections. This animation will use yellow boxes to highlight the clue tile that it is currently working with and the location on the puzzle where it is going to place the tile, or where it can NOT place the tile, depending upon the deduction. In this simple puzzle, MOST of the deductions will be "this is the only remaining place where this tile can be placed" (because it's the wrong shape for any other possible locations). The deductions being made are explained (very) briefly below the puzzle. Remember: tiles to the left of the puzzle must remain in their SAME row as they're placed into the puzzle, and tiles above the puzzle must remain in their same column!
