CISRA Puzzle Competition 2011 - Solutions

5A. Latin Pipes II

Shown below is Andrew Shellshear's worked solution, with numbers annotating the order in which the squares are solved. The order isn't canonical – at many points there are several possible squares to solve. There is only one particular bit of logic in this version – for square 43 (top row near middle), the top of the square has to be a pipe otherwise the "·" and "–" pieces cannot be placed.

Once all the squares are solved, we look at the intersection dots. Colour in all the sections that contain a dot, and you get the shape below.

The shape represents a RABBIT, or BUNNY, either of which is acceptable as the solution. LAPIN is also accepted (due to the connection with the puzzle title), though we definitely missed a trick by not thinking of LEPUS.
