Use the roundel to randomly identify tools the players may add to their player boards (toolbox) to complete the pattern consisting of tiles of tools.

First one to collect all the tools, and having placed them in the right order, wins. If all tools have been properly placed, the players have also made a picture of Bob and his friends. Turn the toolbox upside down and see if all the tiles were correctly placed.

The Swedish game name "Byggare Bob - Samla verktygen" directly translates to "Bob the Builder - collect the tools" in English.
