I was the sent the latest 3D puzzle from Ravensburger recently and with 4th July just around the corner I had fun building it. Ravensburger do a range of 3D puzzles that use plastic pieces that interlock to make all different shapes including famous iconic buildings.
This great puzzle features 108 high quality plastic pieces and measures 37.5cm tall when complete. Each puzzle piece is printed with a number on the reverse side, so you can either assemble the puzzle by eye, or just by following the numbers, which was my method. It also includes a printed base board, so it can be displayed on a shelf or table top.
I've personally constructed other 3D Puzzles from Ravensburger and this set is quite easy and quick to do and would make a great introduction to the range.
