A game for the budding architect in your house. This one player game includes 18 building blocks of various shapes and sizes and a picture book of 3D structures. The object of the game is to build the 50 structures in the book, which increase in difficulty as you go along. Although the first few structures are easy to build, the more advanced structures are extremely challenging and even adults may be unable to complete them. Luckily, answers are provided for each model in the back of the book. Children and adults with an interest and ability for this type of applied thinking enjoy this challenging game.
