Kapla

Kapla is a construction set for children and adults. The set consists only of identical wood planks measuring 11.7 cm x 2.34 cm x 0.78 cm. This 15:3:1 ratio of length:width:thickness is better than more traditionally proportioned building blocks (such as unit blocks) at building features such as lintels, roofs and floors, and great stability can be achieved without the use of fastening devices.
