Abstract
Toy blocks are usually design with target on kids. This research aims to design a toy blocks that can be enjoyed by families. The idea of toy blocks in to increase the variation of the way of stacking to make more challenging for playing. This is a proposal of toy blocks focused on center of balance and surface of material. Balance of center was changed by using the weight and surface of material focused on frictional force of material. By the prototype of toy blocks, increasing the variation of stacking ways have been confirmed.
In the final production, experiments for university students were carried out.The result of text mining analysis shows the possibility of toy blocks for adult.
