Block by Block expands players' problem-solving skills as they combine seven puzzle pieces to construct up to 60 three-dimensional structures depicted on the challenge cards. The puzzle pieces are the same as the famous Soma Cube, which was a craze in the 1970's. This spatial puzzle is hard, and it's also very clever.
