Goukaku Boy Series - Shikakui Atama o Marukusuru - Zukei no Tatsujin — About this game
Solve Japanese geometry questions with attention to flat figures and solid shapes. Read the diagram together with the question: the position of a line, a hidden face or the way a shape is viewed can change what is being asked. Choose an answer only after comparing the possibilities, then use the response to reconsider the drawing. A short set of problems offers a way to practise visual reasoning without rushing past the details that distinguish similar-looking figures.
