Gaining a facility with spatial relationships is fundamental to understanding higher math. Crystal Draughts and Time Vectors require spatial-relational cognition on a more elementary level, and the GRYB Game System on a more intensive level.
Other topics to explore are quaternary tree data structure (GRYB), multi-dimensional coordinate system (Time Vectors), concept of integration (all games), game invention (all games), strategic-thinking skills, instruction set-following skills, and concentration skills. Games are also useful in building social skills.
One goal of JDB Games is to see implementation of these games in educational applications.
On the Blog, you can place comments concerning educational uses for these games or other games with educational value.
