Abstract: An educational and recreational game having a case-like rectangular basic structure including an outer support structure and an interior frame with interchangeable principal transparent playing elements and insertable underlying complementary transparent elements which upon insertion change the style of recreational play and introduce various mathematical relationships represented by lines on the elements into the game. The complementary elements or inserts singularly and collectively form a series of mathematical figures which are used in basic and advanced mathematics and are used in the game for instructional purposes. There are several circular openings in the principal playing surfaces with associated arch-shaped, cylindrical targets and stops located atop the principal playing surfaces. Structure is provided for retrieving the balls which roll upon the principal playing surface.
