Diagonale

This is an Italian game by Gastone Fiori. Look like 3D Checkers with 3 transparent octagonal boards. Put one over the other like a tower. There are 3 kinds of pieces; a diagonal one, a concave one and a convex one (that perfectly fit the concave shape. The convex one appears like a little House You put 2 concave, 1 convex and four diagonal pieces on the line Cross.. All the piece can eat like Checkers in the same board.. but can eat in different mode on parallel board according with their shape. Convex and concave pieces may "Kill" pieces on other boards if they are in a "reflected diagonal" with an opponent piece.. diagonal pieces may kill pieces on other boards if they form a diagonal with the opponents piece.
