game consists of four identical pieces, clear plastic double cube, one with a small red ball in its center, one with a green ball. Each player gets 2 pieces. Players alternate placing pieces which must touch on at least one face, staying within a virtual 3 x 3 x 3 cube. Goal is to get three of your color in a row 3D tic tac toe style...

I don't remember the name of the game and I don't remember some of the rules.

Can anyone help?
