Trimula appears to be an implementation of 3D Noughts and Crosses. It looks from the box that it was released sometime in the early 70s. The contents consists of a clear plastic 3D game board which can be assembled and disassembled at will, and a more than adequate number of large glass marbles in two colours. However whilst it is a game in a 3 x 3 x 3 matrix, it has very different win conditions to Tic Tac Toe in that the player with the most row of 3, when the pawns are all played, wins.
There are a number of other such games where the players use 3 boards arranged to yield 27 playing positions.
