Tivia Plays Intersphere
Intersphere was founded by Peter Marshall and Andrew Riddell and the company that manufactured this system operated from 1993-2012. The phaser is uniquely ergonomic and two styles of packs were manufactured. The X packs were made in Iowa with U.S. corporate headquarters in Des Moines and the O packs were made in Holland.
I XOXO Playing Intersphere!
There are very few places where Intersphere can still be played. There is no question it is a rarity to come across. It may have been associated with the name Laser X, which coordinates with the X pack design. I have been fortunate enough to get to play using both the X and O packs.
