Eye of Horus
Two expansions have been released for the game. The Eye of Horus beam splitter expansion adds a new piece that is similar to a Djed, but which splits the beam. When a beam strikes the beam splitter, half bounces off at a right angle, as with the other mirrored pieces, while the other half continues on directly through the mirror, thus creating two beams out of one and adding a new strategic element to the game. Eye of Horus beam splitters are available in gold and silver, for those who own the old Deflexion game, and in red and silver, for those who own the newer Khet game. With the expansion pack, each player receives one beam splitter, which replaces one of their Djeds.
