From the Invisible City Productions website:A runaway maze game for two to four subatomic particles.Using deflector chits, energy tokens, and a six-sided die, each player attempts to guide their pawn through the board gathering electrons and depositing them in his collector. The first player to have three electrons in his collector wins -- not so easy, since the deflector chits can be changed by any player....All the pieces (except for the die and the energy tokens) plus the board and rules are available here: http://www.invisible-city.com/play/53/accelerator - BoardGameGeek
