OVERLOAD -------- IT’S NOT OFTEN you come across a genuinely new stategy game, but Overload by Jason Butler of Holmes Chapel, Cheshire, is one such. In this two-player game, each player places counters On the board. When four counters of the same colour are piled together, they explode, scattering to surrounding squares. When the board gets full, chain reactions are set off as more and more squares overload in succession, like an abstract nuclear reaction. The game runs on the 48K Spectrum.
