Zer0s © 1973 People's Computer Co.
A simple strategy puzzle game that's played against the computer and shares similarities with Nim. The playing field consists of 8 zeroes in a row. The spaces between them are numbered one through seven. The player and computer take turns picking a number and drawing a bridge. Adjacent bridges can't be drawn any more. When a player runs out of options that player has lost.
Released in February 1973.
