Lines of Action (LOA) is an abstract strategy game that uses a checkerboard and pieces but with a completely different premise. The goal is simple: gather all your pieces into a single connected group, where each piece is adjacent to another, whether horizontally, vertically, or diagonally. It sounds easy, but every move requires careful planning, as you can also capture opponent’s pieces by moving in the same line. Created by Sid Sackson and published in his book 'A Gamut of Games,' LOA is a quick and engaging mental challenge for two players. With simple rules but strategic depth, it’s perfect for those who enjoy games that test anticipation and tactical skills.
