Lines of Action (or LOA) is an abstract strategy board game for two players invented by Claude Soucie.

[1] The object of the game is to bring all of one's pieces together into a contiguous body so that they are connected vertically, horizontally or diagonally (8-connectivity).

At his request, I have corrected an error in the rules for LINES OF ACTION, eliminating possible draws."

However, despite the intention of the inventor of LOA, most present day tournaments including the World Championships at the Mind Sports Olympiad score simultaneous connection as a draw.

The strategic depth of the game, however, derives to a large extent from blocking strategies designed to limit the opponent's mobility.

It can be advantageous to pin one or more enemy pieces against the side of board by moving in the second row or column.

White, despite the substantial disadvantage of moving second, apparently is in the lead now due to the reduced mobility of Black's first-row pieces.

White will soon play a2-d2, continuing to build his own bridge and forcing Black's piece on e1 to move sideways if it wants to join the game.

[2] A variant of Lines of Action with a different starting position was also proposed by Soucie and is known as Scrambled Eggs.
