Reply To: A 2-player game you can play with pieces you probably already have

Here’s another game:

Lines of Action (designed by Claude Soucie, first published in 1969 in the book A Gamut of Games)

You will need: A standard checkers set.

Setup: Place the 12 pieces of one color on the left and right side spaces (except the corners)
and the 12 pieces of the other color on the front and back sides (except the corners).

Gameplay:
The object of the game is to get all of your (remaining) pieces to be connected in a single group,
orthogonally and/or diagonally. (This includes having only 1 piece remaining.)
The players alternate turns (choose a first player by any method).

On their turn, a player moves 1 of their pieces.
A piece can move in any of the 8 orthogonal or diagonal directions.
The number of spaces a piece can move is determined by the number of pieces that player has
along the line of the board it is moving on. For example, if a player wished to move his piece to the left,
and there were another 2 of his pieces present on that horizontal line, his piece would be able to move
up to 3 spaces to the left. If he had no other pieces directly above or below a piece, and wanted to move
it up or down, it could only move 1 space (the total number of his pieces on that line).

A piece can be moved past (but not onto) a player’s other pieces, but not past the opponent’s pieces.
Pieces can move onto an opponent’s piece – if one does so, the opponent’s piece is removed from the game. (Be aware that this means the opponent now has fewer pieces that they must connect in order to win.)

(Note: If a player connects all of their pieces with a move that also reduces their
opponent to 1 piece, the player with more pieces remaining on the board wins.)
