Stragone

Stragone is a 1977 game by Jacques Le Floc'h, published by Polyajeu.

Each player has eleven light and eleven dark stackable pieces. 

BGG describes the following rules:

The goal of the game is to take or block the opponent's checkers. Each player's pawns are placed on the front rows. In his turn player moves his piece (pawn or stack). To move, a pawn jumps one hex or be stacked one ofof his pawn directly next hex. A stack of two pawns jumps 2 squares. A stack of three pawns jump 3 squares, etc. A piece by jumping over an opponent's piece "takes" and removes it from the game.

A translation from the website L’Escale à Jeux:

Goal of the Game: Capture or block the opponent's pieces.

How to Play: Each player's pieces are placed on their first rows. Players take turns moving one piece (a pawn or a stack).

• To move, a single pawn jumps one space along one of the three axes of the hexagon.
• A pawn can be stacked onto a directly adjacent piece. Another pawn can then be added to this stack, but a stack cannot be placed onto a single pawn.
• A stack of two pieces jumps two spaces.
• A stack of three pieces jumps three spaces, and so on.
• A piece jumping over an opponent's piece "captures" it: the top piece of the opponent's stack is removed.

Commentary: A piece—whether a single pawn or a stack—cannot reach all spaces; it moves along a specific network.

• For single pawns, there are four independent networks.
• For stacks of two, there are nine networks.
• For stacks of three, there are sixteen networks.

Mastering these movement mechanics is key to developing a winning strategy.
