ダイヤモンドゲーム

The star-shaped board has 121 spaces. Each player places 10 pieces (marbles or pegs) in one of the six triangle points. For 2 players, use opposite triangles. For 3 players, use alternating triangles.

The first player to occupy all 10 spaces of the opposite triangle with their pieces wins. All 10 pieces must be in the destination triangle.

Players take turns moving one piece per turn. A piece can move to an adjacent empty space (one step in any direction). Alternatively, a piece can jump over an adjacent piece (yours or opponent's) to the empty space beyond.

Build 'ladders' - chains of pieces that allow long multiple-jump sequences. Leave pieces behind for others to jump off - it helps your trailing pieces catch up. Block your opponent's jumping opportunities when possible.

2-player: Use opposite triangles for a head-to-head race. 3-player: Use alternating triangles, diagonal from each other. 6-player: All triangles occupied for maximum chaos and strategic blocking.
