Ninestone & Ninestone 2

Ninestone is a two-player abstract strategy game played on a board of three concentric squares — an outer, middle, and inner ring — connected by spokes at the four cardinal points. The board has 24 intersections, called nodes or junctions, where pieces can be placed and moved.

Each player controls 9 pieces (stones) — one player plays Black, the other White. The objective is straightforward: reduce your opponent to fewer than 3 pieces, or leave them with no legal move.
