The Game
What Is Ninestone?
A two-player strategy game built on a classic formula: simple rules, real depth, and matches that rarely run long.
Three Rings, 24 Nodes
The board features three concentric squares — an outer, middle, and inner ring — connected by spokes. Every node is a battlefield.
Form a Rail™
Align three of your pieces in a row along any ring edge or spoke to form a Rail™. When you do, you earn the right to remove one of your opponent's pieces.
Two Phases of Play
The game has two phases: a Placement Phase, where you place your pieces, and a Movement Phase, where you slide them into position.
The Flying Rule
Down to your last 3 pieces, you can move to any empty node on the board instead of just an adjacent one — a last chance to turn the game around.
Victory Condition
Reduce your opponent below three pieces, or leave them with no legal moves, and you win.
Play vs AI or a Friend
Play against the bot, or pass and play with a friend on the same device. Try the Ninestone II variant for diagonal connections and extra Rail™ paths.
Get Started
How to Play in 60 Seconds
Players take turns placing one piece on any empty junction. Each player places all 9 stones before movement begins.
Any time you complete three pieces in a straight line — along a ring edge or a spoke — you've formed a Rail™ and must remove one enemy piece.
Once all pieces are placed, slide your stones one space along any connected line each turn. Keep reforming Rails™ to eliminate pieces.
Reduce your opponent to fewer than 3 pieces, or trap them with no legal move, and the game is yours.
