The Game
What Is Ninestone?
A modern abstract strategy game built on a classic formula — refined for quick, tense, deeply satisfying play.
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 unfolds in two distinct phases: a strategic Placement Phase where pieces are placed, followed by an intense Movement Phase where pieces slide into position.
The Flying Rule
When you're cornered with only 3 pieces left, despair becomes speed — you may move to any empty node on the board. Fight back from the brink.
Victory Condition
Reduce your opponent below three pieces — or leave them with no legal moves — and the game is yours. Every capture counts.
Play vs AI or a Friend
Challenge the computer bot or pass and play with a friend on the same device. Ninestone II variant adds diagonal connections for even deeper strategy.
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 so they have no legal move. The board belongs to you.
