- Goal: Be the first to capture 3 of your opponent's tokens.
- Controls: Tap/click any empty cell to place your token.
- Capture rule: An opponent's token is captured (removed) when ALL its orthogonal neighbors (up/down/left/right) are occupied or off the board edge.
- Corner tokens only need 2 neighbors to be captured — very vulnerable!
- Edge tokens need 3 neighbors.
- Center tokens need all 4 neighbors — safest spots.
- Self-capture: If your newly placed token is itself surrounded, it's removed and counts as a capture for your opponent.
- Multi-capture: One placement can capture multiple opponent tokens at once.
- Win: First to 3 captures wins. If the board fills, the player with more captures wins. Equal captures = draw.
- Tip: Use board edges as free walls to trap opponents. Keep your tokens in the center with open escape routes.
