Duonnect 4 is a two-player abstract board game that combines strategy and originality.

Duonnect 4 offers deep strategy with simple rules, requiring careful planning and prediction every turn. It introduces unique mechanics that set it apart from traditional "connect four" games.

How to Play

• On your turn, perform two actions in order:
◦ Place one of your own stones.
◦ Place one of your opponent’s stones.
• Stones must be placed in an empty cell adjacent (up, down, left, or right) to the last placed stone. This rule creates a dynamic where you both help and hinder your opponent each turn.

Win Condition

• Be the first to connect four of your own stones in a row—vertically, horizontally, or diagonally. Every match is a balance of offense and defense.

Key Features

• Local two-player mode on one device
• Single-player mode against AI
• Completely offline play
