Dots - duel

1. Take turns placing one dot on any free intersection.
2. Close a line of your dots around enemy dots to capture them.
3. Keep your own dots from being surrounded.
4. The game ends when the board is full or a player reaches the target number of captures.

Dots - duel is a two-player game of encirclement played on a grid. Blue and red take turns placing a single dot on an intersection, and once placed a dot never moves. When your dots form a closed line — horizontal, vertical or diagonal links all count — around some of your opponent's dots, those dots are captured. The player who captures more wins. Because every dot is permanent, each move has to do two jobs at once: tighten a net around the opponent while keeping your own groups from being boxed in. Choose a board from 10×10 up to 30×30, and play the computer, a friend on one device or an online opponent.
