The object of this game is to grow your groups of pieces and surround and capture your opponent's groups. A group (or "body") is a set of your pieces that are connected by horizontal or vertical connections. A player's turn consists of two parts:
- First, the player selects one of her pieces, and moves it to a cell horizontally or vertically adjacent to a piece in the group to which the moving piece belongs. Normally the destination cell must be empty, but if an opponent's group is completely surrounded the destination cell can contain a piece of that opponent's group, in which case that opponent's piece is removed.
- Second, the player places a new piece adjacent to one of her existing pieces. (It doesn't have to be adjacent to the group that was used in the first part).
A player wins when her opponent cannot move, either due to having no pieces remaining or having all pieces surrounded.

Player 1 (red) can move the highlighted red piece to the highlighted cell diagonally down and left, and then add a new piece in the other highlighted cell. This will connect all red pieces in a single group which allows for more flexible movement, and keeps the two blue groups separated.
