The player views the entire board from above. A turn consists of selecting one ball and moving it to an empty square, provided a clear path exists between the two positions.

After a move, new balls are added to the board. Completing a line of the required length removes those balls and awards points; multiple lines or favorable arrangements can make a single move especially valuable. The game continues until no legal move remains or the board is full, with the score serving as the main progression measure.

Plan routes before moving a ball, because a destination that is technically open may block a more useful path on the next turn.

• Preserve central and connecting squares when possible.
• Build potential lines without filling every useful empty space.
• Prefer moves that create more than one possible line or clear the board immediately.
• Watch the preview of incoming colors and avoid leaving isolated balls that cannot contribute to a line.
