Handball has traditionally used 2 points for a win, 1 for a draw and 0 for a loss, and most club leagues still do. Some tables show points as a pair — points won and points lost, such as 18:6 — which is the same information as a win-draw-loss record written another way.
Games are high scoring, with each side regularly reaching the twenties or thirties, so goal difference is the natural first tiebreaker and spreads out quickly. Beach handball is scored differently, by sets, and is usually run as its own competition.
