Quick Answer: Virtually every major team sport uses a coin flip at the start of a match to decide first possession, end choice, or serve order. It is the universally accepted neutral method for giving both sides an equal starting opportunity.
Why Sports Use Coin Flips
In competitive sports, the first choice of ends, possession, or serve often carries strategic advantage. A coin flip gives both teams an equal 50% chance of gaining that advantage — no skill, no negotiation, no bias. It is fast, universally understood, and accepted by all parties. No alternative method offers the same combination of speed, neutrality, and simplicity.

Cricket: Where the Coin Toss Has the Most Impact
In cricket, the coin toss is considered one of the most tactically significant moments of a Test match. Pitch conditions evolve dramatically over 5 days — batting conditions, pace, and spin all change. Captains who win the toss and read the pitch correctly gain a substantial advantage. Statistical studies suggest winning the toss provides between 5-15% increased win probability depending on pitch and conditions.
