If you have an account on only one online betting site, then place a regular reasonable bet. You can see from the examples on this page that it is challenging to win with risk-free bet offers. Therefore, your task is to find good odds and hope to win.But there is a clever strategy to use for risk-free bets: matched betting. Create two accounts, allowing you to make a risk-free bet on both online betting sites and bet on opposite outcomes. For example, Total Over at the first bookmaker is 2.5, and lay odds on Total Under is 2.5 at the second one. You're sure to win in one case, and in the second case, you receive insurance if a risk-free bet loses. Bookmakers don't like clients who practice these risk-free betting strategies, but all the rules are formally followed.
