How to bet responsibly in Colorado

Although knowing your sports helps, betting is primarily luck-based, so use these top tips to practice responsible gambling when placing a bet:

• Limits: Legal online sportsbooks allow you to set betting limits, i.e. limit how much you can bet in a day, a week, or a month.

• Cashouts: You can withdraw your winnings quite easily from any secure bookmaker, which prevents you from spending all of your winnings.

• Help & Resources: Regulated betting sites provide access to resources for problem gamblers and point them to organizations that can help with gambling addiction.

To help with gambling, we created a 'How To Bet On Sports' guide, that helps new sports bettors understand the industry better, to play safer and more securely.
