Playing at online sportsbooks, real money casinos, and sweepstakes sites should always be safe and enjoyable. Keep control of your activity by following responsible gambling guidelines such as:
Decide on a budget you’re comfortable with and stick to it. Once it’s gone, stop playing.
Trying to recover losses often leads to overspending.
Avoid playing under the influence, or when angry, stressed, or tired.
Take breaks and ensure gambling doesn’t cut into time with family or friends.
Learn the rules, bet types, odds, and payouts before playing to avoid mistakes.
Make use of features like budget limits and self-exclusion.
