To check if a site is licensed, scroll to the bottom of its homepage — most legit casinos clearly display their licensing info there. Look for authorities like MGA, UKGC, or Curacao. You can also verify the license number on the regulator's official site. A trustworthy platform like Leon Casino always lists its credentials openly, giving you peace of mind that you're playing on a properly regulated site. Stay cautious of any site that hides or fakes this info.
