First off, look for places that are licensed and regulated. That's like having a bouncer at the door checking IDs. It means they're playing by the rules and keeping things on the level.
Payment options are crucial too. Reputable casinos offer a variety of methods, from plastic to e-wallets. Stick with the big names and you're less likely to get burned.
Fair play is non-negotiable. Random Number Generators make sure the house isn't stacking the deck against you. It's like the online version of shuffling a deck of cards.
I've been doing some digging into online casinos lately and stumbled upon this site called The Mulligans. Seems like they're ticking all the boxes for security and they've got a solid lineup of games too. Check 'em out if you're still on the hunt: https://themulligans.org/
