researching the highest payout online casinos 2026 for a group trip, any advice?

hey everyone. i'm helping plan a trip for summer 2026 and a few of us got talking about playing some games online beforehand. one friend is really focused on finding places with the best odds, arguing we should only play where the payouts are fair. i've started looking into it, but terms like rtp and house edge are kind of confusing, and every site seems to claim they have the best rates.

i'm trying to figure out what the highest payout online casinos 2026 might actually look like. not just who slaps a high number on their slot game, but which sites are transparent about their overall return rates and have that verified. what should we be looking for to identify a casino with genuinely better payouts? is it more about the specific game developers they host, whether they publish audit certificates, or their reputation among players?

any insight from people who pay close attention to payout percentages would be a huge help. we're just looking for a fair place for some casual fun before the trip, not to get ripped off by terrible odds.
