UKGC-licensed casinos are legally required to have their Random Number Generators (RNGs) and payouts tested by third-party labs. Look for logos like eCOGRA, GLI (Gaming Laboratories International), or iTech Labs in the footer of the casino's website. They often publish monthly certificates showing the actual payout percentage.

Companies like NetEnt or Playtech set a "theoretical RTP" for their games. We compare the versions of the games the casino chooses to host (since some games allow the casino to choose between 94% and 96%) to determine the site's overall quality. If you want the absolute best payout, ignore the "site average" and look for specific games. For example, Blackjack played with a perfect strategy has a payout of 99.5%, while some Progressive Jackpot Slots (like Mega Moolah) can have an RTP as low as 88% because a portion of your bet goes toward the massive jackpot. Pub Casino is the best paying online casino with an impressive average return to player (RTP) of 98.26 per cent across its game library. We try options like PayPal, cards, and e-wallets, timing exactly how fast funds hit your account.
