Our experts test every site we review thoroughly, including checking the software providers. While every game has a different return-to-player ratio, all games at reputable, regulated, and licensed online casinos offer a fair chance of winning.  Several factors contribute to this. Firstly, the penalties for any casino found to be rigging games are incredibly severe. And, even if the penalties weren’t harsh, news spreads quickly online, resulting in an unscrupulous casino finding itself without players. Many online operators use random number generators to ensure fairness, and some even implement blockchain technology so that all games are “provably fair”.
