That is, they design games that might look like they have a good probability to win for the gambler, but in reality, if you actually do the math, are very bad, and the odds are much better for the casino.
You are absolutely right, I personally cannot deny that in my early days as a player I always tried many casinos and supposedly only looked for the one with the best chance of winning , I had that mentality and when I searched on the internet for casinos with the highest probability of winning, the ones mentioned the opposite happened, they were the ones with the greatest chance of losing money faster, everything is done based on the casino always winning, and that is something that must be accepted.
