Poker is the game with both the best and worst odds in a casino. It has the best odds because it is the only game in which you can have an edge. You are not playing against the house, but rather against the other players (with the house just taking a cut of your winnings). If you are significantly better than the other players, then poker is profitable. However, for this exact same reason, it also has the worst odds because if you are worse than the other players, you are losing twice: once to the players, and again to the casino!If you are struggling to win at poker, then you need to improve your game. One of the best ways to do this is by studying. Read some poker books, read poker strategy articles, and invest in an online poker course. Review your sessions and look for mistakes. Mistakes you regularly make are called "leaks". Common leaks for players include playing too many hands (especially out of position), bluffing too much (or not enough), and chasing draws with bad odds.Probably the biggest reason that poker is so hard (especially online) is that there is an abundance of information available to help players improve. You need to take advantage of this information or you are putting yourself at a severe disadvantage to those who are!
