There is a saying. House always wins! If you are an old gambler, you may know about this. New Gamblers may get surprised about seeing this and may say, well, I am still in profit. I would say, Go on, buddy. We will meet again in the future.
Yeah, Most of the old gambler on play games like Blackjack and Poker to have a better chance of winning with playing the basic strategy. Some still playing slots but they are just doing it to hunt high multiplier using fixed bankroll unlike newbie that will chase jackpot without considering the total expenses of the bankroll. I’m not a regular player of slot games but playing it longer will make user just loss since it house 5% average house edge which is very high for a game that being played for long game session.
Beginners always counting just their current profit and forget what’s the real deal of gambling in long run. In result, they are always the users here that blaming or creating scam accusation against casino in retaliation with their losses.
Blackjack do also has a lower house edge than the rest of the games while I don't know if how much is the house edge on poker but if you are a skillful poker player, you have a good chance of beating the house. These two games are still best if played in offline especially poker because there are methods in poker which only works IRL. Hunting high multiplier and hunting for the jackpot are seem close enough.
Both are still painful in the pocket. As for me, I only play slots when I want to chill but if I want to be serious and possibly want to earn a profit, I will play strategic games like black jack and poker. Blaming casino for your own loss is too funny but may be some will believe on it if the casino is guilty that there are manipulations that happened.
