Physical casino slot games are worst. It has a low RTP compared to the slot games online. It’s RTP is low because casino needs to cover with all the expenses on their operations unlike online slot games that doesn’t have much cost to run it.
Physical slot games is just being audited physically so you can assure that everything is fair.
But with low RTP I think it’s very hard to win on that slot machines.
That's not accurate. Physical slots (like the online ones) have different RTPs depending on their provider, on their chain/ lines, if they are connected to a multiple-in-one jackpot, etc. Some get "updates" (meaning changing their RTP and payout system) every month, others every week. So, we can't know with certainty that their RTP is lower than that of online slots.
What is your thoughts.. do you think both are the same or physical casinos are more transparent than the online casinos? Let discussion wisely.
Honestly, I don't know, and IMO nobody can say for sure. However, I guess that it's easier to "fix" something online than something that needs physical presence.
