Actually, it depends on each player's preferences, but yes, a higher RTP for a beginner is better. For that purpose, I won't talk about specific online slots, but I believe I can help you find the right ones by following these simple tips:
Check the RTP: Well, it's a basic rule, slots with a higher RTP generally offer better long-term winning potential. I personally prefer games with RTPs of +95%.
Volatility: From my perspective, smaller wins with less risk are better for beginners and it's a good responsible gambling practice. So make sure to choose the one according to your risk preference.
Bonus Features: Slots with bonus features like free spins, multipliers, or bonus rounds can provide more opportunities to win. You know, it's up to you to find the right platform that responds to your expectations.
This is just my point of view, and I believe there are members on this forum who are more experienced than me and can add more details regarding this matter
I think that live RTP is very beneficial for gamblers. There are two ways to risk, you either choose a game with high RTP with the expectation that you'll drain it till the RTP is high or you choose a game with low RTP with the hope that it's the lowest right now and the RTP will increase significantly as you gamble.
