What games should I focus on as a complete beginner?

Just started playing sweeps casinos this week and honestly feeling a bit lost with all the game options. I've been bouncing around between different games trying to figure out what actually clicks for me, but I'm wondering if there's a smarter way to approach this.

I've got some sweeps coins to work with from my first deposit, but I don't want to burn through them without a plan. Are there certain games that are better for newer players to understand the mechanics? Or games that just feel more rewarding when you're starting out?

I read a bit about volatility and RTPs but that's still pretty abstract to me. Looking for real talk from people who've been playing longer - what would you recommend focusing on first? Should I stick with one game to learn it well, or is it fine to sample a bunch of different ones?

Also curious if anyone has thoughts on bankroll management when you're just getting your feet wet. I'm not planning to deposit huge amounts, but I want to make sure I'm not making rookie mistakes.

Thanks for any guidance. The community here seems pretty helpful based on what I've seen so far.
