I recommend a game called Balatro, which is available on various platforms. I've recently become obsessed with this roguelike game. At first, I thought it was similar to Texas Hold'em, but it actually has little to do with it; it just uses the Texas card types. Based on the card types, it provides base chips and multipliers, calculates the chips for each card, and then triggers the effects of all played xxxxx cards, with a maximum of 5 cards played at a time.
I've been playing for 2 days straight and still haven't fully grasped the strategies. I only managed to clear a level once with a brainless flush. For beginners, I recommend the flush as it has a high clearance rate. If you fail, you can just play another round; each game is a completely new start, with different jokers and card decks. Every choice is crucial, and before you know it, several hours have passed.
I'm also studying and learning, and I encourage everyone to come and play; it's not a scam!
