I don't play roulette and baccarat because I think those games have a highly volatile system. I did play Aviator/Crash before because it's up to you when you want to stop. The non-greedy ones can make some money there.
Plinko is one of the top games for me when it comes to casino games. I think the RTP is better there, and if you want to build some wagered amount, you can definitely create a big one there without spending way too much money. After that, I swing by to slots just to test my luck, but I won't play for too long.
