I don't bet so I have never gotten the highest...
I think you should try betting yourself so you can share based on actual experience. It’s different when you just watch or read about it compared to when you’re the one gambling, the feeling is completely different.
Also, max wins in slots aren’t based on how much you bet. Whether your bet is big or small, if you’re really lucky, you can hit the max win as determined by the slot game’s mechanics. And if you ever experience hitting a max win, screenshot it, develop into picture and frame it as that’s a huge achievement for any gambler!
