Once, I tried to catch the jackpot for fun. I chose the minimum bet size(2 sats) and won a small prize, only 10k sats. It's worth noting that I didn't use any strategies but just set the auto-bet option and hoped for luck. Overall, I think I got lucky that time, as it took me only ~2,5k tries to see the cherished 8888 on the screen. Of course, if I had known when I would get lucky, it would have made sense to use max bet to get 1 BTC in that case.
