My wife enjoys the slots as well, she has been playing on the blue one for a while and doesn't like the green and red ones, she likes to win even if small and just continue gambling instead of gambling and losing for a long time hoping you can hit big once.
I am exactly the contrary, I hate gambling for hours and have exactly zero to show for it, I may break even and that's fine but I just dislike the notion that I just spent hours and made zero, either Imma lose all my money in the end or Imma profit a ton with a big jackpot or some big win, that is when I feel like I am actually gambling. Otherwise whats the point if at the end I lost just couple thousand satoshi or won couple thousand satoshi, it is not never happened and doesn't matter, it is the big wins that matters to me.
