Well I really like slot games especially when I just want to have fun and doesn't goal for profit. They are one of the best stress reliever for me, coming from work and wants to fill my tired body for having fun but it is more fun with the real slots, when I don't have choice but wanted to play, I'll just turning on my computer and play online.
If you want to have fun while gambling, you should play poker, as in my opinion, poker is much more fun than to hope that 4 same symbols will show up in same line. In real life casino, maybe it is better, but online i think that even dice roll games are better, unless you like fancy animations of all these spins, but i still think that playing poker with small bets and friends are best way to have fun while gambling.
Slot games are an alternative to sedative mind when we engage many defeats at the poker tables etc. It's a very good thing because we can still try luck even if you're trying to calm down, variation in slot game is often what I call passion enhancer machine.
