honestly, if you rarely play slots, you better keep it that way. but here is my suggestion anyway, maybe try some medium volatility hacksaw games:
https://betfury.com/casino/providers/hacksaw-gamingone of my fav atm is ze zeus and klowns, and if you are feeling risky you could play one of their high volatily game like wanted (i would not recommend that).
I tried the zeus game. At first, i went below my starting balance, but after some free spins, I got lucky, recovered about $9, made a $2 profit and stopped playing. I found it fun and also plan to play BetFury's original games.
The adrenaline of seeing your balance drop is on another level, but recovering everything feels really satisfying. The important thing is to have fun and be aware that you can win or lose. Most importantly, only play what you're willing to lose.
