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.
this is why i love medium volatility slots. they don't just take take take... you win some you lose some, and if you are lucky, you may end up in profit, but not much.
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.
just don't get addcited on the adrenaline, hehehe.
i would say knowing when to stop like you did is just as important too, $2 profit is better than chasing bigger wins and ending up with $0.
