Well, just because it happened in one type of game doesn't mean it will happen again, it's a mistake to think that, as it might as well happen in another. It's unlikely because it's a very big stroke of luck but it doesn't depend on a certain game.
i'm well aware of that, i'm not new to this.
but i also like to believe that you are always one spin away from a big win, hehehe.
I would bet that it is one with high volatility though.
or a medium one, a 3354x payout is well within the max win of most of hacksaw medium volatility slots.
If you are playing slots an alarm clock is your best friend.
Set for 1 hour and stop when the hour is over.
i do something similar, but instead of playing for a set amount of time, i go with a set budget.
