@dar2112vConsidering there is nothing besides credits for you to win the odds could be that the longer you play the more you'll win?
I hit 25 credits at least 6 times and small denomiations many more times. But there certainly weren't any particular "streaks of good luck" along the way so I can't speak to your question based on my experiences.
I didn't have any set limit but figured that 60 up, 100 scratchers and 1 hour was about right so left after that.
Due to my ability to only win credits I almost never play any of these games and normally when gambling I always end up losing so in this case I am happy with where I left off.
It's an hour that I didn't have anything better to do so I don't consider the time particularly *****. Clicking and swiping the mouse over the 'tickets' certainly isn't taxing physically so I don't consider it work in any way. And it is mildly entertaining from a suspense standpoint.
As to your other comment about the SEC's I am also personally not in favor of the company keeping some of their product mostly out of reach of their customers but unfortunately it seems to be continuing so Totem must be seeing a financial benefit or they would have quit long ago. I suspect that the silent masses who don't participate in this forum lean heavily towards supporting this scheme by continuing to buy the product and playing the games despite the sometime vociferous complaints seen here.
