Once I used the play 200 points, get a free buffet coupon at Gold Coast from ACG to experiment with super duper low slot grinding strategies. I would insert $1 in a minimum bet 9cent (with all lines played) and play for as long as it lasted. Then I would insert the next dollar...and so on like that. It took me $15 risked with that strategy ultimately to reach that 200 points (1:1) and I was still up a $1 in the end. I would say I played for 2 hours and they were fair slot machines (several tiny wins like 30 cents but nothing major). How do you play when you do a super duper low slot grind? What would you say is your average coin-in when you grind like this, and with how much risked?
