When I visited Arogsy and the Grand Vicotira last week, they are both now electronic, NO COINS what so ever. Everything is based on dollars and credits. They do this because when people play slots
for change and win their change is dropped on the bottom, so say you take $100 in quarters and win a few here and there, your not going to take your change out of the bottom untill your out of quarters, and by then you will be ahead. So when its all said and done you walk away a winner.
Now if your playing and you have no change at the bottom, but you have the credits in the machine, your going to keep playing until you win more.
Its more of a physiological thing if you ask me. I know when I was ahead I told myself to cash out and take my ticket to the cashier, but I ended up staying and losing what I won! If I had the change at the bottom, I would have stopped once the change in my hand ran out!
