I am a Research Associate at the University of New Brunswick, Canada. I am testing the effectiveness of an on-line program that users can see the probable playing costs based on their playing style.  Players can vary: 1) how many days a week they play; 2) how many hours a day they play; 3) how fast do they play (how many spins a minute); and last but not least, 4) how much is usually bet on each spin. It is proposed that while sometimes a player can take home some big winnings, in the long run, the player is losing money. In the end, the more one plays the more one loses. I am testing is the RTP101 Program. This program is on the website http://www.rtp101.org. 300 participants in this study have a free chance in a draw for 6 cash prizes. Grand prize is for $500, the other 5 prizes are for $50 each.
