Harrah's Rincon $$$ per point is $5 for 1 point, so 100,000 points requires $500,000 thru the machines; this would probably require a bankroll of around $50,000 figuring you will win $10 for every $1 you play and lose. I have won 125 points for a $20 play (a record for me) and Alice has won over 400 for a $100 play and got her money back, this is not a constant but just an idea of what could be.

Also, some points could be earned based on table play.
