The offers for August from Harrah's Rincon Casino in San Diego County are coming in. There is a new twist on an offer for each Sunday in August: the more Sundays you show up, the more the offers increase.

There are four Sundays in August. The first Sunday I show up I get $180 of free play. The second Sunday I show up the free play increases to $235. It's $270 if I show up for three Sundays, and if I get there for all four Sundays the fourth Sunday is worth $360 of free play.

I'm not sure what my weekly money for August will be yet, but I expect it will be about $140, so if I combine the Sunday plays with the weekly free play, my Sundays look like this:

First Sunday $320
Second Sunday $375
Third Sunday $410
Fourth Sunday $500

I can increase the free play on any of those Sundays if I also use the bounce back free play that will come on August 1st. I don't know how much that will be.

And I can increase the free play on Sundays again by converting Total Rewards comp dollars to free play at the rate of $125 of comp dollars for $100 of free play.

Also in August, the Monday mystery prizes are back. Insert your card in a machine and you win one of six prizes:

$300, $400 or $500 of free play, or 35,000 or 45,000 or 55,000 of Reward Credits.

I'm curious to see what other offers come in for August.
