Just back from EW and thought you may be interested:
3 match payout, up to 125 coins, for four 7s
1 100 free slot club points
1 free buffet
2 2X points
3 for cash, $5, $5, $20, $5
and plenty for t-shirts or hats.
This was out of 25 envelopes, so there were plenty that we don't even
recall.
Believe the Treasure Chest in the hosts is filled from the Treasure
Chest next to Slot club.
