Mayan, Pantasia...
Not only do they pay up, but seems there's always another bonus and even the odd No Deposit $25 freebie waiting in your mail box.
I was lucky just once - 1st time winner,
since then haven't cracked it at either venue.
And their games can be a bit tedious.
Can't stand the Islots thingys -
with their "now downloading file 3 of 15" - then the silly lil games you are forced to play, like taking a date to a movie, or trying to putt golf balls around various obstacles or whatever...

Think I'd prefer the reels to keep spinnin, mate!
but have no fear about collecting your winnings.
The 5 days might stretch to 8 when there's a weekend in between, but I have found them both most accomodating and pleasant to deal with.
