Quite a drive from Chicago area (figure 5 - 7 hours), but this is the
closest regional group to post this info to.
Database currently claims:
"North Star: The same 25c bonus poker (6-5 bonus with five separate
progressives) as Onieda. Other 97%+ Play are 25c 7-5 white Hot Aces
and on multi-denominational Austin Powers they had 8-5 "Mini Me"
jacks for quarters. Cashback is 0.2%."
I can confirm cashback is .2%.
I couldn't find the 6/5 bonus poker progressives. I believe they're
gone.
They give BOTH husband and wife $10 for your anniversary month. It
was our anniversary so a nice $20 to kick things off! Nothing
mentioned or in print about birthdays.
Casino has Blackjack ($3 - $25 tables), 3 card poker ($5), Let It
Ride ($5), and Craps ($5) available now. Blackjack was decent. 2
deck and 6 deck games. Double Any 2 cards, Resplit aces (except 2
deck), Double After Split, Dealer hits soft 17, and attention
blackjack lovers...they still pay 3:2 on your blackjacks in
Bowler!!! (Nearest airport is Central WI Airport...I know you're all
salivating 
I checked several machines in the casino, but I never did check the
banks of White Hot Aces. I assumed they'd be the same as the WHA at
the bar (6-5). They were always full and I didn't want to hover over
anyone while they played as I wrote down the paytable.
I didn't even consider looking at Austin Powers machines. I assumed
they were just slots and the wife gets bored when I "walk all over
the casino looking to make an extra .000078 percent. Sheesh!"
What I did find....
Bar plays: 93.78% Joker Poker, 94.82% Deuces, 7-5 (96.6%) WHA, and a
one eyed jacks game I can't find a paytable for, however it's
definitely lower than 94%. All of these at quarter level.
Some Game King Multi-game, Multi-Denoms had the same or worse (nickel
payoffs were worse, no VP in dollars on these.)
Interesting Find...
There is a bank of 4 Game Maker uprights on a wall near an entrance
about the middle of the casino (sorry I don't know if it was North
wall or what...the casino isn't that big you'll find them). They are
dollar machines that only take 1 or 2 credit bets. Each machine has
it's own progressive meter for the royal. With a 2 credit bet 2
machines paytables are
Royal (I assume starts about $1200 since 2 machines were around $1250
and the meters looked pretty slow - about a penny per bet)
239
65
16
10
8

I tried using Frugal to compute the return and came up with about
99.25% on these machines (at reset). I think that's a little low
since I tried to compute these playing one coin and couldn't cut 65
or 239 exactly in half. I rounded down to 32 and 119 respectively.
I used $1200 (600 credits) for the royal.
Machines 3 and 4 were standard 9/6 JOB, but note the progressive
starting at only $1200 for 2 coins in gave me 99.09% return from
Frugal.
If anyone out there cares to recompute please do. If you can tell me
where the progressive needs to be for break even I'd appreciate it.
All in all, not a lot of reason to go there unless you're in the area
for some reason and just want to play for fun. Or you're driving by
on your anniversary month. Quick $20!
