My wife and I stayed one night in the hotel and WISH WE HADN'T. First let me say that both my wife and I are reformed smokers. The staff at the hotel was very gracious and professional. The room was very nice and well kept.

The Casino was wonderful, small, quiet and friendly. The problem was with the ventilation system in the hotel - it simply didn't work correctly. The smell of cigarette smoke was so bad, it was difficult to breathe at times. Clothes still packed in the suitcase smelled of cigarette smoke after only a couple of hours.

We had a no smoking room but may as well have had a tent over the room, with all the smokers in the casino exhaling into that tent!! I woke up at 1:00 a.m.; sinus' bleeding, dry raspy throat and would have left except, where are you going to go at 1 a.m.? We were 2.5 hours from home. We toughed it out, ate breakfast (which was very good) and left. Unless you REALLY enjoy smelling like a stale pack of pre-smoked cigarettes, I would recommend finding a hotel room elsewhere, enjoy the casino, then leave!

Nice place. I'm glad that they expanded the casino rather than taking the profit and running. I've noticed other casinos that haven't put a dime back into it.

There is a lot of room to roam around without running into someone when you are trying to get to a machine. I like the new reel em in games they have. A few more would be nice.

I like how I get money back to play on my players card. Last time I received 2 coupons for $25 each for free play. Last time I was at Mystique I got $1 and at Waterloo I got nothing.

The $5 buffet they have on Thursdays is the best value I've seen at a casino in several years. They could probably use a few more beverage servers but I like how they have self serve stations.

I noticed they rearranged the newer side of the casino which seemed to spread out the crowd on busy days. I wouldn't mind seeing their prize bank come back.

I've been to many casinos in Iowa and I can't say the Diamond Joes machines are any tighter or looser than normal. I gamble to have something to do and I see it as a source of entertainment rather than a money making affair. I'll go back there again.

The rating on this casino is low overall for a reason. I frequented this casino since the day it opened. When they first opened the machines weren't too bad, on par with other casinos. As soon as they did their expansion and hotel it went down the tubes. And now that they are in court facing a lawsuit from the Rock Gone Wild mess.... well when you see payout claims on their boards of 91.3% you can bet that whoever is in charge of posting has been soaking at the big wheel bar... 19.3% maybe.... and that's being generous! Rumor has it they have failed many past audits on payouts.

I have gone home ahead 2 times since they opened their doors, and went at least 2-3 times per month since opening day. Last time I was there I snapped my players club card in half and handed it to the worker at the counter on the way out the door. NEVER will I set foot in the dump again, I would rather drive an extra hour to a casino in Minnesota.

I live in waterloo and have been to the isle several times. Believe me, its worth the 90 minute drive to go elsewhere, slots are so tight. Hundred dollars gone in thirty minutes with nothing, the average pay back on quarters is, eight quarters, (if your lucky.)

Buffet is terrible always cold and food has been sitting awhile. If you want to gamble any length of time, I recomend to go elsewhere.

Have been here over 30 times, with and with out our tour group. This is just about as nice a place as you are going to find. Nice people, good food and a hotel as good as you will find anywhere.

There are many $1 machine that have very good paybacks. Have won many jackpots here by just playing $1 at a time. % Dosn’t go up by you playing and extra $. Stay away from machine that pay back 84 to 86% like the multi coin 1 and 2 cent machines. This only reason they are there is to make you poorer! Again this and the new Jumers in Rock Island make the others look sick.

The Monday special at the buffet rocked! Special was served, not a buffet, but lots of food and great value for the price! You just can't get a steak that good for eleven bucks! Service was great, folks were really helpful but sometimes didn't seem to know all details about their own promo.

Slots pretty comparable to casinos I've been to, really nice variety and some I haven't seen! Roulette table never open though in daytime. Disappointed, wanted to play that. Really nice facility and the adult hotel was better than some of the Vegas hotels I've been at. Great price too! Will come back for sure!
