We've been to each of the local 'Seminole' casinos now since they've installed some of the 'Las Vegas' style Class III slots...so here is the rundown. 

Seminole Coconut Creek Casino-
I don't have a count on how many Class III machines they've installed...but the casino has been packed the 2 times we've been.  Most of the Class III machines will have a sign overhead letting you know they are the 'Vegas Style' slots.  That is actually quite helpful since it's hard to tell them apart sometimes.  They are scattered around the casino and usually consist of a whole row of machines.  The minimums, on average are 45 cents. 

The main thing I noticed was the Class III machines at the Coconut Creek Casino were BORING.  I'm not sure if this is the 'new' way of buying machines...but I didn't care for it.  They all have the same 'shell'...the only difference was the games on the video screens.  One screen was for the reels...the other for payout info and the name of the game.  It looks like they can easily change the games out by just flipping a switch.  There was no Wheel of Fortune that we saw...no Little Green Men...no Hot Hot Penny.  Maybe those machines will arrive when they change the remaining Class II to Class III.

The funny thing is...I actually played a few Class II machines and won more than the Vegas Style machines. 
**I would suggest to hit the Isle Casino in Pompano instead of Coconut Creek.

Seminole Hard Rock Casino-
Ok...this visit was fun.  They have changed a lot of machines over to class III and they even have the 'roulette' slot machines.  It works just like the real game...you place your bets and spin.  These were really hot in Vegas on our last trip and it was fun to see them again.  They had a good variety of games and machines that were Class III.  The casino is huge and definitely worth the trip if you like variety in your slot play.One thing to note is the signs that are above some groups of machines don't have the correct denominations.  I didn't mind...since it was fun to explore the casino. 

There is definitely a cool vibe in the place and I imagine when they do install the table games it will turn up the excitement even more.  It looks like they are going to move the poker pit and possibly put the table games in it's place. 
**Best of the 2 Seminole properties for slot play.  With the large entertainment complex attached and a hotel...this gives the Isle Casino, Mardi Gras Gaming and Gulfstream some stiff competition.  To keep up, the 3 pari-mutuals need to ramp up their entertainment offerings.
