If you like to play card games in the main, maybe roulette too then once again, the best choice by far is at the casinos
that offer a download option. Casinos like the excellent 32red
and it's sister Dash casino offer lots of different variants
of both with excellent customer service and high table (and withdrawal!) limits. The same can be said of
Royal Vegas although the cashouts are a day slower with
the trade-off that VIP loyalty bonuses are better.
Live dealer versions of blackjack, roulette and baccarat are relatively commonplace now and all the above have live casinos built in but another good (and different) option is at MyBet casino which unlike those above, doesn't require a download.
If you also like "Casino Hold'Em" then you'll find the usual live dealer games plus that at both Sky Vegas and the excellent Paddy Power, again with no need to download software. Paddy Power also has large table limits up to £10k a shot on roulette and £1,250 on blackjack!
If that isn't enough information to make decision then you can check out a very in-depth live casino review written by a friend of mine who plays them a lot and really knows his stuff!
If you want to play slots online then where you play will depend on what you want. If you aren't too bothered about playing the games from land based casinos then no doubt about it, casinos that offer a download version of Microgaming's software have the widest choice of games: 32red is arguably the best example or if you like to play with regular VIP bonuses, either of Roxy Palace or the long-time stalwart River Belle casino would be good choices and you'll find 400+ slot games there.
Although Microgaming casinos have some well-known brand slots like Game Of Thrones, Battlestar Galactica, Tombraider and Playboy slots, if it is land-based names you are after then you'll find games like Book Of Ra and Where's The Gold at MyBet Casino who have Aristocrat and Novomatic slots while BetVictor has a good selection of Novomatic games like the popular Book Of Ra and IGT games like Cleopatra. IGT's slots also feature heavily at Paddy Power Games while you can find easily the best selection of WMS slots at Slots Magic casino (formerly Jackpot Party).
If you want to get a better feel for what type of games each of the above software platforms provide then you'll find a lot of videos of the games on the Slotjunkies website with each platform having it's own section. The site also helps slot gamers understand the very important concept of variance too.
At the risk of getting boring, once again I am going to say that casinos that use Microgaming's software have easily the best range of video poker games. From 1 hand to 100 hands and a whole load of different bonus pokers, you'll find the usual suspects like 32red and Royal Vegas are the best places to go.
Once upon a time I would have pointed you straight to Intercasino as their video poker games were very similar to the IGT ones you play in land casinos but since they went to a browser-based casino product, their video poker is pretty rubbish now. But they are still a decent casino with a diverse portfolio of casino games and they have an excellent reputation.
Playtech's software isn't too bad for video poker to be fair: not quite as much choice but much quicker to download and it has a very good overall range of games. Again, you'll need the download version to get the best options but you could do worse than play at the excellent Genting casino, which also has live dealers and a good range of table games.
Talking of live dealer games, I have written a specific live casinos review which gives you a good overview of what is available and the best places to find your favorite live games like Baccarat, Blackjack, Roulette and even 3 Card Poker, probably my favorite game of the bunch especially as RNG versions are pretty boring.
