Casino and poker apps are one of the best represented sectors within the Google Play Store.

It should come as no surprise; the popularity of poker exploded at the turn of the century with online gambling, while hole-card cams on TV turned it into a spectator event. Those players at the top of the sport now earn huge amounts of money -- Daniel Negreanu has taken home more than $35 million in winnings, and vast amounts more from sponsorships and endorsements.

Whether you want to follow in Daniel's footsteps or you just want play casually with friends and family, there is certain to be an app to meet your requirements.

Here are some of the best casino and poker games for Android.

Texas HoldEm Poker Deluxe [No Longer Available]

Texas HoldEm Poker Deluxe is one of the best-known and widely-used poker apps. It has been downloaded more than 30 million times and has in excess of 300,000 four or five star reviews.

What makes it so popular is its integration with other platforms -- once you install the app, you can battle against users on iOS devices and all Facebook users. That gives you a possible competitor base of 18 million active users.

As you'd expect, there are countless tournament styles and table types, including shootout and sit-and-go. It also offers virtual gifts, snacks, and other goodies which you can offer to fellow gamers.

World Series of Poker [No Longer Available]

If you fancy ending up on a real-life table in Las Vegas, London, Paris, Sydney, or Tokyo, this is the app for you.

If you're victorious on one of the app's pro tables or you rise to the top of the app's leader-board, that's exactly what you can expect. They'll even throw in a free hotel stay! Aside from this attention-grabbing headline, players who are looking for a day-to-day deal will not be disappointed -- the app will give you a handful of free chips for every four hours of play.

The app features the well-known Texas HoldEm and Omaha style tournaments, as well as several more off-piste ones. They also claim to be the best app for improving your poker playing skills thanks to the most extensive stats tracking in any Android-based poker game.

Finally, if you need a break from cards, you can still gamble within the app -- it offers mini slot machines which can either be played on their own or on breaks in between hands.

Big Win Slots [No Longer Available]

We're not convinced that virtual slot machines (or real life slot machines) are a particularly good idea -- too much of it is down to chance rather than player skill.

Nonetheless, some people thrive off the adrenaline of chance, and this is a great app for those people.

The app features machines with multiple themes and has both 3-reel and 5-reel offerings, each of which have different bonus games, pay-lines, and jackpots.

One of the nice things about this app is that reward points earned can be spent across all its gambling apps, including the highly popular Solitaire Deluxe.

GSN Casino [No Longer Available]

GSN Casino offers four main types of games: slots, bingo, video poker, and blackjack.

Unlike some of the other apps in the store, all the games are given a pop culture twist. It means you can play "Deal or No Deal" slots, "Wheel of Fortune" poker, or "Ghostbusters" bingo, among others.

There are millions of players already using this app, some undoubtedly lured by a free 12,500 tokens when you sign up for the first time.

If you like big, bold, and flashy graphics along with a huge variety of styles and themes, no other casino app in the Play Store comes close.

Roulette - Casino Style [No Longer Available]

Are you the type of person who wants to put everything on red? Downloading Roulette - Casino Style will let you fulfil your dreams without leaving your sofa.

It's the number one roulette app on Android, and for good reason. It offers American- and European-style tables, twenty different types of bets, an hourly chip bonus, and a range of achievements to unlock.

The only drawback is that your winnings (and losses) are listed in USD. There is no alternative to change it to a different currency -- you'll have to use a currency converter.

Caribbean Stud Poker [No Longer Available]

Cocktails, coconuts, and Caribbean Stud Poker! Download this app to recreate your last vacation with a more tropical and laid back approach to gaming than some of the better-known and widely-used apps.

For those readers who are not aware, the Caribbean stud game differs from traditional poker games in that instead of playing against other players, you play against the house. In terms of the app, it means for a much less frenetic experience.

This is the only officially licensed Caribbean Stud Poker mobile game, and with a 200:1 payout ratio it's also the most generous. It's a must-have if you want a break from Texas HoldEm.

Zynga Poker [No Longer Available]

This is the same game that all your friends are nagging you to play on Facebook.

Features of the app include the ability to play both competitively and casually, the ability to win countless free chips with mini competitions every day, and an experience that syncs and is accessible across all platforms and by all devices.
