Introduction

Best Free Casino Games Online

Double Up is a casino game I noticed at the D casino in Las Vegas on November 1, 2013. It is an easy game to learn and to play, and the correct strategy is simple. It features two zero-house-edge side bets.

Rules

The game is played with a single 52-card deck, shuffled after every hand.
Cards are scored as in blackjack, except aces are always one point.
Play begins with the player making an Ante Wager and an optional Red or Black wager.
The Red and Black wagers may not exceed the Ante Wager.
The dealer will deal three community cards face up.

The player may either stand or make a Double Up wager, which may not exceed the Ante wager.

The dealer will deal a fourth and final community card face up.

If the total points equals 40, then Ante and Double Up wagers will pay 2 to 1.

If the total points exceed 30 or are less than 20, then Ante and Double Up wagers will pay 1 to 1.

If the total points are between 20 and 30 inclusive, then Ante and Double Up wagers will lose.

Strategy

The player should make the Double Up wager with 12 or less or 24 or more points. Otherwise, stand.

DoubleU Casino is one of the best online casino simulators; at least, one of the best popular. Bright and festive, it won’t provide you with real money rewards, but will help you with spending it. No need to download DoubleU Casino apps; all the games can be accessed via Facebook Gameroom or just your browser.

Graphics 9/10

Luxury and glamour are a little over the top in its design, with no moderate sureness that follows the real rich things. Neon and loud music, coins dropping sound and golden sparks, bright colors in excess and endless zeroes in sums pursue you and chase you into playing.

The designers deserve their share of respect for not making that mayhem we’ve seen in other casinos, preferring to deliver it clear and easy to figure out even for those new to it.

Sound 9/10

It’s a rare case: an in-game music one can really enjoy. Piano and trumpets, bass and drums sound like a live band playing on the casino’s stage, taking your reason away and setting your mind on risking and taking chances. The music sounds quite modern but works the prewar wonders of mind. As for game sounds, they are just what you might expect from dealing cards or working slot machines.

Gameplay 8/10

It seems that the slot machines out there are very numerous. Each one features its own visuals, with a brief tutorial on winning combinations. Be wise when selecting a machine and placing your bets. Though millions on your virtual account may get you into vertigo, they are just as easy to waste (heh, we’re saying that as if they were real!)

There are regular slot machines, video poker, and all that you can play alone. None of the games presented here offers rewards as real money. You only can purchase chips to spend them on your bets, and, if you’re lucky, get more chips. Even if you manage to spend all you have, don’t hurry out for another one. You can spend some real cash on virtual chips, or try to get rewarded for your activity. Video poker with small bets will be enough to spend some time with minor losses and then get rewarded for your consistence.

Will DoubleU Casino review gaming process? The answer is probably no. All these games are for one, with no social elements except for some competition among your Facebook friends.

Lasting Appeal 8/10

Even if you just want to try each of slot machines or card games once, it will take you long. Some of them may attract you for longer. But DoubleU Casino is not the only one around, and not even the only one on Facebook. So other ones may redraw your attention even before you explore all of DoubleU’s slots.

The Verdict

If you like virtual casino aesthetics, and it does set your mind right and let you relax, we’d recommend spending some time in this one. With no need to install anything to your PC, it’s available also on your mobile devices under the same Facebook account.

Pros:

No need to download DoubleU Casino;
Various slot machines and video poker;
Rich graphics and luxurious music;
Moderate system requirements;
Instructions go with any slot machine.
