With this being the scenario, we’re going to talk you through what 21 Blackjack from RTG is able to provide to its players, and on if there are any special features within it to further enhance gameplay.

What to Expect from 21 Blackjack by RTG

Accessing this online table game from RTG won’t particularly present you with anything so different from other standard blackjack games. All of the same sorts of basic betting options are available, you’ll get the same sort of table setup on your screen, and considering that it’s an RTG game, the graphics and gameplay overall are very crisp and smooth.

21 Blackjack provides a single betting area for you to utilize, which means that there’s the possibility of betting on a single hand per round, and no more. You can use a Rebet function to make the same bet as you did in the previous round and there’s a Help button for you to open up some information from RTG about 21 Blackjack gameplay. Everything else is very basic, making this a good game for newcomers to play blackjack online for real money.

What Special Features Does It Include?

As far as betting is concerned, 21 Blackjack utilizes the basics of many blackjack titles. This means that while you can place basic bets on the cards that you’re dealt and whether you can get as close to or hit 21, there are one or two additional functions of the game that you can make use of, too. First of all, there’s the inclusion of the Double bet. This is made available to you when you’ve had your first two cards dealt. Should you choose to use this, your bet is doubled, and a single extra card is dealt out to you. This can be quite useful to use if you have a lower set of first cards.

To add to that, you have the chance to use the game’s Split function. This becomes available to you when you are dealt two cards that are of the same value. Should you use it, then the two cards are split into two separate hands and your bet is laid out on each hand. You can then continue hitting or standing on those two hands. If you choose to Split a pair of Aces, then you will only get the chance to take one more card for each hand.

Last of all, 21 Blackjack from RTG allows you to make an Insurance Bet. This is something that is active when the dealer’s face up card is an Ace. If you believe that the dealer has a blackjack, then you can use the insurance bet so as to stop you losing your own basic bet. This pays out 2:1 if you get it correct.

How to Place Bets in 21 Blackjack from RTG

Betting in the game is a simple process to undertake, as you can see the different chip values at the bottom of the table. These exist in the form of the €1, €5, €25 and €100 chips. There is also the inclusion of a €500 chip there, although this isn’t usable due to the game having a maximum overall bet limit per round of €100. The minimum bet per round is of €1. You can place a single chip on the betting area or mix chips together for alternate totals per round.

21 Blackjack doesn’t provide you with any sort of customization features, so you’ll always have the table with green felt and the playing cards in the style they’re visible in. This is quite the norm for RTG table games, but the developer utilizes high-quality graphics and animations anyway, so there’s not such a huge need for customizing things.

Where to Play 21 Blackjack for Real Money

To get started with some real-money action, you’d need to find a licensed online casino that offers Realtime Gaming table games. We’ve got a list of recommendations ready for you so you don’t have to do all the research yourself. Read each casino’s review and use our compare option to decide where you want to register and play.

The Payouts and Expected Return from the Game

The 21 Blackjack game has standard payouts for you to benefit from. So, if you manage to beat the dealer’s hand with a general higher total, then you’ll receive a reward of 1:1. Should you be dealt a blackjack, then you’ll receive a reward of 3:2. As noted earlier, a winning Insurance Bet will pay out 2:1. The only other payout that you can get from playing this game is if your hand and the dealer’s hand are exactly the same value. At this point, you receive your total wager back.

21 Blackjack also comes with an expected RTP rate of 99.44%, which is an amazing player edge. The house only gets a 0.56% edge when this game is in action, which makes it quite the appealing version of blackjack to play.

Why Not Utilize One of These Tips?

There are various ways in which players engage in playing online blackjack, so it’s generally better to find a strategy that works specifically for you. However, one piece of advice that is often good to follow, is that if you have a total of 11 from your hand, then it’s almost always good to use the Double function, as at least this way you stand to win a larger amount and don’t have any possibility of going bust.

Another piece of advice that is always good to adhere to, is always have a budget. If you go in with the assumption that you’re always going to lose at some point or another, then you stand more of a chance of coming away from the game when your bank balance is lower. This stops you from depositing more money that you really can’t afford to lose – and that’s a hint to use in relation to all types of gambling, online or offline.

The Attraction of RTG and Its Games

The Realtime Gaming brand is one that holds quite a lofty position in the online gambling world. Then again, it has been providing online content since 1998, so it stands to reason. Alongside 21 Blackjack, the company has created numerous other games. These include options like slots, such as The Big Bopper, Cleopatra’s Gold and Megasaur, amongst others. So, why not check them out for a bit of alternative entertainment?

Should you have the interest in playing any of these games from RTG, then you can access them at several online casinos on our recommended list.
