RealTime Gaming 21 Blackjack Review — Where to Play It in 2023
For many players, RealTime Gaming is a studio synonymous with online gambling. When most developers left the American market as a result of 2006’s Unlawful Internet Gambling Enforcement Act, this one stuck around to offer real-money betting entertainment.
Today, we’ll be going back to RealTime Gaming’s 21 Blackjack online, a retro classic that has been updated to work with modern web browsers and mobile devices. Revisit its rules and check out some great online casinos that still have it in stock.

Detailing the RealTime Gaming 21 Blackjack Rules

If you’re unfamiliar with the basic idea of blackjack, our dedicated “Blackjack Rules” page can give you a quick crash course on the essentials. Here, we’ll analyze some of the specific RealTime Gaming 21 Blackjack rules that may differ from similar games.
For starters, the rulebook doesn’t tell you how many decks of cards are in play because this aspect is set by the casino operators. In our experience, most sites tend to stick to six standard 52-card decks. The rules for the house are the following:
- The dealer will draw cards until 16 points at minimum. Once they reach 17, they’ll either hit again if their hand contains an Ace or stand if it doesn’t;
- Peeks for blackjack are performed whenever your opponent displays a 10, Jack, King, Queen, or Ace;
- 21 Blackjack by RealTime Gaming will propose that you get insurance when facing an Ace, but you should skip this option to maximize your returns.
Betting limits are the other customizable feature of this title, although we encounter the $1-$100 range quite frequently. Splits are always an option when your first two cards bring the same number of points. You may re-split two times to create three hands, but keep in mind that only one re-split is permitted on mobile.
Doubling down is the other move you could go for before hitting a hand for the first time. Much like splits, you need to double your wager to perform it. Here, only one extra card is drawn, so doing it on 9-11 point totals gives you the best chance of beating the dealer.
An Easy Way to Try the Game for Free

Our RealTime Gaming 21 Blackjack review recommends testing a demo of this game before wagering real money. Its payouts are more than decent, but the retro graphics and animations won’t appeal to everyone out there. Fortunately, you won’t need to jump through endless hoops to play for free. Follow these easy steps and start in a couple of minutes:
- Out of the three casinos on our list, Uptown Aces is the only one that doesn’t require any registration to start playing. Select it, click on any of the thumbnails on the homepage, then “Table Games,” and find this release. If you want to play RealTime Gaming’s 21 Blackjack online for cash, you might want to check out the bonuses of the other two operators at a later point.
- Once the table appears, turn your attention to the top-right corner to check your balance. It should be at $1,000, with the betting limits displayed on the upper-left side. Click on any of the playing chips to place one on the circle in the middle.
- At this point, the “Deal” icon at the bottom-right should be highlighted in green. When you’re ready, tap it, and the round will commence.
- When the cards are distributed, you’ll see four new icons appear where “Deal” was. 21 Blackjack by RealTime Gaming will give you the best possible returns if you use basic strategy. Those who are not acquainted with this approach can check out our dedicated “Blackjack Strategy” section from the gray bar at the top.
21 Blackjack by RealTime Gaming: House Edge & Payment Info
Blackjack Pays | Regular Wins | Insurance Pays | RTP |
---|---|---|---|
3:2 | 1:1 | 2:1 | 99.46% |
Much like its rules, the payout table of this product doesn’t stray from convention. This is great for players, as some virtual games of 21 pay 6:5 or 1:1 for a natural instead of the traditional 3:2. If the version you’re playing comes with a 6-deck shoe, you can expect a house edge of 0.54%, which is typical for vanilla Blackjack but lower than almost every other casino game out there. Remember that using basic strategy is a must for the best results over the long term.
Final Summary
RealTime Gaming 21 Blackjack online doesn’t have side bets, fancy graphics, or other bells and whistles. However, the game gives you a fair shot at winning through its low house edge, which is the most important factor for any prudent player. This title is as good as it was 10 years ago, with the addition that you can now play it on any modern tablet and smartphone.
If you’d like to give it a go, the three operators at the beginning of this article are all excellent choices. Real-money players can benefit from hefty promotions, regular & crypto banking methods, and solid customer support.
