FAQ's

What is 21+3 Blackjack by Felt Gaming?
21+3 Blackjack by Felt Gaming is an innovative version of classic blackjack that adds a poker-inspired twist. Alongside your main bet, you can place a 21+3 side bet that pays out for hands like flushes, straights, or three-of-a-kind. With a 99.5% RTP and low volatility, it offers frequent wins and plenty of excitement for all types of players.
How do I play 21+3 Blackjack?
The goal remains the same as standard blackjack — get as close to 21 as possible without going over. After placing your main bet, you can add a 21+3 side bet before cards are dealt. You then decide whether to hit, stand, split, or double down, depending on your hand and the dealer’s visible card.
Can I try 21+3 Blackjack for free?
Yes. You can play the demo version at blackjackseal.com to get familiar with the game’s layout and side bet options before wagering real money. Once you’re comfortable, switch to real play and test your strategy for bigger rewards.
What makes 21+3 Blackjack different from regular blackjack?
The 21+3 side bet makes this version stand out. It combines your two cards with the dealer’s upcard to form poker-style hands — such as flushes, straights, or three-of-a-kind — each offering high multipliers. This adds an extra layer of fun and potential profit without changing the main blackjack rules.
How does the 21+3 side bet work?
When you place the 21+3 side bet, you’re wagering that your two cards and the dealer’s face-up card will form a qualifying poker hand. Depending on the combination, payouts can reach up to 100:1. It’s an optional bet, but it can add significant excitement and potential big wins to your game.
What strategies work best in 21+3 Blackjack?
Stick to basic blackjack strategy for the main game — always split Aces and 8s, and double down on 11 when the dealer shows a weak card. Use the 21+3 side bet sparingly; it’s best treated as a fun add-on rather than your main tactic. Managing your bankroll smartly ensures longer play and steady returns.
Is 21+3 Blackjack suitable for beginners?
Yes. The game keeps the familiar blackjack structure while introducing an easy-to-understand side bet. New players can enjoy frequent wins thanks to its low volatility and experiment with the 21+3 feature without added complexity.
Can I play 21+3 Blackjack on mobile?
Absolutely. Felt Gaming optimized the game for all devices, ensuring smooth performance on both desktop and mobile. You’ll enjoy crisp visuals, quick gameplay, and seamless controls — perfect for real-money play anytime, anywhere.
