Now, let us take a look at the side bet that gives this game its name. The 21+3 side bet will award you different payouts if your initial hand and the dealer’s up card form a poker hand of three cards. The possible combinations that 21+3 will award are as follows:

As you can see from the game’s blackjack rules, there are plenty of ways to win the side bet. And since they are not very common, they pay pretty well. But, enough about the rules. Let us look at the production value of the game.The graphics are quite pleasant and non-intrusive. You can see that the moment you start playing 21+3 Blackjack online.

The game is in 2D and features oversized buttons in its UI because it is developed with a mobile-first approach. When it comes to settings, there isn’t a lot of them to play with, but there is one toggle that every blackjack game should have – you can make the game, not ask if you want insurance. Most players that rely on basic strategy will appreciate that.

21+3 Blackjack Tips & Strategy Chart

The basic strategy chart for 21+3 Blackjack online is pretty much standard. It features a specific soft totals section because you can only double on hard totals of nine through eleven, so it’s very newcomer-friendly. The hard totals and pairs section is the same as with almost any S17 blackjack game. However, remember that it does not cover the side bet, as the decks are shuffled after each round, and there is no way to predict what cards will come up.

21+3 Blackjack Basic Strategy

The basic blackjack strategy above will help you lower the house edge to just under half of a percent. However, our next 21+3 Blackjack tip is to remember that it will not eliminate the casino’s advantage. You will still be at a disadvantage in the long run. There is a way you can tip the scales, though, and that’s by claiming a bonus to play with. For example, Mr Green offers a great welcome bonus pack, and you can play a wide variety of games with it.
