21+3 Blackjack Slot Machine - Demo, Free Play ,Game, Casino

When it comes to playing online blackjack, 21+3 Blackjack is a good option. This casino game is played with six decks of cards. You can double on any total (except for blackjack) and also can double after splitting, and even if you don't have a blackjack, you can still double on a nine or an eleven. A suited trip pays 100 to one, while a straight flush pays 40 to 1. You can also win with three of a kind, which pays ten to one. This game features six-deck, 21+3-only decks, and can feature up to 50 cards. You can place 0.50 to 500 credits on your main bet. A side bet allows you to rely on basic strategy to win, and the game pays out if your hand is less than 21 points. The only drawback is that you can lose your side bet, which will deplete your bankroll. 21+3 Blackjack features ways to win four-of-a-kind, three-of-a-kind, flushes, and straights. This game has a limited bonus side bet aimed at novice players. A total of six decks of cards are used, and the house edge for the game is 0.48% higher.
