What Is a 21 3 Side Bet in Blackjack?

In blackjack, the 21+3 side bet is a wager that the player’s first two cards and the dealer’s up-card will form a poker hand. The side bet pays off if the player’s hand is a flush, straight, three-of-a-kind or straight flush.

The side bet does not affect the main blackjack wager and players can make the 21+3 bet regardless of whether they win or lose their main hand.

The 21+3 side bet is offered at many online and brick-and-mortar casinos. The bet is usually placed before the player receives their first two cards.

PRO TIP:A 21 3 side bet in Blackjack is a wager placed when the player is dealt a hand containing three 7s. This bet pays out at 30:1 odds, making it a potentially very lucrative bet. It is only available in some casinos and should be used cautiously as it carries a higher house edge than the standard game.

To make the 21+3 side bet, players simply place their chips in the designated betting area on the blackjack table. The amount of the wager varies from casino to casino but is usually $1 or less.

The 21+3 side bet has a relatively high house edge, ranging from 7.28% to 11.11%. This means that for every $1 wagered on the side bet, players can expect to lose an average of 7 to 11 cents over the long run.

Despite this, the 21+3 bet can still be profitable for players if they get lucky and hit a big hand. For example, a player who hits a straight flush will receive a payout of 50 to 1, meaning they will profit $49 for every $1 wagered on the side bet.

Despite its high house edge, the 21+3 side bet can be an exciting addition to any game of blackjack. Players who are looking for some extra action should give it a try next time they’re at the casino.
