Rules and Strategy for Zappit 21

How to play Zappit Blackjack, a unique 21 variant by famed gambling games inventor Geoff Hall.

How to Play Zappit Blackjack, a Unique 21 Game by Geoff HallZappit Blackjack is by no means your typical game of 21. Yes, the basic rules exist, but players are given more options than ever before. Specifically, a player can “zap” their entire hand, tossing it aside and receiving all new cards; a virtual rewind, if you will. Best of all, it doesn’t cost a thing to do it. There’s no extra charge – no additional bets – you either Zappit, or you don’t.

This game is the patented brainchild of Geoff Hall, the famous inventor of multiple well-known gambling games, including his most popular creation of all, Blackjack Switch. He sold Zappit to Shuffle Master / Scientific Games, which has since distributed it into the land-based casino and online casino realms.

SG Digital chose to make some of the game’s rules customizable. As such, you’ll find the house edge can vary from one live or online casino to the next. When SG first debuted to game at the 2015 Global Gaming Expo, it came with a house edge of 1.24% (RTP 98.76%). The rules imposed by Bodog and Bovada online casinos deliver a slightly lower house edge of 1.15% (RTP 98.85%).

Any blackjack strategist will tell you that those are abysmal odds. The best blackjack games offer an RTP of at least 99.65% (edge 0.35% and below). If you’re playing for entertainment, Geoff Hall’s Zappit Blackjack is a great choice, but if it’s the best odds you seek, there are far better games to choose from.

With that being said, let’s move on to the rules section of our tutorial.

How to Play Zappit Blackjack

In Zappit 21, players are given the esteemed advantage of tossing out their hand for a new one. To zap a hand is to throw away all the current cards in that hand and be dealt a completely new 2-card hand to work with. You can only do this once per hand, and only if certain conditions are met.

A player may only elect to zap their hand away if its current total is 15, 16 or 17 points, regardless of how many cards make up that total. Some land-based casinos extend the zap-ability to totals of 18, but the rules we’re covering today – those found at Bodog and Bovada casinos, wherein the lowest house edge of 1.15% can be found – do not.

As a trade off for being able to zap these hands, the dealer gets one major advantage of his own. Any player hand that is still active (has not busted), and is not a natural blackjack (before or after zapping), will push against the dealer’s 22.

Probabilities state that the dealer will have 22 on 7.62% of all his hands, or about 1 in 13 hands. At the same time, based on basic strategy, player’s will be zapping 20.7% (about 1 in 5) of all their hands.

The following rules are applied by Bodog/Bovada:

Zappit 21 Strategy

Zappit 21 offers players more options than the average blackjack game. Along with choosing when to Stand, Hit, Double and Split, players also have the opportunity to “Zap” their hand away in favor of a new pair of cards.

In order to deliver a perfect strategy for Zappit Blackjack, we must include times when it is and is not appropriate to Zap a hand total of 15, 16 or 17, so that’s where we’ll start.

When to Zap on 15, 16 or 17

The zapping strategy is very simple. Follow these rules and you’ll do fine:

  • Hard Total of 15, 16 or 17Always Zap
  • Soft Total of 15, 16 or 17 Never Zap
  • Paired 8-8Split against Dealer’s 6 or 7; otherwise Zap
  • Paired 9-9Zap against Dealer’s 9, 10 or Ace; Stand against 2, 3 or 7; otherwise Split

If your hand does not meet the above requirements, or you are unable to Zap according to the above strategy, abide by the following Hard Hand, Soft Hand and Paired Hand charts below.
