Side-Bonus® Blackjack™ was in ABBIATI's Booth, at ICE-London 2019.

* Side-Bonus® Blackjack™ Uses Two Optional Side-bets for any Blackjack games (Ten-20® Bonus™) and (Contrast® WIN™).

RULES:

* First Side-bet: Ten20® Bonus™, is a Side-bet for any Blackjack game.

The Ten-20® Bonus™ wins when the Player’s Initial Two-cards Blackjack-hand add-up to a 10 or 20 points.

1. Player may wager an Optional Side-bet (Ten20® Bonus™).

2. Player receives their Initial two-card Blackjack-hand.

3. The Ten-20® Bonus™ wins when the Player’s initial Two-card Blackjack-hand add-up to 10 or 20 points (see Pay-table).

Otherwise the Ten-20 bet loses.

* Second Side-bet: Contrast® WIN™, is a Side-bet for any Blackjack game.

1. Player may wager an Optional Side-bet (Contrast® WIN™).

2. Player must have both a red and black suit in his 2-card starting hand.

If the Player doesn’t have a red and black suit starting hand, then his Contrast-bet automatic loses.

3. Player complete his Blackjack game.

3a) If Player beats the Dealer, then his Contrast-WIN (if any) will win 3 to 1.

3b) If Player ties with the Dealer, then his Contrast-WIN (if any) will win 1 to 1.

3c) If Player lose to the Dealer, then his Contrast-WIN (if any) will lose.

* The Question is what do you think about (Side-Bonus® Blackjack™) and WHY?

P.S. Any Comments are Welcome Good/Bad (Please give Comments with reasons) so I know WHY and learn from it.

say this, these bets are simple to understand and that"s

a big deal for a casual gambler. Many times I have sat at

a table when someone asked for a explanation of a side

bet only to be put off by a convoluted explanation of a

complicated bet, and when I say complicated I mean

complicated to a new player.

Thanks for your comment.

I know what you mean with some Side-bets (complicated to a new player) and some are complicated to old player too.

The Ten-20 bet is a solid idea. My problem with it is that I'd be stuck actively hoping to NOT get a blackjack and I don't want to go there. The whole point of the game (and the reason I'm sitting at the table) is to GET blackjacks.

The contrast wager seems fun (maybe even countable) and, if I get a black/red blackjack, I'll make 3-2 on the main game and 3-1 on the side (or at worst tie for 1-1). That's much more pleasant to contemplate.

I like the fact that , as compared to the similar lucky ladies and Kings ransom side bets , you cannot be dead after seeing your first card. No matter what you still have a chance to make a winning hand.

As a first approximation, assume infinite decks.

For the 10-20 sidebet, every 169 deals the player will get 5,5 1 time, another 10 (2,8 8,2 3,7 7,3 4,6 or 6,4) 6 times, an A,9 or 9,A 2 times, and an X,X 16 times. Thus, the player's edge is

100%*((1*22 + 6*10 + 18*3) - 144)/169 = -7.1%

For finite decks, the "1" and "16" will decrease, while the "6" and "2" will increase.

For the Contrast sidebet, the sb will lose outright 50% of the time. When it doesn't lose outright, it will pay 3 about 41%, 1 about 8%, and lose the remaining 51% (the actual percentages depend on how the player plays, and on how split hands are resolved in terms of W/P/L). Combining gives a loss about 75.5% of the time, a win of 3 about 20.5%, and a win of 1 about 4%. Thus, the player's edge is

20.5%*3 + 4%*1 - 75.5% = -10%.

I would be disinclined to play either of these sidebets.

On the plus side, BJ's pay 3:2, and the dealer Stands on S17.

P.S. michael99000, you seem to have misread the rules: the 10-20 sidebet is resolved on the player's first two cards only.

Edit: the equation "100%*((1*22 + 6*10 + 18*3) - 144)/169" I typed is correct, but I miscalculated the result: it should say -4.73%.

Hi DogHand,

Both of your House-Edge estimate is wrong.

I will post the House-Edge of the 2 Side-bets here next week, If nobody done it by then.

Thanks for your comments.

How did I misread the rules ? I know it’s based on the first 2 cards.

In Kings Ransom and Lucky Ladies, if your first card dealt is not a 9, 10, J, Q, K, or A, you have no chance to win.

In this 10-20 bet. No matter what your first card is , you still have a shot to win.

All this while acting like you're not paying attention. Fun stuff.
