Pontoon Strategy

Can we get the definite winnings?

This article is NOT about Blackjack, but about Pontoon.

In the basic strategy (BS) of Pontoon, the player's hand is 10 and the dealer's face-up card is 2-8, double down is recommended.

Since 10's cards are not used in Pontoon, the strategy is different from the one in Blackjack.

Following the BS, I wonder how we would win at doubling down.

So I conducted a Pontoon experiment on both 10-doubling vs D6 and 10-doubling vs D8.

One more chart.

When we double down on 11, the BS says that we should do it against the dealer's 2-9.

As well as the 10-doubling, I conducted the experiment on both 11-doubling vs D6 and 11-doubling vs D9.

Then I put together the two kinds of experiment into one video.

This video consists of 23 scenes selected from all.

The former part is about the 10-doubling.

The latter part is about the 11-doubling.

The playback time is about 15 min.

The Result of 10-doubling

The following graphs show the results gained by the 100 data each.

Is it the rate as you expected?

When the player's hand becomes 12-16 by doubling, he chose surrender.
So the losing rate is high.
Surrender here is generally forfeit.
It's a Pontoon word.

The winning rate except for a tie
as follows:

vs D6 63%    vs D8 40%


The chip's fluctuation

vs D6 +24 chips    vs D8 +3 chips

(Bet Amount: 2 chips every time)

The Result of 11-double

The following graphs show the results gained by the 100 data each.

We must understand we would lose at a rate of 1/4.

The results of 10-doubling vs D8 is more preferable than this result.

The winning rate except for a tie
as follows:

vs D6 72%    vs D9 52%


The chip's fluctuation

vs D6 +84 chips    vs D9 +44 chips

(Bet Amount: 2 chips every time)

★Considerations★

When doubling down on 10 vs D's 2-8, we would win at a rate of 40-63%.

That's based on the experiment.

Considering no use of 10 cards, I think just hitting 10 is a better way against D's 7 or stronger.

Actually, the player had to choose surrender when his hand became hand 12-16 by doubling, against D's 8.

In the BS, surrender hand 12- 16 by doubling is recommended when the dealer's face-up card is 7 or stronger.

From this and the winning rate, I will double down on 10 against Dealer's 2-6 only.

When doubling down on 11 vs D's 2-9, we would win at a rate of 52-72%.

That's also based on the experiment.

Many players know the dealer's 9 is rather strong.

Some of them hesitate to double down, seeing the card.

However, we shouldn't miss 11-doubling, because it's so special.

Taking a picture card, we definitely win at hand 21.

It's a great merit in Pontoon.

If you fail in doubling, all you have to do is to shout "Surrender."

That's all.

I hope Pontoon will get more popular.

Bye.
