Frequently Asked Questions

What is Pontoon and how does it differ from Blackjack?

Pontoon is the British version of Blackjack with key differences: dealer wins all ties, you must hit on 14 or less, both dealer cards are face down, and Five Card Trick (5 cards under 21) beats regular 21. Pontoon (natural 21) pays 2:1.

What is a Five Card Trick?

A Five Card Trick is when you draw 5 cards without busting (going over 21). It pays 2:1 and beats any regular hand except a Pontoon. This rule encourages aggressive play when you have 4 cards.

Why does the dealer win ties in Pontoon?

The dealer-wins-ties rule is a significant house edge contributor in Pontoon. It means you need to beat the dealer outright - no pushes. This is partially offset by the 2:1 payouts for Pontoon and Five Card Trick.

Is Pontoon better or worse than Blackjack?

With optimal strategy and good rules, Pontoon house edge can be as low as 0.17-0.38%, comparable to good blackjack games. However, the strategy is more complex due to no visible dealer card and different playing rules.
