Card games rarely end in the same form as where they start. The family of 21 games is one of the clear examples how a simple game, passed from table to table, can have such a different set of rules, when looking to other regions over the course of centuries.

A French Game With Continental Ambitions

The earliest references to vingt-et-un show that the was played in France since the late 1700’s, although precursors likely existed before that. The name is a direct translation of twenty-one, and the objective of the game was identical to what players know today: draw cards, approach 21, and do not exceed 21.

What made vingt-et-un popular was it’s simplicity. There was no special equipment required, the rules were easily explained in under a minute, and it scales from two players to a full table without hassle. By the 1800’s the game has spread through French society into broader Europe. It was carried by soldiers, merchants, and travelers across borders.

At this stage of the game there was no standard ruleset. It was more based on the shared idea, reaching 21, beat the dealer, and local players filled in the other blanks themselves.

How Regional Rules Created Different Games

The absence of standardized rules is the reason that the game diverged. Different regions adopted vingt-et-un, and applied their own logic to the ambiguous parts: what value’s were the face cards, when was the dealer obligated to play, what happened in a tie, and whether special hands carried bonus payouts.

In Finland the game evolved into ventti, a domestic variant that never made a full transition into the casino world. According to the ventti page of Kasinopartio, one of the most distinct features of ventti is it’s face card valuations. The jack has a value of 11, the queen 12, and the king 13, instead of the standard value of 10 that is given in normal blackjack. On top of that, the ace is worth 1 or 14 in ventti, instead of the 1 or 11 in blackjack. These differences change the math behind the game, and make it a higher-variance experience.

In Britain vingt-et-un got adopted and made the game pontoon. This had it’s own set of changes: the dealer’s cards remain hidden until all the players are done, and a five-card hand that does not bust, known as a five-card trick, has a bonus payout.

Pontoon, Blackjack, and Ventti Side by Side

Across the three variants, the shared DNA is instantly visible. They all have set 21 as the target, all three eliminate a players when they exceed the 21, and all of them have the dealer as the opponent rather than the other players.

The differences are in the details of the games. Blackjack has a value of 10 for all face cards, and a tie gives back the original stake to the player. Ventti has higher value’s for face cards and awards a tie to the dealer. Pontoon doesn’t show the dealer’s cards and adds a bonus payout for a five card non busting hand.

Why Blackjack Won the Casino Floor

When casino gambling got legalized in Nevada in 1931, casinos needed games with a predictable house edge and rules that were simple enough to be enforced consistently across dozens of tables at a time. Blackjack, with its simple face card value’s and clear dealer obligations, was clearly well suited for this. This made blackjack the standard version that is played in land based and online casinos today. The other versions remain home games, that are still fun to play with friends and family.¹⁾EDITOR NOTE: Check out the history of blackjack on this site for more information.
