Chinese Blackjack is also known as 21-point, ban-luck (Hokkien), ban-nag (Cantonese), and x dch (Vietnamese). The game is played in South East Asia and resembles conventional Blackjack.

In blackjack, the cards that are better for the player are the high cards, specifically the 10, J, Q, K, and A. This is because these cards increase the probability of getting a blackjack (an Ace and a 10-value card), which pays out at a higher rate.

A basic betting strategy is simply to double the bet after losing a hand, also known as the Martingale system. This can go for multiple hands in a row until you win at blackjack.

Blackjack naturally has a mathematical percentage that favors the house, although the payout percentage varies by the skill level of the blackjack player. Online games use random number generators (RNGs) to ensure their odds match the payout of land-based casinos.
