Detailed guide
Jangttaeng Card Game
Check the computer's card and the user's card on the game screen and proceed with the game.

How the outcome is decided

The game first checks whether each side has a pair. If both sides hold two cards with the same number, the higher pair wins. If only one side has a pair, that pair wins immediately over a mixed hand.

What happens when there is no pair

When both hands are mixed, the two card totals are added and reduced with modulo 10. The hand with the higher remaining value wins the round.

Swap decision strategy

Because you can replace only one card, the visible computer card matters. Sometimes keeping a balanced hand is safer, while other times a bold swap can improve your chance of building a stronger pair or better total.

Bankroll flow

The round payout follows the selected bet amount. Winning adds the chosen amount to your money, while losing subtracts it. If your money reaches zero, the round ends and Retry resets the bankroll to 500.

FAQs

How do I win a round?

Pairs are compared first. If there is no pair advantage, the higher sum modulo 10 wins.

What happens when my money runs out?

The game shows a game over style outcome for the bankroll and offers Retry so you can reset to 500 and play again.

Can I play on mobile?

Yes. The layout is responsive, and the card area and control buttons are arranged for both desktop and mobile screens.
