| 4-Line Jacks or Better is an online casino video poker game played between the dealer and player. It is played with deck of 52 cards. The player has to hit a winning combination on a five card poker hand. |
| 4-Line Jacks or Better differs from the standard Jacks or Better online casino game in that there are 4 lines of cards in this game. Each line has different deck of cards. Winning combination on each line is treated as a different hand. |
| The player chooses the bet amount. The bet is placed for one line and the amount is multiplied with 4 and the total sum is reduced from the players account. The maximum bet is five coins per line and the minimum is one coin. |
| After the bet amount is placed, the cards are dealt. The player can choose to keep the cards or can replace them. The cards which form a winning combination are automatically held by the computer. This is called as auto hold feature. The player can hold as may cards as he wants. The cards are then checked for winning combination and the combinations are paid according to the payout table. In case of winning combinations on multiple lines, the winnings are added up. |
| If the player hits a winning hand, then he can choose to Double the payout. The player wins double the payout amount if the one of the 4 cards chosen by the player is greater than the card drawn by the dealer. If it is less, the player gets nothing and in case of a tie, the player wins just the payout amount and no doubling takes place. |
| The player can also do a Half Double where only half of the payout amount is doubled and the half is credited to the player account. |
