Maximize your score by making 21's as fast as you can.
Tap one of the four columns to place the top card from the draw pile in it. The number over the draw pile shows the number of cards remaining in the draw pile.
You can place a card to any column provided that the resulting total of cards in the column is 21 or less. A "play card here" sign is displayed below each column where it is possible to place the current card. The number at the top of each column shows the current total of the cards in that column. Picture cards (Jacks,Queens, and Kings) have a value of 10; Aces can be either 1 or 11.
When the total of the cards in a column equals 21, the cards in the column are cleared. You can also clear a column with a "Five Card Charlie" by placing five cards in the column, as long as they total 21 points or less.
The two Black Jacks (the Jack of Spades and the Jack of Clubs) are special cards. Playing one on any column will clear that column, no matter what the total. As a reminder, when a Black Jack appears, the words "Blackjack Attack" will appear.
If you can't or don' want to play the top card on the draw pile, you can tap on the discard pile to move onto the next card. If you try to play a card on a column where it won't fit, the column will turn red for one second, and you will be unable to play the card anywhere. However, if you tap on a column while it's red, the last card in that column will "burn" away. Depending on the cards remaining, this may make it possible for you to play the top card from the draw pile onto the column.
The clock begins at five minutes and counts down. You will receive a time bonus based on the amount of time left on the clock at the end of the game. If the clock reaches 0:00 before you have played your last card, the game ends immediately.
Tap any of the four columns to move the current card to that column. Or Tap the discard pile to discard the current card.
Tap on a column while it's red to burn away the last card in that column.
You'll get 50 points for each column cleared by a "21", 75 points for each column cleared by a Blackjack Attack, and 100 points for each column cleared by a Five Card Charlie. (If a column is cleared two ways at the same time, the higher point value applies. For example, if you put a Black Jack on a column, and it's the fifth card in the column, you'll get 100 points for the Five Card Charlie, not 75 points for the Blackjack Attack.)
At the end of the game,you'll receive a time bonus:
(1000 * Time Remaining)
Example: littledebbiecleared 9 columns with 21's, 2 columns with Blackjack Attacks, and 1 column with a Five Card Charlie. She had 2:45 seconds remaining on the clock.
(9 * 50) + (2 * 75) + (1 * 100) + (1000 * 165) = 1250
Tips & Strategy
Even though there is no point penalty for discards, try to avoid discarding because it means that you will end up making fewer column-clearing moves.
Always create a 21 when you have the chance to. Keeping as many open columns as possible reduces your chance of having to discard.
The closer a pile gets to 21, the fewer the cards that can be played there. If all your piles are close to 21, you run the risk of having to discard or burn several cards in a row.
Remember that 16 of the 52 cards have a value of 10 (about 30% of all the cards) so try to create columns with 11 in them, which will combine with any 10 to form a 21.
Group your low cards together, if you don't need them, to form Five Card Charlies, which give you the most points for a column-clearing. But don't go out of your way to make Five Card Charlies, or you'll deplete your supply of low cards that you need to clear those columns with 17, 18, or 19 points.
There are only four aces and two Black Jacks; try to keep track of how many you've seen so far. If you can, loosely keeping track of all the cards will help you figure out when to burn and replace a card.
