GoGo21 rules:
GoGo 21 is a card game based partly on the BlackJack rules and way of counting, and the object of the game is to place cards in such a way as to make 21 as many times as possible in each round. You can place each card in any column as long as the sum does not exceed 21. The current sum of the column is presented above each column. If you can’t place a card in a column you have to throw it away. Try to keep the number of cards you throw away to a minimum to increase your score.

Classic Blackjack rules:

The object of Blackjack is very simple: to achieve a total that is greater than that of the dealer, and which does not exceed 21.
You must consider your cards and your dealer's card and remember, if you go over 21, you lose.
You win if:
- Your total is higher than the Dealer's total.
- The Dealer goes over 21 or "busts".

If your total is the same as the Dealer's total it is a "stand-off" and you neither win nor lose.
If you go over 21, or the Dealer's total is greater, you lose.

The values of the cards:

- Picture cards (Jack, Queen, King) each count as 10 points.
- An Ace counts as 1 point or 11 points, whichever is better for owns of the hand.
- All other cards have their numerical value.

Blackjack is a combination of an Ace and any 10-points card.
