TORNADO 21 - RULES
------------------

Tornado 21 is a card game from Yahoo! Games. Visit games.yahoo.com to play the
original (on-line) version.

BASICS
------
The game is bases on the popular card game "Blackjack", where you have to make
out a total sum of 21 using game cards.
In Tornado 21, there are five columns for you to place cards. To place a card
in a specific column, simply click on the column in which you would like it to
go. Creating a combination of 21 will clear the column and move the cards to
the scoring box on the right-hand side.
Each time you clear a column, you gain 21 points. Using two cards to create 21
will net you an extra 10 points.
You can also clear a column by stacking five cards that are equal to or less
than 21. The score you receive for clearing the column will equal the sum of the
face value of the cards. So, if you stack five cards that equal 18, you gain
18 points.

Face cards (Jack, Queen and King) are equal 10.
Aces are used as both 1 and 10 (if possible) - for example, if you have an Ace
and a three in one column, the sum will be "4 or 14". If you add a 7, the
column will clear (14+7 = 21). If you add an 8 instead, however, the new sum
will be 12 (4+8 = 12).

BONUSES
-------
Bonuses are earned when certain conditions are met, mainly when slots are
cleared in special ways. There are around a dozen bonuses. Good luck finiding
them all!

GOLD CARDS
----------
Some bonuses turn or add "Gold" cards to the deck.
Gold cards are good for two reasons:
1. When you clear a column that contains gold cards, the score for clearing
that column is doubled for each gold card.
2. When you clear a column that contains gold cards, a gap will appear in
the scoring box (in the right side of the board). The gap will be filled
with the score you will get the next time you clear a column. In other words,
the next time you will clear a column you get double points.

JOKERS
------
In some special cases, you may get a Joker to play. Jokers either complete
the sum in a column to 11 if the sum in it is 9 or less, or clear the column
otherwise.

BONUSES
-------
The following is a list of bonuses in the game, the points you get for
getting one, and what you need to do to get one.

BONUS			POINTS		DESCRIPTION
21 Large		65		total 21 using any 5 cards
Triple 7's Jackpot	65		7-7-7
21 Straight		30		6-7-8 or 8-7-6
Big Straight		30 		Q-K-A
Little Straight		65		A-2-3-4-5 or 2-3-4-5-6 in any order
911 Emergency		65		9-A-A
Double Jokers		350		2 Jokers (only)
5 of a Kind		65		Five A's, 2's, 3's, 4's, or 5's
Deck Cleared		65		play all the cards in the deck
Cleared Board		65		clear all 5 slots in only 5 turns

Greater Straight	65		slot totals in order: 16, 17, 18, 19, 20

If you get a clear-bonus (all bonuses except the last 4) using all gold cards,
you get a meta-bonus: All Golden, which multiplies the number of bonus points
by the number of gold cards.

GOLD CARDS
----------
Every time you get a bonus, one "normal" card in the deck will turn gold.
The "Cleared Board" and "Double Jokers" bonuses will turn three cards gold
instead of just one.
The "Lesser Straight" and "Greater Straight" bonuses add 5 specific gold
cards to the top of the card deck: 5, 4, 3, 2, and Ace, all of Spade.

JOKRES
------
There are 4 special rules to get a Joker
1. Clearing the same column 4 times or more in a row.
2. Getting 3 gold cards in the same column, or playing a card on a column
that already has 3 or more gold cards.
3. Getting a clear-bonus with 2 or more gold cards.
4. (get this!) Playing an Ace, 2, 3 or 4 of Spade, when the number of cards
in the deck yields a remainder of 1 when divided by 13 (i.e. if it's 1, 14,
27, 40, ...).
[This is to prevent an ever-lasting Goldrush]
