At the start deal six cards face down and one card in the centre face up to be your add on card and your discard pile. Your end hand points will be added to this card but will probably change throughout the game. At the start each player pays a small fee. The betting is the same as in poker.
Two to four players may play.
Six cards are dealt to each player.
Two or one jokers are needed.
Twos - are draw cards whatever the colour. Discard them and any cards you want to get rid of after the two and collect replacements until you have six cards again.
Eight - adds ten points to any card you want but nothing but an eight point card by itself. Used as a attachment which means that it will not count as a card in your end hand. See eights under the subheading rules.
Ace - can double the points of your whole hand. Used as a attachment.
Face cards - a normal point card worth 10 points or used as a draw card.
Five - a five will change your starter card or can be used as a normal point card (five points).
Red cards - are either used as a draw card or a normal point card.
Even number cards - are used as a draw card or a point card worth the number on it.
Jokers - can be any of the above. Used as a attachment.
All these are explained under rules after the second paragraph.
The game has three rounds or you can choose yourself. If two players have exactly the same points in their end hand then the player who uses the least amount of cards to make the hand wins. You can fix the end card hand amount at the start of the game e.g. if you play for the end hand to be a two card hand you can only put down two cards at the end of the game as your end hand but some cards that are put down arent counted. These cards are called attachments.
The betting is the same as poker. You can stay, raise or fold. The first player places his bet or can stay and carries on clockwise. At the start of the game each player must pay a small fee, like in poker. After the first round of betting is over then a discarding round starts. The first player discards what he wants using any type of draw card. If he does not have any draw cards to use then he must discard any card he wants and then take a card from the draw pile. He can only discard one card. The add on card (the card in the centre) is now different. He now receives replacements from the draw pile until he has six cards again. Then the next player does the same and so on. Once every player has discarded and the turn is back to the first player then the first full round has passed. Depending on how many rounds the dealer chose to play you must carry on like this until all rounds have passed.
Twos can be used draw cards no matter what the colour is or simply used as a point card (two points), but wiser to swap them for a card from the draw pile. To use just put it on the discard pile and after that any other card you want to discard and then you receive replacements.
Eights will add ten points to any card. Used as a attachment which means it will not count as an extra card in your end hand e.g. any four face cards (ten points each) and a ten attached onto an eight with the add on centre card being 10 will equal 70 points and is a five card hand, not six. The eight does not count. You keep this in your hand if you want to use it. This applies to all other cards that are used as a attachment.
Aces will double your whole hand while in your hand. Used as a attachment (attached to your whole hand).
Face cards are always ten points or you can use them as draw cards.
If you have a five you can put it on the discard pile and take a card from the draw pile and put it on the discard pile face up, making it the new add on card. You have to take another card for yourself after that as a replacement. Or it can be a normal point card worth five points.
Any card that is red will act as a draw card. Put it down and any other card you want to discard and take replacements till you have six cards again. You can do that or use it as a point card worth the number on the card.
Any card that has an odd number on it will be used as a draw card or a normal point card.
[Editor's note: There seems to be a mistake here. In the definitions section it is stated that all even cards are draw cards; here all odd cards are draw cards. I have not yet been able to obtain clarification from the inventor. I suggest choosing one version of the rule - let's agree that even cards are draw cards, but 3's, 7's and 9's are not.]
Jokers can be any of the special cards listed and also used as a attachment. (not counted as a card in your end hand).
To win the game
After all rounds have passed all players reveal their hands. Whoever has the most points in their hand wins. If two players have the same points in their hand then whichever player has the lowest card hand wins. But if you played for a fixed end hand then an extra round is played.
The game is called EnD320 because that is the highest point you can get in a one card hand (320 points) which is four aces, a ten and a eight. The only card that counts is the ten (a one card hand). The ten is attached to the eight which makes the ten a twenty. Then it is doubled four times (the four aces) which all together is 320.
