The 55-card edition is designed for up to 4 players and the 84-card edition is designed for up to 6 players. Keep in mind that because the deck will be divided among all the players after the starting word is made, more players means fewer cards in each person's hand., The starting word must have four letters and should be a word that can be made into another 4-letter word by changing one of its letters.Good starting words include "GAME," which can be turned into "FAME," "LAME," "GATE," or "GAZE," and "WARE," which can be changed into "WERE," "WARM," "WARN," or "WART."
Bad starting words include "ECHO" and "EXAM," which cannot readily be turned well-known 4-letter words.
 Place these cards on your table or playing surface where everyone can see them and reach them. Make sure that they are forming the starting word you have chosen. Leave a bit of space between the cards so that the cards you put on top of these cards will not overlap., You may want to shuffle the cards first to make sure that everyone gets a good mixture of letters. Make sure that everyone has the same number of cards when you are done dealing the cards. Remember, all of the cards should be dealt to players; there should be no cards left in the deck., Remind your fellow players that the cards are two-sided. They are printed with a letter on each side, or with a letter on one side and a blank space on the other. Either side of the card may be played to make a legal word, with the blank serving as a "wild letter" as in the Scrabble board game.Get into the habit of looking at the upper left edge of your cards, rather than flipping them back and forth. At the upper left edge you can see the two letters that the card represents.
 The official call to begin play is "Ready, set, slam"; however, you can call "Go," "Start," or something similar, if you wish. Just make it clear to your fellow players that the game is starting.

You cannot play the same letter if it will make the same word. For example, if the current word is "BALE," you cannot play another "B" immediately on top of the "B" in the word. You can, however, play a "G" to change the word to "GALE" and then play a "B" to change the word back to "BALE" if you can do so before another player changes the word to something else.
 to challenge a word. If you don’t think that something one of your fellow players has played is a real word, then you can call for a time out. Then, stop playing to discuss the word's legitimacy and consult a dictionary if necessary. If the word is not a legal Scrabble Slam! word, the player making the word must take back the letter card used to make it., The game is over when one player has no more cards or no more legal plays can be made. At this point, you can declare a winner. If someone gets rid of all of his or her cards first, that player is the winner. If all of the players still have cards and no one can make a play, then whoever has the fewest cards left is the winner.
