PLAYING THE GAME
Shuffle the cards together, deal 13 cards into a pile, and put the rest to one side. The first player starts by taking the bomb and the die. Roll the die --- this decides whereabouts in the word the letters may be used.

If the die roll is TICK : letters may not be used at the START of the word.
If the die roll is TICK...TACK : letters may be used ANYWHERE in the word.
If the die roll is just the picture of the BOMB : letters may not be used at the END of the word.

Now start the bomb, and quickly turn over the top card from the pile of 13. These are the letters that must be used until the bomb explodes. As soon as you have said a word which includes the letters, pass the bomb on to the player on your left. Play continues in this manner until the bomb goes off. Whoever has the bomb at that time is given the card that has been used as a penalty, and starts the next round by rolling the die, starting the bomb, and turning over the next card.

The game continues until all 13 cards have been used. The winner is the player holding the LEAST number of cards. If there is a tie, the players involved continue to play on a SUDDEN DEATH basis, drawing one card at a time from the top of the unused pile until a clear winner is found.

PERMITTED WORDS
Any word in common usage is allowed, including proper names, brand names, colloquial words, and also foreign words in general use --- e.g. blitzkrieg, arpeggio, denouement, kibbutz, etc.

A word may NOT be used twice in the same round, but may be used in a subsequent round. For a more challenging game, do not allow simple derivatives to be used --- e.g. if Play has been used, do not allow Plays, Played, Player and Playing. But words like Display, Replay, Foreplay would be OK.

The letters printed on the cards MUST be used in the EXACT sequence as part of a larger word --- e.g. Ant can be used in Pant, Scanty or Antelope. It cannot be used on its own, or broken up as in Aunt, Quaint or Adventure.

FINALLY
A player's turn is finished as soon as he or she has said an acceptable word, and passed the bomb on, even if the next player has not yet taken hold of the bomb.

Any player may challenge a word that has just been said as not being acceptable. The player holding the bomb can then pass it back to the previous player to try again. If there is an argument about whether it is a proper word, ALL players vote. If the bomb goes off before the decision is made, and the word is accepted, the player who has passed the bomb back loses. If the word is not accepted, the player who said the word loses.

When a challenge is made, the player who has passed the bomb does not have to pass it back, but may prefer to say a word and pass the bomb on, rather than run the risk of a challenge being overruled and the bomb going off.
