Each card has a different letter tile on it. The distribution of letters matches the distribution of letters in normal English usage. One of the tiles has an asterisk on it, which is a wildcard, representing any letter.
Here's my suggestion of how to play. To begin with, deal each player (up to four players) seven cards. The aim of the game is to score the most points. Each turn a player may either draw another card, or may play a word. Points are scored based on the length of the word, as shown in the table below. If a player uses all their cards in a word, they can draw seven more cards. When there are no more cards, and no players can (or want to) make a further word, the game ends and the scores are totalled.
|Number of letters in word||Score|
|each additional letter||+50|
Valid words are those in whatever dictionary is to hand. Proper nouns are not allowed, but pluralizations and modifications to other parts of speech are allowed, as long as the dictionary explicitly gives them.
I'm a big fan of word games, and I love Scrabble. The tiles on dicecards aren't intended to play Scrabble with. For a start they don't have points values on them, secondly there are only 54 of them, rather than 100. I've been asked several times to add scrabble scoring to the tiles on the cards, but the combination of letter and score is proprietary to Hasbro, who own the Scrabble brand. And unlike the Small World and Heroscape dice on the cards, the tiles aren't just used to play Scrabble, they are, in a real sense Scrabble, so duplicating them isn't appropriate. The smaller number of tiles makes the scores irrelevant, in any case, since the distribution of scores would be so different.
