Fun word game! At the START/OPTION prompt, insert the second side of the disk (which contains the word "cards"). When requested for a card, type a THREE DIGIT number (eg. 003). I don't know how high you can go.
Each card contains a category of words. The category is listed above the rectangles in the upper-right, and each rectangle displays the first letter of one of the words in the category. Below the rectangles is a total of all the letters in all the words (though each time you play the card, different words are chosen).
Type in a word to guess it, or press ENTER if you're stuck (which displays one of the words). You have five chances. There is also a "bonus round" which is timed and involves anagrams.
Lots of play options to choose from, and I don't understand the scoring, but still fun!
