This is simply a sophisticated version of Hangman, except that instead of getting hung you lose points.
The computer makes up a simple crossword of up to five different words. You're shown the shape of the crossword, and the letters which need to be fitted into it. You start at any position on the crossword and guess the letter.
If you're wrong you lose points, but when you get it right it helps you to make a better guess at the next letter.
The program comes with 5000 words (which on the 16K version can only be loaded 600 at a time). You can choose how many words you want in your crossword and one of three different
skill levels according to how difficult you want the words to be.
But the game would've been a lot more interesting if the crosswords were a little more intricate. It's hard to see Xanagrams being played a lot.
