GHOST is a computer (solitaire) version of the age-old game in which you try to add a letter without making a word; one and two letter words do not count. If you make a word, you get a letter (the first letter is "G"). When you have all five letters ("GHOST"), you lose.
In this version, you play against the computer. If the computer cannot add a letter without making a word, it takes a letter immediately. You can "challenge" the computer by clicking on the "I Challenge" button. The computer's word will be displayed and you will take a letter. If you catch the computer bluffing, the computer will take a point.
The built-in GHOST word set includes over American English 80,000 words.
Version 2.0.0 lets the user maintain the word set using the Word Maintenance window.
