Whats the difference between the Shareware version and the Registered Version?
ALL settings in the Registered Version are saved (colors, play options, rule options, etc.) as opposed to just some of them in the Shareware Version. All the options are available, but you have to set them each time in the Shareware Version. The other difference is the countdown timer on the closing screen. The Shareware Version has a countdown timer that must get to zero before you can exit the program. With Registered Version, you can exit immediately upon the closing screen being shown.
