"The original puzzle has 8 wedges on a sphere "

"(latitudinal cuts).  There are essentially 3 varieties: "
"Geomaster 8 colors (beachball, default colors in this\n"
"puzzle), Duomaster 2 colors (black and white beachball), "
"and a variety of picture Masterballs.  For some reason,\n"
"they say the Geomaster is easier than the Duomaster.  The "
"picture Masterballs are the hardest since all the pieces\n"
"have a set solved position.  On the Duo and Geo Masterballs "
"pieces could be swapped or in a different order and still\n"
"be in a solved position.  Zurick University's Mathematics "
"faculty has calculated that Masterball's 32 segments can\n"
"be arranged in 355,682,548,566,633,480,192,000,000 different "
"possible combinations.  Masterball was invented by Dr.\n"
"Geza Gyovai Hungarian Engineer, manufactured by Whole "
"Systems Design, Inc..\n"
"\n"
"Related puzzles are the Saturn Puzzle, an oriented Masterball "
"with one band, and the harder Hockey Puck Puzzle, like\n"
"the Saturn Puzzle but with 12 wedges instead of 8."

"ambiguous and the puzzle will not turn.  If there is "
"some ambiguity between a turn or a flip, a flip is\n"
"assumed, except if shift key is used.\n"
"\n"
"Click \"mouse-center\" button, or press \"P\" or \"p\" "
