Rules:
      Jezzball is based on the game by the same name originally written by
	  Dima Pavlovsky and released in the Microsoft Entertainment Pack for
	  Windows 95. You advance through increasingly-challenging levels, filling
	  the playfield by placing walls. You must prevent atoms (balls) from
	  touching walls that are in the process of being built, but once a wall is
	  complete, the atoms will bounce off that wall. Your goal is to fill at
	  least 65% of each level to proceed to the next level. If you fill more
	  than 65%, you receive a fill bonus proportional to how much above 65% you
	  filled the play field. If you beat a level quickly, you also receive a
	  time bonus. Your goal is to advance as far as possible.
	  
	  Jezzball v1.0 for the TI-83 Plus/TI-84 Plus has nearly identical rules to
	  the original PC game, with a few tweaks to make it more fun on calculators.
	  First, the fill algorithm works slightly differently. The calculator
	  version will only fill areas perpendicular to a new wall drawn, while the
	  PC version will perform a flood fill. The calculator's grid is also smaller
	  than the PC's grid, to fit the smaller screen. Finally, the computer
	  version sets the threshold to advance to the next level at 80%, whereas
	  this version requires a minimum fill of 65%.
