Brain Buster Puzzle Pak features hundreds of puzzles ranging from the
hugely popular Sudoku to the latest craze in Japan, Kakuro. Also
included are the uniquely challenging and innovative games Light Up,
Nurikabe, and Slitherlink. These puzzles have all been created in
conjunction with Nikoli, the leading puzzle creators in Japan. Along
with the straightforward puzzles in Brain Buster Puzzle Pak, there are
added bonuses that can be unlocked as players enjoy solving the mind
benders. For example, various monsters and asteroids distract you as you
work on puzzle, but by removing them you earn special hints, adding to
the fun factor. Wallpapers also become available after completing
certain puzzle problems which can then be used to change the background
graphic of each game.
