I own this game on the nes, it's no different than the other tetris games.
However, there is one twist. If you are about to lose, and you have the bottom
half of a yoshi egg, don't put anything else in that column exept the top half
of the egg. This trick will get rid of any blocks inbetween. Note: you must have
at least one space left, other wise you'll lose anyway.
