With the basic modes (endless, time trial, puzzle), you've got the coup de grace, the heart & soul, the very mode this game was named for, Versus. As Yoshi, you must save the world from Bowser... big surprise... and you must persuade many characters along the way to aid you in your quest. Persuasion tactic of choice? Dropping hunks of stone on them by performing chains.
Refreshing addition to the Tetris repertoire and, imo, much more fun to play. Easy and addicitve for all ages.
