New way to play, for anyone looking for a twist.
Set to three lives. Stars don't matter. Go to the Ice Level. Left of the starting pipes are some bricks and some gaps.
Both players run over to this area - one play starts on the left of the main gap, one player starts on the right. Both players bow to show they are ready. Now, you aren't supposed to leave the icy area (although you may occasionally get knocked away). The idea is to knock your opponent down one of the holes. When one player falls and respawns, they rush back over, both players bow again, and the fun starts anew.
For an added twist, have one player grab the mushroom/turtle shell and knock some of the bricks away in various patterns.
