Instead of 1 level of 10 cups, there would be 3 levels consisting of: 6 cups on the bottom level, 3 cups on the 2nd. level, and 1 cup on the top level.
Game 1) You can play where you simply land a ball in each cup, and remove that cup regardless of the level the cup is on and drink the contents. Or,
When team 1 is throwing at team 2's Tower, team 1 must land a ball in the cups in the top remaining level, if the ball lands in a cup in the top level, that cup is removed and the defending team (team 2 in this example) must drink the contents of that cup.
If however, team 1 misses the top level cups and instead lands a ball in a lower level cup, team 1 must remove one of their top level cups and drink the contents inside.
Once a team has no more cups left regardles of the way in which the cups were removed, that team losses the game.
