The basic game mode, Egg Mania, is almost like a reverse Tetris
. Instead of completing rows of blocks in order to keep the column clear, you stack blocks up, using an egg shaped character to create a tower of blocks. Once the tower reaches the top of the column, the level is cleared. In addition to the usual rotating blocks or placing them, you can also throw them away. This unusual but useful feature allows you to streamline game play, but at the cost of added time. Almost all modes involve competitive play, either against another person or a computer opponent, so the first player to reach the top is the winner.
In Tetris, gaps between blocks keep the player from being able to easily clear the entire column, but gaps in EGG do not hinder the game in the same way. Since the bottom of the column is comprised of water, gaps let the water make its way up the tower, and can cause the rows with gaps to be destroyed. This, in turn, will impede the egg's progress, and waste precious time. To fill the gaps, you can make your egg character jump off the tower and place blocks in them, which offers an interesting twist on game play, but again, costs time as you have to wait for the egg character to make its way back up the tower.
A number of Trick Bricks fall or can be tossed into your column by your opponent. Some allow the egg character to jump higher or they automatically fills in gaps, while others can be thrown into your opponent's column, and can stun him or destroy some of his blocks.
In addition to the basic game mode, there are others, including one where your goal is to bomb your opponent's tower, a less exciting Solo mode, and the never ending Survival mode. In addition, EGG offers the awesome Custom mode, which lets you tailor the game play to your liking.
