WHAT IS TETRIS? WHAT IS DR. MARIO?

Tetris is a game that challenges your skills in quick judgment and reaction.

The game is very simple and quite easy to understand. On the screen, there are seven different shaped blocks that will appear and fall down one after the other. You will need to move them, turn then and pile them up without leaving spaces between them. Complete a row or "line" without any spaces and it will disappear, scoring you points. When your pile of blocks reaches the top, the game is over.

There are three ways to enjoy playing this game: The first, A-Type, is a challenge of endurance. The second, B-Type, requires you only to clear 25 lines. Your third option is to challenge a friend or the computer in a head-to-head match.

Dr. Mario is an action puzzle game in which you must exterminate all the Viruses that have infested the bottle on the screen. The Viruses come in three colors and they can be eliminated by aligning the like colored vitamin capsules that are falling into the bottle.

The basic rules of Dr. Mario are easy to understand. Simply line up at least four Viruses or vitamin capsules of the same color either horizontally or vertically. Do this and that color group will disappear. As the capsules appear on the screen, one at a time, move and rotate them to exterminate all the Viruses in the bottle. When is done, the stage has been cleared and you can move to the next round. However, should you allow the capsules to pile up to the top and no other capsules can drop inside, the game is over. Your goal in the 1PLAYER GAME is to try to clear the highest level you can. While playing the 2PLAYER GAME your basic goal is still to exterminate all the Viruses in your bottle, but you must do so before your opponent does. Along the way you might even find it more fun to interfere with your rival's game. You can even attempt to win by making him lose. Have fun and enjoy Dr. Mario!
