There are a few issues here:

   1) There is already a game called Puyo Puyo. For copyright reasons, you
might have to name your game something else.
   2) If by "Java console", you mean the text-only console that is hooked
into System.out and System.in, I think Java's console support has too little
features to make a game similar to Tetris. Have you considered making your
game with a GUI using Swing?
   3) Programing games is difficult. It's not nescessarily the most
difficult domain of programing, but it's far from being the easiest. If you
are a beginner in Java, I recommend you start with something simpler than
games. You said you are a beginner, but we don't know how much you know.
Have you ever written a Java app that has a GUI? Have you written a
(possibly text-only) Java app that does file I/O? Have you written Hello
World in Java?

Animation is a great motivator but you need some basics first.  I
would tackle a project with some simple static drawing first, e.g.
using a Canvas and draw methods. Have at look at the code for
