I used to play on Game Boy, and there was only so far you could get.
I forget what the highest possible level was, but when you reached it, there was an animation of a rocket taking off, and it was the end of the game.
I was very good at Tetris.
I know I've gotten to level 15 on my cell phone version of Tetris. Once you clear 10 lines at that level, it's done. You've done. I've always thought that you just kept going...that there was no real ending.
i got to level 11, but my cousin i know got to level 13 or 14...
I believe it goes somewhere to like level 15, who knows it might very well go to level 20 maybe even 100...haha, that would be like Tetris on Steroids
I've just finished playing Tetris an hour ago, and so far I've only reached the 10th level (I was using the DVD player). It's so hard for me to reach level 11 or more than that because it gets faster and faster.
