Welltris

The Good
This is a soothing game for my wife, who liked tetris, but got bored. being able to move falling pieces down the 4 sides of the well for the most advantage is a great improvement. occaisionally you will get more than one line at a time. And every once in a while, you can clear a vertical and a horizontal at the same time. While it seems daunting when you first try it, it is actually easier than it looks. I have had times when i cleared a line I didn't see, because I was looking along the other axis. Also, if you get a piece climbing the side, it's not the end. You just can't move on that side for a few turns.

The Bad
There is no way to quit in the middle. you have to make yourself lose in order to quit. Your hand goes numb during a long, high scoring game.

The Bottom Line
If you like tetris, but are bored with its simplicity, take a trip down to the well. You won't regret it.
