Today's Free App of the Day is Collapse! Holiday
This is a nice rising-blocks game--you need to eliminate blocks in groups of three or more by color before it reaches the top. There's a nice little Christmas theme and there's a quest mode. It plays in portrait mode, appropriately enough for this kind of game and will rotate 180 degrees.
Nice game, nice little Christmas theme. I'm not sure I'd want to play it on a device smaller than a 6 or 7 inch tablet. Four stars from me.
8 of 10 reviews are four stars and above.
