Excerpt: I found Ultimate Block Party for an extremely low price, and we need something on the Playstation Portable (PSP) for the review section. I also researched this puzzle game, and found a lot of other places seemed to like this hand held game. The puzzle game has the player rotating four small blocks at a time. Get four (or more) of the same color touching one another, and they will disintegrate. The bottom keeps marching up towards the top.
