User Rating: 8.9 | Lumines: Oto to Hikari no Denshoku Puzzle PSP
This game is all flash and all substance. This game is highly addictive with it's puzzling gameplay and amazing sound. This is a great game for the PSP and I recommend making this one of the first games you get for your PSP.

Lumines is a puzzle game where you connect 4 or more of the same color blocks to keep for touching the top of the screen. Similar to Tetris but has great sound and tons of value to this game. By value you can unlock tons of stages and characters for your profile.

This games as several modes of play. Challenge Mode where you go on one maps and play through and though while the map changes and music. The farther you play the more you unlock. Then there is VS cpu, or VS 2P. In battle mode you can do well and make your opponents area smaller so it's harder for them to place pieces.

If your into puzzle games or want some addicting game to take on a trip; this is the game you're looking far.
