Lumines Plus

Lumines: Puzzle Fusion is a falling block puzzle game. The objective is to arrange grouped blocks descending from the top of a 16×10 grid playing field to create single-color squares once they have landed. Grouped blocks have a 2×2 shape and vary between two colors. Players can rotate the descending grouped blocks, move them left or right, or drop them straight down.

When part of the grouped blocks hits an obstruction, the remaining blocks separate from the rest and continue to fall. A single-color square is created when grouped blocks form a 2×2 shape of matching color. Additional blocks of matching color can be used to create larger shapes. The game ends when the blocks pile up to the top of the playing field.

Lumines: Puzzle Fusion was the first game developed by Q Entertainment with Tetsuya Mizuguchi as the designer. Mizuguchi was part of the studio's founding following his departure from Sega after they dissolved United Game Artists, Mizuguchi's previous venture. It was developed by six people in a year. The game was 75% complete when it was announced at the Tokyo Game Show 2004.

When he first learned about the PlayStation Portable (PSP), Mizuguchi was inspired to make a puzzle game with music for the device, which he described as an "interactive Walkman". He considered it ideal for his game because it was one of the few handheld consoles to have a headphone jack and high-quality sound. To attract casual players, Mizuguchi wanted his new game to be less daunting to play than his earlier titles Rez and Space Channel 5. Originally, he wanted to make a music-heavy Tetris-style game but problems with licensing led him to create a new concept.

Lumines: Puzzle Fusion received "generally favorable" reviews, according to review aggregator website Metacritic. Multiple reviewers praised its combination of music and visuals. GamePro complimented the combination of music and colors, calling it "a mini rave in your hands". GameSpot praised the way the game's sound and visuals correspond to the actions performed.

PALGN commended the game's graphic design, saying the menu design and avatars make it distinct. Although PALGN's reviewer did not enjoy the game's music genre, the website still gave a positive review to its soundtrack. Eurogamer deemed the audio superior to the visuals, praising the way the player's actions build the musical elements to a crescendo, and described it as "the real star of the show". IGN provided a more critical assessment, saying the sound and visuals do not have enough interactivity to allow players to feel an impact.
