icon A Picross-type game featuring puzzles originating in print form and dating back to the 1980s, developed with Fenix for GP32 in 2004, and now adapted for Dreamcast.

The objective of the game is to complete each puzzle within a time limit, you will need to select blocks which should be filled, and leave the remaining blocks empty to solve the puzzle and reveal the hidden pattern. Clues for every puzzle are shown across the top and down the left side of each playing field, the clues reveal the amount of blocks that need to be selected and filled within each line, and a series of numbers within each clue reveal that there are empty spaces required between the filled blocks.

Logic GP was developed with Fenix for the GP32 by KeKo. There are two options from the menu: Easy Level which features a 10x10 block playing field, and Difficult Level which features a 15x15 block playing field. A visible timer counts down during each puzzle, and a time penalty will be given if you select a wrong block during play, when the timer runs down it's game over.

This release comprises of Logic GP along with DCEvolution's version of Chui's Fenix SDL Loader (FSL) from November 2004, edited to exclude the Fenix splash screen and jingle, so the game loads directly.

The text within the game has been translated to English, the graphic files containing text have also been edited (using the same font) for English. The controls for the game have been edited to avoid inadvertently resetting the Dreamcast during play, and the WAV sound effects have been balanced for volume. Due to the alterations for this release, a download for the original GP32 version has been made available.
