Polarium Advance
Game modes. Unlike its predecessor, "Polarium Advance" was released for the Game Boy Advance, with some significant changes. The unpopular Challenge Mode was removed, and the game focuses more on the Puzzle Mode, which features 365 puzzles - nearly four times as many as "Polarium." Each puzzle stage can be played in Stage Mode, with no time limit, or Time Mode, where the player aims to complete a puzzle as fast as possible. Edit Mode for creating custom puzzles makes a return in "Polarium Advance" as well. The color scheme is changeable from black and white, to add a  bit of customization and color to the game. How to play. As in the predecessor, the goal is to select tiles by drawing a line over them with one, continuous stroke. "Polarium Advance" uses the D-pad for controlling where "Polarium" used the DS stylus, and the A button (or L, for playing single-handed) for starting or ending a stroke. Selected tiles will flip from black to white or vice versa, and the puzzle is completed if each horizontal line consists of a single color afterwards. Surrounding the main puzzle area are gray "neutral" tiles that have no effect  on the puzzle but can be used to flip disconnected groups of tiles in a single pass. Special Tiles. In order to add some variety to the gameplay, three new tiles have been added in addition to the standard black and white ones. "Solid tiles" cause all tiles above them to fall when erased, "Hurdle tiles" cannot have lines drawn over them, and "Multi-tiles" are "wild cards" in that they function as white or black panels. Reception. The game received "average" reviews according to the review aggregation website Metacritic. In Japan, "Famitsu" gave it a score of three  sevens and one eight for a total of 29 out of 40.
