Polarium is a puzzle game for the Nintendo DS that challenges players to flip black and white tiles to create and clear solid rows of a single color. It employs the handheld's touchscreen for stylus-based gameplay, allowing players to draw lines to flip the tiles. Polarium includes a Puzzle Mode where players solve preset puzzles, and a Challenge Mode which involves creating and clearing lines of tiles before they reach the top of the screen. Its minimalist aesthetic, accompanied by simple yet addictive mechanics, makes it a distinct entry in the puzzle genre for the portable system.
