Magnetica is a puzzle game for Nintendo DS in which players use the stylus to launch marbles onto a moving track. The aim is to match three or more marbles of the same colour before the line reaches the end of the path. The game features single-player modes, including Challenge, Quest, and Puzzle, with different tracks, power-ups, hazards, and stage layouts. It also includes head-to-head multiplayer, where players can use items that obstruct, deflect or alter the movement of launched marbles.
