Magnetica

In the game, marbles roll down a twisted path toward the goal and the player must stop them by launching new marbles into the oncoming ones. The DS touchscreen is used to 'flick' the marbles from their launch point to their destination with the stylus. The marbles disappear if player matches three or more marbles of the same type; marbles of the same color are magnetically attracted to each other over any length of wide open space, and allowing for chains of disappearances to occur.

The game is over if any marble reaches a specific point, usually near the center of each level, but using the magnetic properties of the marbles can allow one to pull marbles away from this point. Bonus items attached to marbles can, for example, temporarily slow down the rate the marbles advance or cause all marbles of a color to disappear.

Magnetica and Magnetica Twist received "average" reviews according to the review aggregation website Metacritic. Nintendo Life said that although the DS version fails to impress with its visuals and audio, it is an excellent addition to anyone's Nintendo DS library whether a gamer is casual or hardcore. The Washington Post criticized the same console version's $35 price tag, which it said was a bit too much for a game that has nothing new to add. In Japan, Famitsu gave the same DS version a score of three eights and one seven for a total of 31 out of 40.
