I bought the original Major Magnet game and love it, so thought I'd recommend the sequel Manic Marvin: Arcade as it's just as good. It's free-to-play (and should be the golden standard of those games 
), and you can pay to get rid of the ads. The "currency" itself is easily earned by just playing the games.
It's for both iPhone/iPod Touch and the iPad (requires iOS 7). They recently released a fix for performance issues on A5 devices.
