PopCap Games, the casual gaming behemoth that has given us such addictive mega-hits as Peggle and Plants vs Zombies, has gone on and released one of its older games for them iOS devices. Apparently, one of the company's programmers loved Candy Train so much that simply had to come up with a version for iOS. In her very own free time. The game, a lovely, colorful, action puzzler is now available for free. Where? There.
