I started playing Sparkle when it was first released and I loved it, spending most of my internet time trying to get the game completed. 8-9 years on and I'm still playing it with the end nowhere in sight. At the same time I have been playing Zuma and other popular ball shooting games, always preferring to play Sparkle over the others in this genre. However, lately I have found it somewhat more difficult as I feel the developers have tweaked it up by offering only single colour balls making it far too tedious, still my fave tho.
