Push Square: "The aim of Sparkle is to fling different coloured marbles at a procession of similarly styled balls that are rolling progressively closer to the centre of an on-screen maze. Put three of the same tinted spheres in a row and they will detonate, with your ultimate goal being to spontaneously combust all of the orbs as promptly as possible. You can launch globes using the right stick or touch-screen, but we often found that the latter proved a more accurate method. Interestingly, while many marble poppers work on a top-to-bottom basis, this game goes the other way, forcing you to destroy the shiny widgets as they follow snake-like routes to the middle of a maze. It's a lot like Zuma, then."
