Here's the sequel to the brilliant sleeper hit puzzle game on the PSP. The premise is simple: line up same-coloured blocks in square shapes of four or more and link them together. A beam travels across the screen, wiping out any of these linked blocks so the trick is to get as many combos going before they are swept away. This time around the backgrounds are made up of music videos from the likes of Black Eyed Peas, Gwen Stefani and Chemical Brothers. This can be very distracting! Multi-player, a shape creating puzzle mode and Time-Attack are excellent for short bursts of play. If there is one criticism it's that there are few changes from the original game. Still, it's the best PSP puzzler by far.
