There’s no shortage of games where you have to match blocks in order to make them vanish. What Match 3D brings to the table is that the playing field is an 8x8x8 cube which you can rotate on any axis by flicking. You make the blocks disappear by matching three or more side-by-side (diagonal doesn’t count), so you’ll have to quickly learn to think in three dimensions.

A hundred years from now, I’m sure there will be a series of academic papers, thick as a phone book, about the obsession in the early 20th century with making crystals disappear in games. Was it a protest against rampant materialism? An attempt to deal with the psychic fallout of the blood diamond conflicts? But future academics will probably not hit on the real reason: shiny thing go bleep!
