This one is called Off the Grid and you can get it at: https://market.android.com/details?id=air.grid&feature=search_result or just search the market for 'off the grid'.
In this game, you are presented with four puzzle pieces at a time, which you have to drag into place before the timer runs out. When you line up four pieces, they explode. It's just a slightly different take on the classic block game; I thought the drag mechanic would work well on Android.
