Thunderbolt: "Blitz mode is where times comes into play. In five minutes, as many points as possible need to be nabbed. Some bombs still make an appearance, but the game switches from something methodical to a mad dash. This brilliant change of pace makes playing in quick bursts an easy endeavor. Another quality way to play are with challenges. A bit less frenzied than the blitz mode, the 13 different challenges each have six increasingly difficult levels. The tasks include destroying a certain amount of gems in one move, consecutively eliminating a number of rows without one bad move, and so on. Some of these are hard. Really hard. Still, at least there are a ridiculous amount of challenges to keep the hardcore busy."
