Rock-It Blast is a limited Rare Gem in Bejeweled Blitz. It is a blue gemstone that resembles a firework rocket. This Rare Gem was created as a way to celebrate the Fourth of July. When the player begins a game with Rock-It Blast activated, one of three special starting layouts appears. All three configurations include unique blue gems that resemble firework rockets. A rocket functions identically to a Flame Gem, except a rocket clears 24 gems in a 7×7 checkered pattern instead. The base value for clearing a rocket is 1,000 points. While Rock-It Blast is active, rockets replace random blue gems throughout the game, and Flame Gems created using blue gems become rockets instead.
