9. Bejeweled Blitz
Made by PopCap games, Bejeweled Blitz is the facebook adaptation to the popular Bejeweled franchise. The game plays similarly to the other Bejeweled games except in this version you have to race against the clock to match gems and beat your score. Although, you can get more time if you match three or more of the same gems, unique gems can be made by matching pairs of four or more, these gems have varying special effects which are quite beneficial to you.
Putting four or more gems together creates a flame gem which will destroy the gems around it when lined up with two more flame gems. A T shape created by gems will give you the star gem which send a bolt horizontally and vertically destroying all gems in the way. A hypercube can be formed when you put together five gems in a row or column. If you click on the hypercube and click on a gem adjacent (up, right, left, down) to said hypercube, it will destroy that gem and all gems like it on the board. The last special gem is the supernova which can be created when aligning six gems. It destroys most of the gems on the board which can also cause a chain reaction. Boom!
