Patricia Frederick’s Tips for Candy Crush Level 482
Break the blocks in the center column (avoiding the top block as long as possible to delay releasing the bombs.) Once that block is broken, use the bombs to make as many specials as you can to achieve collecting the blues and purples as quickly as you can. Do not break the blocks at the tops of the outermost columns or you will have your hands full of bombs.
