Blockers are the items in Bubble Witch 3 Saga which prevent a player from reaching other bubbles. They can be destroyed - some easier, some harder.
There are many different kinds of blocker bubbles. Each has different properties, and has to be dealt with differently, in order to proceed in the game.
