Bubble Witch 2 Saga Online is a free bubble puzzle game in the tradition of Puzzle Bobble and its descendants. Like other games from Candy Crush Saga creators King, it takes a simple mechanic and dresses it in engaging, colorful character designs. Although the gameplay is nothing new, the controls are simple and effective and the level design is varied enough to keep things fresh. Like other mobile puzzle games, this game pushes its in-app purchases in ways that can often seem frustratingly intrusive.
