The bubble puzzle in the Bubble Word Puzzle game will change and become a little more difficult. Each bubble has one or two letter symbols drawn on its side. At the top you will see free square cells. You must fill them in with letters, forming a digestible word. To get a word you must click on the bubbles in the correct sequence. Each level in the game is themed and has nine sublevels. At the first level you have to form a word of three letters and only two balls will appear on the field. At the second level, the number of balls will increase, and therefore the number of free cells that need to be filled in Bubble Word Puzzle will increase.
