This might sound easy; it's not. You have to line up five of the same symbols in order to get the line to disappear. Every time you move a symbol, more of them will pop up. To move the symbols, tap on them with your sylus. Then tap where you want them to go.
The object is to get rid of all the symbols on the board. Think you can do it? Good luck!
