Your goal is to align five or more pieces of the same color into horizontal, vertical or diagonal rows. The rows will disappear and your score will increase.
Click on the piece you would like to move, and keep the mouse button pressed down. Drag it to the destination field while still keeping the mouse button pressed. Release the mouse button and watch the piece slide over the board.
You can move game pieces to any field on the board, as long as there is a free path to their destination. Note that you can even let them slide around corners with a single move. Game pieces can be moved vertically and horizontally, but not diagonally.
Apart from the regular marbles, you will encounter many game pieces which add more variety to the game. Build several lines in consecutive turns to get the Combo bonus!
Whenever a new special game piece comes up, you will see a cloud with a question sign beside the board. Be sure to click on it to get some more information about the new game piece.
