Klickety is a kind of solitary game that takes place on a Tetris-like board. This game is also known under the name "clickomania"
Once the game starts you will be presented with a board filled with multicolored marbles. You can erase some of them as long as they are of the same color and are aligned either vertically or horizontally. If there are pieces of other color located over the erased marbles, they will drop down. In the same manner, all the marbles located on the right from the erased ones will shift to the left. You are expected to clear as much of the game board area as possible.
