Sky Kingdom is a marble popper game with a bit of an arcade feel. The goal of the game is to clear the marbles from the board by matching three or more of the same color marbles. Players match the marbles by shooting them onto the board and attempting to get the marble in the correct line of marbles on the board. Players have three lives and each time they lose, i.e. the marbles on the board are not cleared in time, they lose a life. Even though there are only three lives, the game doesn't end if you lose those lives. The last level to be completed is saved and players can start again at the saved level in the game. Players do not have to redo all of the previously completed levels.
