Emeraldia

Emeraldia is a puzzle game of the falling-block genre. Cubes fall down, and the player must make vertical stacks. When cubes of the same color are stacked, they will crack. If hit again by another cube of the same color, the cracked cubes will break, and the new one will crack, etc. Unlike similar games, the game does not end when a stack reaches the top. Rather, new cubes will roll over and tumble into empty spaces. Occasionally, a star will fall. A star hitting a block will result in all blocks of that color to be automatically cleared.
