Planet Delta: A Journey to the Core

During its travel through space, a flying saucer runs out of fuel. Fortunately a meteor with a power source is in flying reach and the crew starts to search for the materials needed to create more fuel. The search will last through about 40 levels in four environments (e.g. space, jungle and planet core) which only effect the background image.

Planet Delta: A Journey to the Core is a match-three game. There are a number of differently colored balls in a tube and the player's goal is to remove all of them by throwing additional balls into it. When three or more balls of the same color touch, they disappear and give points to the high-score (a chain reaction reward even more points). However, when the additional ball does not score, the bottom of the tube may rise - when the balls reach the top, the game is over. The ball is thrown by holding down the action button; how long it is pressed changes where it lands. There is a preview of said location as well as for the next ball in line. Sometimes there are other elements in the tube, for example stones (break when hit) or bombs (explodes when hit and takes all surrounding elements around it out).

Besides the story, there is also an arcade mode and a practice mode available.
