In Marble Legend you have a cannon placed on field with a track winding around the field ending at a basin. A line of colorful marbles rolls down the track and if it reaches the basin, you have lost. The player controls the cannon in the middle and shoots balls at the slowly moving marbles. When three or more balls of one color are one after another, the balls disappear. When a gap occurs between the marbles, its possible to draw both parts together by shooting balls of the same color to both sides of the gap.
Some of the moving marbles can transmute into power-up marbles which can e.g. slow-down the moving speed of the marbles or make them even move backwards. Marble Legend has an adventure mode and a challenge mode. The game is free, but has in-game advertisments.
Marble Legend was developed and published by easygame7 for Android in 2013.
