Relax game Marble Zen with puzzle elements will allow you to relax and think a little. You will manipulate white and black marble balls. The task is to use a black ball to remove all white spheres from the field. Use the arrows to make the ball move and hit the ball that is on the line of impact. The white ball will fly off the field, and the black one will take its place. This way you can expel all the white balls. If there is no white ball on the path of the black ball, it will fly off the field and the level will fail in Marble Zen.
