The tool for completing levels in the game Mag Roller will be a medium-sized ball. His specialty is that he can attract objects that he comes close to. To complete the level you need to destroy buildings and objects by rolling a magnetic ball over them. In this case, the site should be empty. Roll the ball, first destroying the structure and then collecting all the debris. In this case, the ball will increase in diameter due to objects stuck to it in the Mag Roller. With each new level, objects to be destroyed will increase in size.
