A method for operating a multi-cylinder internal combustion engine in which every active cylinder operates in a four-stroke mode and every deactivated cylinder filled with an approximately completed gas filling is compressed and expanded during the four-stroke operation of the activated cylinder. In a method in which excitations of a crankshaft speed are minimized, a limited number of even-numbered cylinders of a multi-cylinder internal combustion engine (2) having a maximum even number of cylinders (20, 21, 22, 23, 24, 25) are deactivated sequentially, the limited even number of cylinders being smaller than the maximum even number of cylinders (20, 21, 22, 23, 24, 25) of the multi-cylinder internal combustion engine (2).
