4 new NES and SNES Nintendo Switch games will be added to Nintendo Switch Online next week, Nintendo has announced.

The steady flow of new titles being added to the Nintendo Switch Online collection stopped upon the announcement of SNES gaming being added to the library. Prior to the announcement, Nintendo added new NES games on a monthly basis, but this is no longer the case.
