Mario Paint is a unique addition to Nintendo Switch Online. On the surface, Mario Paint is a simple drawing program, something like a minimalist, Nintendo-branded version of Photoshop. That’s already an interesting enough idea for an SNES game, but Mario Paint goes so much further in enabling your creativity. Some of the most interesting parts of Mario Paint have nothing to do with painting at all. In this part of the game, you can arrange a set of Nintendo stamps, each representing a different sound effect.
