Notes:

Technically, it's not the same kind of "Mario Bros", and might just be a different genre altogether. But it's Mario Bros. so I am technically correct, the best kind of correct.
From this twitter post. Apparently there are even more ways to play Mario Bros. than what's been listed in this image I posted, according to the comments section.

There are now five different ways to play this on the switch (technically seven if you count the arcade and NES versions) pic.twitter.com/1fwfmlUMWv
