How do you get to all of the worlds on mariobros?

For the worlds that branch off to two worlds (One with solid line one with dotted line) if you beat it normally you get to the world connected by a solid line. If you want to get to the world connected by the dotted line, you have to beat the final level as Mini-Mario.

It's kinda hard since you gotta beat the second and fifth worlds with mini mario/ luigi then youll chase off bowser jr. but youll end up falling through the tiny hole (since you're mini) and the sign that reads world 3 will change to world 4 and the one that reads world 5 willchange to world 7.

1: u gotta get through all the levels in that world

2:u mus get to the last and biggest castle at the end of that world

3:do above 2 worlds 1,2,3,5,6,8

4:to get to world 4, bring a mini mush into world 2 and be mini mario and beat the boss of world 2 in mini form
