In the rule “Forbidden Island Local Rules”, add the following to the first paragraph:

Each Meeple has a publicly-tracked list named Map, which contains any number of “Turquoise”, “Magenta”, or “Purple”, and defaults to an empty list. There is a publicly-tracked list named Path, which contains any number of “Turquoise”, “Magenta”, or “Purple”, and defaults to an empty list.

In the same rule, append the following text:

Whenever a square’s color is changed from White to either Turquoise, Magenta, or Purple, add the name of that color to the end of the Path.

A Meeple is Worthy of the Forbidden Island Gate if their Map matches any contiguous sequence of at least three colors (not required to be unique) of any part of the Path, in the same order as they appear in that part of the Path.

In the rule “The Turn”, add the following as sub-bullets of the bullet “Phase 2”:

* (Forbidden Island) [5] Once per Token you control on Forbidden Island per Turn, if that Token is on a black square and does not have a Status of Lost, you may move that Token to any red square on Forbidden Island.
* (Forbidden Island) [5] Once per Token you control on Forbidden Island per Turn, if that Token is on a red square and does not have a Status of Lost, you may move that Token to any black square on Forbidden Island.
* (Forbidden Island) [7] If your most recently moved Token is in Forbidden Island, and if that Token is on a turquoise, magenta, or purple square, you may add the color of that square to the end of your Map’s list.

In the same rule, add the following as sub-bullets of the bullet “Phase 3”:

* (Forbidden Island) [5 for Big Tokens, 7 for Medium Tokens, 9 for Small Tokens] Once per Token you control on Forbidden Island per Turn, if that Token occupies a square with another Meeple’s Token, add a color from that Meeple’s Map to any position in your Map’s list.
