FIVE

This is a mod of Alex Fink's Dive. Tiles refuse to merge if the result isn't 5-smooth.

Try again

When you make a new tile N, the game divides N by all current seeds, and the result is "unlocked" as a new seed if it is not 1. These new seeds aren't actually always prime! (Can you get a composite one?)

The basic lore of Threes variants, of which there are many (three cheers to github!), is well known by now: the deluge was opened by 2048, created by Gabriele Cirulli, based on 1024 by Veewo Studio which in turn was conceptually similar to Threes by Asher Vollmer.

The basic idea of this variant was due to Allen Knutson, with design contributions also from myself and Vynce Montgomery. It was first implemented as DIV by TheMoreYouKnow; this version is a fork of theirs.

The name "Five" is a play on the name of the original game, and on the fact that all numbers here are 5-smooth.
