make for a grand

[KLPNO]

Hello everyone
I'd like to ask about the meaning of the phrase "make for a grand" in the following passage.

Thousands upon thousands islands coalesce into a single body, each island fighting with its stubborn neighbors to remain on the Ocean's surface, basking in the brightest possible sunshine. It makes for a grand, glorious puzzle that would baffle most of you...

What does the phrase "It makes for a grand" mean?

'It all adds up to' a glorious puzzle.......Grand, here, means magnificent. It all adds up to a fantastic puzzle how each island manages to stay separate from its neighbours.
