To all my fellow island tycooners, make sure you aren't skipping out on your rebirths by leaving them unclaimed after a long session of grinding. Once you've gotten the holy nugget, all you need is 1.5m cash and 2.5m gems to unlock the rebirth button, and hitting 4 rebirths allows you to unlock the gem boost that eliminates that long annoying grind for the second floor dropper. Once you have the boosts you can get to the third floor nugget in just a couple minutes and bypass literally 90% of the progression.

Best to do it in a private session since only the player in the middle lot (the one it automatically puts you in when you start the map solo) can activate the boosts because the map is programmed like garbage. If you're planning on grinding for a while, claim a rebirth and switch to the lot on the right, since it gives better payouts. Best of luck and happy grinding.
