need advise for no tm challenge

[danielzaiser91]

hi, i am currently doing no tm challenge, and i realized for the first time that ngu number only starts doing something after quite some time into the rebirth.

when is the best time to rebirth to get maximum efficiency of ngu number?
or should i maybe ignore it?

ngu number level for me currently is 823

As with most challenges, your best bet is to wait until your stats are high enough to be doing 3 or 5 minutes rebirths while getting a lot of progress.

You can of course do them earlier if you need the bonus it gives but usually you do this (and most other challenges) around Walderp.

Among what helps are wandoos (preferably 98 because you are still in the "bootup" that early in a rebirth) and augments.
Augments might seem counter-intuitive in a no time machine challenge but you can still get gold from adventure mode and use it to get the first or second augment up and running quickly.
If you are after UUG, beards can end up getting you a noticeable boost.

If you are doing the challenge earlier than that, yggdrasil's fruit of power alpha (and beta if you have it) can make a difference as well but you need to wait a full hour for their growth.

The bonus from ngu number is multiplied by the current rebirth time factor shown on the rebirth screen. This makes it better to rebirth at the same times as the rebirth time factor jumps: https://ngu-idle.fandom.com/wiki/Rebirths#Rebirth_Numbers

So 3, 4, 5, 7, 10, 12, 15, 30, 60 minute rebirths, which you should be doing anyway during challenges.
