Collatz Countdown
"Collatz Countdown" is an Idle Incremental based on the Collatz Conjecture. You make money by choosing a starting number, and then every few seconds you make the amount of money, that the next Collatz Step is.
The Collatz steps are calculated using this formula:
-If the number is even, it gets divided by 2 (n/2)
-If the number is odd, it gets multiplied by 3, and 1 gets added (3n + 1)
This can cause really unpredictable patterns, e.g. 26 falls into the 4,2,1,4,2,1 loop after 11 steps, while 27 falls after 112 steps.
Have fun!

this is quite polished! could see myself getting addicted if there was a little more (sounds mostly, but more upgrades and even changing things to like 4n+1 or 3n-1 things like that)
I actually wanted to change the rules mid-run, but I did some research and all the other rules I have found either explode to infinity or produce numbers way smaller than the 3n + 1 rule. Thanks for playing!
It's a neat idea, but I think you need to adjust the price escalation on the numbers. Even after you've maxed everything out, that last grind to the end is a real slog.
Also, maybe simplify money and costs down to thousands/millions/billions. When you're dealing with a number like 135312.35, it's a lot easier to parse it written as 135k.
Yeah the prices might be a bit bad for this game. I unfortunatly didn’t have time to playtest this and adjust the pricing. Thanks for playing!
It would be funny if you included a system for detecting a loop other than 4,2,1 with the message of "You disproved the Collatz Conjecture with the number {number}"

if you havent watched it carykh made a really good video called "the collatz multiverse" that covers all of that
Yeah, that's how I did my research. Very cool video
It would be awesome if i could zoom or something, small numbers are hard to see.
