Fast donut farming

KEMs are more efficient but take longer.

I'm over the 939 mark. Is it better to only open one box or to spend the money to open another box for more donuts? Or is the 50,000 more efficiently spend on more KEM.

Not really, if you do the math, lvl is mostly unimportant, you'd need a multiplier of 3400 or so to make the difference. It averages out to $50k per bonus. You lose a lot of you're giving up those donuts.

My multiplier is 515% + 154%. I open the $50K boxes until I find 3 donuts and the $150K boxes until I find 2 donuts.

My multiplier is 314 plus 154. So I guess it's better to only open a second 50k box if I have one donut. Better to save the money for more KEM s.

I think it should be the other way around - the lower your multiplier, the more willing you should be to pay for opening extra boxes in the hope of finding more bonuts. This is because the cost of triggering the game goes down as your multiplier goes up... e.g. at level 939 with the XP collider running it costs me approximately $300,000 in truck purchases to play one round of bonuts, but would cost more with a lower multiplier.

Spam is correct. Open 100 boxes and on average you'll spend an extra 50k per box to get 3. Unless your multiplier is high enough to turn that $50k into another bonus box, you're better getting the 3.

Someone did a post a few months ago that did the math on this.

There definitely comes a point where it makes sense to not always pay for 3 donuts. For example, if you hit 2 donuts on the first try, maybe you pay $50,000 and get 3. But you might pay $100,000. So that extra donut really costs $75,000 on average. It depends on your multiplier, but there definitely comes a point where that's not a good idea any more. I need to buy just over 10 KEMs for a donut box. Once you account for selling back the KEMs, that comes out to about $110,000 per box, or $55,000 per donut (more or less...technically my dollars per donut is much harder to calculate than that). So, it makes sense for me not to spend $75,000 on the donut.

Now, if I hit one donut on the first try, it still makes sense for me to pay, but I will soon be at a point where it won't make sense to pay if I hit one, and then two on the next try. One day, maybe, it won't make sense for me to pay for more donuts at all.

I don't even do the railyard anymore. Just donut farm.

I know the post you're taking about and it's a bit off imho.

The probability is straight forward, on average you'll pay $50k on every bonus box to get 3 (I've confirmed this result by recording hundreds of results).

If as you suggest in your example, it takes 10 KEM to make a bonus box (multiplier would be 754%), then the cost is $144k. The cost is lower on average to achieve 3 then it is to rebuy another bonus box.

The math changes when your multiplier reaches the point where you can buy bonus for less than the average cost of getting 3. ~3400%

All this presumes that the bonus box is perfectly random distribution, which it isn't.

On average, maybe. But that's a little overly simplistic. You have to break it down by scenario (i.e., what you get in your first box) to maximize your efficiency. Simplicity has it's virtues, too, so maybe you don't want to worry about it.

The scenario you're talking about is the point where it NEVER makes sense to pay for the next box, no matter what.
