KWIK-E-MART (also known as KEM) farming guide.

Statistically the burns box offers the best rate of return, but you will wind up with a lot of stuff you may not want in your town. That’s why I’ve never used the box. I buy mini nukes and jet bikes when they are in the Vault.

Either way I just hide it behind buildings

and the Lard lads earn cash so it helps with farming in another way

There might be a "build your own" with towers and gateways and walls . . .

@4junk3000 - they're new but along those lines if I got it right . . . likely won't be crafting though, expect packs for sprinkles to add extras
EDIT - started re hiding bonus items then you mentioned castles so mea culpa too for replies

Yeah, that was what i was expecting. But is it possible to tell how long time it will take to reach for example 700% bonus, and is mystery boxes the best way for it? And also ive now gone from lvl 65 to 105 since the first post, how does it work when you need more XP for each level-up? Im realizing im asking a lot of questions here, possibly annyoing ones. Sorry about that, but im struggling to find a good balance between earning donuts and earning money

On my B town, I started farming after I acquired all the Springfield Heights properties, which put my bonus at about 180%. As long as you can farm more donuts than you will spend keeping the collider going, it is worth the effort. My recommendation is to start with 24 KEMs at a time, as the XP return per game money spent is at its highest. This is my town where I haven’t spent a dime on the game, and now my bonus is about 535 after 15 months or so, and I’m at level 939. I can now farm enough sprinkles to buy all premium content in events and a couple catch-up items. (We won’t go into how much real money I’ve spent on my A town). Good luck and happy tapping.

Little lady justice and the whale are great if you are near to maximum item limits and donuts are not an issue to you.

Can I get some advice on the best Premium items to buy to get my multiplier up? I am L939 and currently my multiplier is 252.55%. I find that I can KEM for a few days but then I have to wait a couple again to let my cash reserves refill.

Mystery boxes average 8-10 donuts per 1%
Jet bikes cost 20 donuts (including 10 donut discount) which is 10 donuts per 1%

A little help from those who know please?
I have about $250 million IGC, 260% multiplier, 370 donuts, at Level 501.
Am I in a good position to KEM or Rat Truck farm, and what I’d the better proposition in my place?
I can commit to 4 hour check-in intervals, as I also have the She She Lounge hopping while Patty smokes all day.
With the SH additional multiple, I’m over 500% xp.

Rat truck will take your money faster. So i would start your hand at KEM first and see where it goes then.

Also SH only adds 153% max if you have the buildings out and the islands at the correct level.

I don’t have any island hideaways yet, but if this works out, I will’
