Goddess of Victory : Nikke - BBQ Master Mini Game - Easy 12k+ Points (iOS Strategy)

The basic strategy here is to take advantage of the quick app suspend feature on mobile devices by swiping up from the bottom of your tablet/phone. When suspending the app, the game should freeze frame and you’ll be able to see what orders are currently placed. During this time, you can take note of all the ingredients for one order at a time and the path your fingers will have to take to quickly make the order. Once you’ve got an order memorized, resume the app and the game should unpause and you can get perfect orders easily and quickly.

It can take some time to get used to this method and rng is still a factor when it comes to x2 fever and x2 point orders, but if you stick with it, you should be able to get 12k+ much quicker than the legitimate way.

I'm unsure if this exact method will work on Andriod as my Pixel seems to be a bit different. On my Pixel, I have to swipe up and minimize the Nikke app completely so that that phone returns to my phone's homescreen. From there, I have to swipe up again to open the app manager and the Nikke app will be free framed until you click back into the game.
