Rolling Hills: Make Sushi, Make Friends

There is a total of 51 recipe that you need to collect :

first of some of the recipe are unlock after some main quest who as a number in your menu so check if you have completed them all.

You need to reach max level whitch is 20 for a total of 19 new recipe (one for eatch level).
Then you need to be friend whit everyone because they give at level 1, 3 and 5 an new upgrade and for level 2 or 4 they give you randomely a new recipe or a new background for your shop. So reach level 5 to make sure that you have all of the recipe.

when you first launch the game their is a day count that you cannot see but every new day you get a "event". what you need for the recipe here is the sushi traverler a the left of the place every 7 day, she will sell you 6 new recipe for 100, 200, 400, 600, 800, and 1000gold every 7 day so make sure to buy it when you see her because you can only buy one at a time. Note that you will have a challenge to buy something from her if she is in town.

Speaking of challenge you will need more than 200 point to buy the 10 recipe to the "geek" a new pnj that you unlock after the wifi quest. she echange challenge point for hat or recipe you dont need to buy everthing just the recipe and 10 hat for the 100%.

Then you need to do the campaign quest their is three secret recipe than you have to do to unlock the three new spirits in your city. this is part of the campaign and unmissable the only recipe that count here is the final one (robot shap sashimi) that you get after the credit.

Then what was missing for me is the succes menu when you pause the game you can go into a menu call succes where the succes of the game give you something for completing them you need to collect them in this menu for a aditional 5 more recipe. not that having all 51 recipe give you 5000 gold.

So to make it quick you need :
level 20 shop
level 5 friendship whit everyone (even the clown and the hero who come later in the game)
buy 6 recipe from suchi traveler
buy 10 recipe from the geek(dont remember her name)
every quest done to the final one and credit watch. ( note that if you finish the main quest you can just continue playing on the same fill)

this succes should unlock after the autosave of a day when you completed your recipe books.
Good luck!
