Upgrading the pizza oven in "Katie Island Adventure" can unlock more advanced pizza recipes. However, many players do not know how to upgrade the pizza oven. It is actually very simple. First of all, when you make pizza for the first time, you will use dough and other One ingredient, but the amount of this ingredient will eventually increase, and the pizza oven will be upgraded when your friendship level with Liezi reaches 9.
How to upgrade Katie Island Adventure Pizza Oven
When making pizza for the first time, you will use dough and another topping, but the amount of this topping will eventually increase. When your friendship level with Reiko reaches 9, the pizza oven will be upgraded, and two ingredients are required (except the dough) when making the pizza.
This will unlock many new recipes, so be sure to try new ingredient combinations! Although there are not many pizza options in the game, you must try to make all pizzas.
When your friendship with Reiko reaches level 15, you will get a plan to make your own pizza oven that can be placed in the cabin. To make this oven, you need five sparks, ten gold ingots and 100 dough. This is a big challenge, so you must continue to give gifts to Liezi every day.
