Thank You!If you are talking about the Ancient Knowledge Instants then you use them while you are in any Ancient Wonder research progress tab which is the 2nd tab.. While in this tab you will see a picture of a book (Knowledge Point) with a + icon next to it.... click the book and it opens a screen that shows all your available Knowledge points instants in your inventory to use, then click on the ones you wish to apply to that Wonder...
Also make sure you have unlocked the Ancient Wonder research in the research tree chapter 2.. If you have not unlocked it yet then you can not build an Ancient Wonder or use the Ancient Knowledge Point Instants yet...
Thank you, good to know!The ancient knowledge instants don't use an hourglass, that is for timer instants. What you are looking for is the book icon on ancient wonders:
View attachment 8201 That's where you can use them.
Thanks!The icon is different on mobile version :
