Ive been using them on this kingdoms tab of the laboratory, but it all seems really…useless?? I finished all the ones in the cookies tab, and did the efficiency of research and the extra storage ones, cleared all land, maxed all buildings, idk if it would be more beneficial to upgrade cookie houses? My most leveled up one is lv 13, and idk how efficient it becomes later on lol.
