Hay Day pie oven is a Hay Day production building unlocked at the farm level 14. It costs players 2,200 Hay Day coins in Hay Day Store.
Hay Day pie oven can be used to make carrot pies, pumpkin pies, bacon pies and more. At first, it has 2 slots to produce food. It can be added more slots by Hay Day diamonds when necessary.
There is a mastery system on Hay Day pie oven from the farm level 15 onwards to boost the game. The more hours players crafts items using pie oven, the more stars of the mastery system players can earn.
If you are lower than 15, you won’t see the mastery system icon near your production buildings.
40 hours of pie oven use earn one star, which can make all goods worth an increase of the price by 10% from truck orders.
160 hours earn the second star, which can make all goods worth an increase of the experience points by 10% from truck orders.
640 hours reward the third star, which can produce all goods 15% faster.
A tip to speed up mastery: never let it stop, and fill the pie oven slots with the longest items to be crafted when left.
