How to Get Vouchers on Hay Day?
Open your boat
Boats and truck orders are best, tho i too get so-so luck with truck orders, keep getting same green orders over and over again. The mystery lock boxes often give vouchers close together. Start searching now, i,ve found more vouchers (mostly blue) from the mystery boxes within the last couple days. Of course, that may be level dependent, who knows? Nothing harmed in giving it a shot. Good luck!
 
Load up cargos
The Load Cargo menu shows the item requests sent out by other players. Item request are usually farm produces like fruits and dairies. To send out cargos to your friends, tap any of the open cargo box with a picture of an item requested. Tap it as many times as needed (depending on the number of requested items) until the cargo box closes.
 
The easiest way to get vouchers on Hay Day is by opening random red mystery boxes which can be found on your farm and also when you visit other farmers. Rewards are either diamonds or vouchers especially when visiting your neighbor’s farm. Sometimes I also get tools for mining and for cleaning up the farm.
 
How to Get Color Vouchers?
From our experience, we have noticed that you are less likely to get the green vouchers if you fill your boat order right away. That means if you are trying to get blue, purple or gold vouchers try filling your boat orders quickly. We have also found that the most popular vouchers from truck orders are gold and purple. The tool boxes have also given us some purple as well just make sure you don’t use your gems to unlock them because it may be a lot before you get the right color voucher.
