You CAN, but I don't think Supercell approves of it. It's risky, and you can lose one of the games pretty easily. You'd have to use two Game Center IDs on one iPad, and if something goes wrong you could lose one of the farms.

There are a number of threads on the Hay Day forums about issues related to using two Hay Day games on one device: http://forum.supercell.net/showthread.php/58021-Same-hay-day-farm-on-two-Game-Center-accounts-on-the-same-ipad http://forum.supercell.net/showthread.php/247837-Linking-iPhone-to-iPad-w-Two-Seperate-Game-Center-Accounts I would suggest reading them before making a decision, and also asking on the forums for an official response. I'm not involved with Hay Day's development or the company that makes it.
