Invite a Friend - event rules

When

When: 20 Oct 2026, 00:00 - 1 Nov 2026, 23:59 (Thailand time)

How to join

Pre-register at piggydays.com, then copy your invite link (shown after you sign up and in the Account Center on the website) and send it to friends any way you like. Each friend who pre-registers and confirms their email through your link during the event counts as 1 successful invite.

Up to 10 friends count; each step is given once.

How invites count

  • The friend must be a new pre-registrant (never pre-registered before), sign up through your link and confirm their own email (Google / Apple / LINE sign-ups count at once).
  • One friend counts for one inviter only: the first link used to sign up wins and is never changed later.
  • Self-invites, the same email written differently (for example dots or +text in Gmail) and disposable emails do not count.
  • Sign-ups from the same internet network count at most 2 for one inviter.
  • Unusual counts (for example more than 15) are reviewed before rewards are sent. Duplicate sign-ups, fake emails and bots do not count and may be disqualified.
  • A friend who later unsubscribes from emails still counts; a friend's pre-registration deleted before delivery does not.

Delivery

Rewards are delivered automatically to your in-game mailbox at launch on 1 Nov 2026, to the game account linked to your pre-registration (the same rule as the pre-registration rewards). Invites added on 1 Nov go out in the final delivery on 2 Nov. If you link your game account later, they arrive at your next login.

Sharing

No timeline sharing or tagging required; send the link any way you like. One account per person.

Personal data

We keep your invite code, who signed up through whose link and fraud-check data (a hash of the normalised email, a shortened IP network) only to count invites and deliver rewards, and delete them within 30 days after the final delivery. See the Privacy Policy
