1 During the event, players who log into the event page and bind their account can generate a personalized invitation poster or link to invite friends to participate.

After participating in the 'Return to 2004' event, the system will determine if the player is a returning IP user based on account info; unmatched users can still join the invite event.

When 3 friends enter the event through your exclusive link and complete participation, the invitation relationship will be recorded. The system will verify based on the historical relationship between both parties and light up the corresponding puzzle piece according to the inviter's user type:
User Type A: If any 2 of the following match with the inviter—same server, same class, same clan, or same starting year—you can light up 3 shining puzzle pieces;
User Type B: If any 1 of the above conditions is met, you can light up 2 shining puzzle pieces;
Category C Users: Users with previous records or paid test participants, can light up 1 shining puzzle piece;
Category D Users: Users with no relation, can light up 1 normal puzzle piece.

4. After players complete puzzle lighting tasks, they can claim corresponding rewards as prompted on the page. Reward quantities, claiming methods, and distribution times are subject to the event page. If cheating, farming, fake invitations, or other violations are found, the official team reserves the right to cancel event qualifications and rewards.
