Heartopia Mailbox Stars Guide: Home Popularity & Pop Star Hidden Achievement

Hana    April 03, 2026    Guides    Comment   

Have you noticed the star icons appearing under your home mailbox? These stars indicate your Home Popularity, which is calculated based on the number of likes received from other players during specific event periods. 

To gain more likes, ensure your home is decorated attractively to encourage other players to visit and interact.

Note: This guide is regularly updated to match the latest Heartopia version. Last update: April 03, 2026.

Star Levels (Like Requirements)

The following is the specific number of likes required for each star level:

• ⭐ Star: 0 - 19 Likes
• ⭐⭐ Stars: 20 - 49 Likes
• ⭐⭐⭐ Stars: 50 - 99 Likes
• ⭐⭐⭐⭐ Stars: 100+ Likes

Maximum Rating Limit

The maximum display on the mailbox is 4 Stars. Even if your home receives hundreds or thousands of likes afterward, the star indicator will not increase further as 4 stars is the highest achievement level.

Hidden Achievement

Once you have successfully accumulated a total of 100 Likes, you will automatically unlock a Hidden Achievement called Pop Star.
