Trade rules and filters

Why do I see “Add at least one sticker the user is missing”?

This message appears when the user you’re trying to trade with has not enabled star-based offers (Receive proposals for stars).

• What it means:
  You must include at least one sticker they don’t already have.
• Why this exists:
  To ensure the trade is actually useful for the other user, instead of sending duplicates they don’t need.

Why do I see “This user trades for stars. Minimum X stars required for this sticker.”?

This message appears when the user has enabled the “Receive proposals for stars” option.

• What it means:
  The total value of the stickers you offer must be higher than the value of the sticker you’re requesting (minimum +2 stars or more).
• Why this exists:
  Some users enable this option when they are close to completing their album. In this phase, they may accept duplicates instead of missing stickers, but only if the total number of stars offered is higher than the requested sticker
• What’s the goal:
  This helps them accumulate stars, which can be used in the game to open vaults and earn rewards.
• In short:
  You’re not trading for stickers anymore, but for total star value.
• Important
  The minimum number of stars may vary depending on the sticker you’re requesting.
