What is Sweetheart Collector?
Sweetheart Collector is a newly released waifu-collecting card RPG (January 2026) published by Funz Mobile (also listed as Shanghai Hahuan). The game differentiates itself with a "Flavor" theme—every girl corresponds to a specific taste or cuisine, and you must use "Taste Synergy Skills" in battle. It features over 100 characters with Live2D interactions, a cooking/dating simulation component, and a storyline where you nurture relationships to unlock intimate memories. It is designed as a casual side-game with automated battles and generous login rewards (including a "Twin Waifus" guarantee for new players).

Why Aren't My Sweetheart Collector Codes Working?
Sweetheart Collector codes can stop working at any time. Here are the most common reasons a code might fail and how to fix each one:
- The code has expired. Event codes and milestone codes tend to expire quickly — sometimes within hours. Try redeeming new codes as soon as they appear on our list to avoid missing out.
- Double-check for typos. For Sweetheart Collector, capitalization doesn’t matter for these codes, but spelling does. Even one wrong letter or number will cause the code to fail — copying from our list is the safest option.
- Already redeemed. Codes are single-use. If you’ve redeemed a code before — even months ago — it’s permanently claimed on your account and can’t be used a second time.
- Check your in-game mail. Some rewards are sent to your mailbox rather than added to your account instantly. Look for a notification icon or mail tab after redeeming.
