A Mini Trolley Problem Genshin Impact is the commemorative Gadget delivered with the fourth and final Missive of Grace anniversary mail on October 1. Eligible players receive it alongside 400 Primogems, completing the four-day mailbox campaign that distributes 1,600 Primogems and the extra sixth-anniversary items.
Unlike a furnishing that needs to be placed in the Serenitea Pot, A Mini Trolley Problem Genshin Impact is listed as a Gadget. Its playful effect matches the item name: opening the tiny train carriage randomly produces either a snowball or fireworks, making it a novelty anniversary item rather than a progression reward.

Log in on or after the October 1 mail release, open the in-game Mail menu and find the fourth Missive of Grace anniversary message. The attachment contains 400 Primogems and A Mini Trolley Problem. The mail campaign requires Adventure Rank 2 or higher, so the Gadget is available to very new accounts without any Snezhnaya Archon Quest requirement.
A Mini Trolley Problem Genshin Impact is not obtained from the Resplendent Starlight login page. That separate October 1 event gives Intertwined Fates and other login rewards. If you are looking for the Gadget, the correct place is the mailbox, specifically the final Missive of Grace message.

What A Mini Trolley Problem Genshin Impact does
The Gadget is a tiny train carriage that can produce one of two playful results when opened: a snowball or fireworks. It is designed as a commemorative novelty rather than a combat tool, so there is no reason to save charges for bosses or exploration puzzles. Use it when you want the visual effect and keep it as part of the anniversary collection.
A Mini Trolley Problem Genshin Impact sits alongside Conductor of the Ya-ho as one of the special Gadgets added in Version 7.1. The two items come from different anniversary mails. Conductor of the Ya-ho arrived on September 28, while A Mini Trolley Problem arrives with the October 1 message.
Where to find the Gadget after claiming it
After collecting the mail attachment, open your Inventory and check the Gadget section. If A Mini Trolley Problem Genshin Impact is not immediately visible, close the Mail screen and reopen the Inventory or reconnect once before assuming the claim failed. The important check is whether the mail attachment has actually been collected.
Do not search the Serenitea Pot furnishing list first. A Mini Trolley Problem Genshin Impact is a Gadget, and that classification determines where it appears. Once it is in the Gadget inventory, select it through the normal Gadget interface and use the item to trigger its random snowball or fireworks result.
What if the October 1 anniversary mail is missing?
First confirm the account has reached Adventure Rank 2 and that October 1 has begun on the server you use. Anniversary mails are released according to the event schedule rather than your device clock alone. If the date is correct, reconnect and open Mail again before changing any game files or reinstalling the client.
The four Missive of Grace messages each have their own release date and a 30-day mail expiry after arrival. A Mini Trolley Problem Genshin Impact therefore should be claimed promptly even though the broader Version 7.1 celebration continues. Leaving a commemorative item in an expiring message is an unnecessary risk.
How this completes the Missive of Grace rewards
The October 1 message is the final part of Missive of Grace. September 28 delivered 400 Primogems and Conductor of the Ya-ho, September 29 delivered 400 Primogems and two Fragile Resin, September 30 delivered 400 Primogems and one Sanctifying Elixir, and October 1 adds the final 400 Primogems plus A Mini Trolley Problem Genshin Impact.
Together those mails supply 1,600 Primogems. The anniversary also has the separate Resplendent Starlight Daily Login for 10 Intertwined Fates, so collecting A Mini Trolley Problem Genshin Impact does not mean every anniversary reward has been claimed. Continue the seven-login track after the mailbox campaign is complete.
A Mini Trolley Problem Genshin Impact is easy to miss only because it arrives through Mail while several other anniversary systems are active at the same time. Claim the October 1 Missive of Grace attachment, find the Gadget in your Inventory and keep checking Resplendent Starlight separately for the remaining anniversary Fates.
