If you’re a Genshin Impact fan who’s been itching to spruce up your devices with fresh, Teyvat-themed vibes, HoYoverse just dropped a treat that’s bound to make your day—literally. The studio has rolled out its September 2026 calendar wallpapers, tailored for PCs, mobile phones, and even Apple Watches, and they’re free for all Travelers to save and use however they please. No fine print, no hoops to jump through just to grab a cool background; it’s a straight-up win for anyone who wants to carry a piece of Teyvat with them every time they check their phone or fire up their laptop.
But wait, there’s more than just pretty wallpapers here. HoYoverse has paired the wallpaper drop with a limited-time event that gives Travelers a shot at scoring 160 Primogems—enough for a full 10-pull on the current banner, which is a big deal for anyone saving for their favorite character or weapon. The event runs from August 31, 2026, all the way through September 8, 2026, ending at 23:59 UTC+8, so you’ve got just over a week to lock in your entry before the window slams shut. Winners will be announced on September 15, 2026, so mark that date on your new September wallpaper if you’re hoping to get lucky.
Participating is a breeze, but the rules vary a little depending on which platform you’re using, so it pays to pay attention to the fine print. Let’s break it down:
How to Enter by Platform
| Platform | Required Actions | Key Notes |
|---|---|---|
| X (Twitter) | Like and share the official event post | Your account must be public, and you need to be able to receive private messages. Winners will get a DM to submit their UID, so don’t ghost that message! |
| Facebook, Instagram, Naver Cafe, Telegram, VK, Reddit | Like the post and leave your Genshin Impact UID in the comments | Again, keep your account public—private profiles won’t cut it for eligibility. |
The prize pool is 160 Primogems for 100 randomly selected winners, and that’s the total across all platforms. There’s no separate allocation for each region or social media site, so every entry, no matter where it’s posted, has an equal shot at being picked. That means if you’re active on both X and Reddit, you can enter on both—just keep in mind that you can only win once, even if your entries are selected on multiple platforms. If that happens, the prize will go to the platform where you first posted your entry, so make sure you’re keeping track of your submissions.
Now, let’s talk about the fine print that’s easy to miss but super important. First off, don’t post anything that violates laws, community rules, or has nothing to do with the event—spamming ad links or off-topic content will get you disqualified faster than you can say “Paimon’s emergency food.” Plagiarism is also a big no-no; if you’re using someone else’s work, you need to cite the original source and get permission, or you’ll be out of the running. And if you win, your UID will be disclosed on the event platform, so make sure you’re comfortable with that before you enter—though HoYoverse does promise to protect your UID per local privacy laws, so it’s not like your personal info is being thrown around.
If you do win, make sure you submit your UID correctly—if you mess up the numbers, HoYoverse won’t reissue the Primogems, so double-check that string of digits before you hit send. The rewards will be sent out within 30 business days after the winners are announced, so you won’t have to wait forever to add those Primogems to your stash. And if you have any issues or objections to the winners list, you can reach out to customer support via email or in-game, but if your entry is found to be against the rules, you’ll lose your prize and get banned from all future community events—so it’s not worth cutting corners.
All in all, this is a pretty sweet deal for Travelers. You get to grab some gorgeous new wallpapers for all your devices, and you’ve got a shot at scoring free Primogems just for liking and sharing a post or dropping your UID in the comments. It’s low-effort, high-reward, and a great way to kick off September with a little bit of Teyvat magic. So head over to Genshin Impact’s official social media platforms—X, Facebook, Instagram, TikTok, YouTube, HoYoLAB, or Reddit—grab your favorite wallpaper, and enter the event while you’re at it. Who knows? You might just be one of the 100 lucky Travelers walking away with 160 free Primogems. Just don’t sleep on the deadline—September 8 will be here before you know it!

In the case of HoYoverse’s September 2026 wallpaper release, the combination of free device backgrounds and a low-effort Primogem giveaway reflects the kind of fan-service strategy that keeps players checking official channels regularly.
