Have you ever opened Infinity Nikki, spotted a free-code pop-up, and thought, “I’ll redeem that later”? Same here — and that’s exactly how I’ve missed rewards in gacha games before. Codes are one of the easiest ways to pick up Diamonds, Bling, Thread of Purity, Shiny Bubbles, and even Revelation Crystals, but they’re also one of the easiest things to forget. So I keep a checklist. The list below is the July 2025 code set from the reference I’m working from; since we’re in 2026, please treat it as a “test-it-now” list rather than a promise that every code is still live. Codes expire quietly, and nothing stings quite like finding a 1,880-Diamond code a month too late, right?

How I redeem codes without wasting time

The first thing to know is that you can’t redeem codes from the title screen. You need to finish the tutorial quest that unlocks the Pear-Pal. Once you have it, open the Pear-Pal, go to Other Settings, and look for the Other tab. That’s where the code field lives. Type or paste the code, confirm, and check your mail or inventory for the rewards. If the code doesn’t work, don’t keep hammering it — check for typos, extra spaces, and capitalization. Some codes are case-sensitive, and expired codes simply won’t go through.

I also recommend redeeming the biggest codes first. Why? Because if you only have five minutes, you want the 1,880-Diamond code before the 15,000-Bling code. Bling is nice, but Diamonds are the currency that hurts to miss.

The code list I’d work through first

Here’s the full set from the reference. I’ve kept the code text exactly as written, including mixed-case and non-English codes, because changing them can break them.

My personal priority order

If I were starting fresh in 2026, I’d try these first:

1. 100THDAYCELEBRATION — Diamond x1880, Bling x18,888, Resonite Crystal x1

2. dreamweavernikki — Diamonds x520

3. nikkihappybirthday2024 — Diamonds x500, Energy Crystal x2, Bling x12,600

4. Handinhand — Revelation Crystals x10

5. infinitynikki1205 — Limited-Time Revelation Crystal x20

6. MAYEVERYGIRLHAPPINESS — Diamond x200, Bling x18,888

7. NIKKIFIREWORKS, NIKKIEXCURSIONTIME, NIKKINEWBLOOM2025 — solid mixed rewards

Why these? Diamonds and Revelation Crystals are the “ouch” rewards. Bling and Thread of Purity are useful, but they’re not the same kind of heartbreak. The social codes — 1.2VERDISCORD, 1.2VERREDDIT, 1.2VERGLOBALGROUP, DISCORDSTYLIST, GROUPSTYLIST, REDDITSTYLIST, and the Japanese-language Discord code — are worth trying too, but they’re often the first to expire. That’s just how social campaigns work.

A quick reality check for 2026

Here’s the awkward part: a code list from July 2025 is old in live-service terms. Games rotate codes, tie them to events, or shut them off after a redemption window. I can’t magically verify every code in 2026 from a static list, and neither should you assume a code is permanent. My advice? Redeem in batches. Start with the high-value codes, then the social-follow codes, then the event codes. If a code fails, mark it off and move on. Don’t let a dead code ruin your session.

Also, be careful with “free reward” lists that ask you to log in somewhere or share account details. The only place I redeem codes is inside Infinity Nikki’s own settings. No external site needs your password. That’s not just a 2026 rule; it’s a forever rule.

What rewards should you actually care about?

• Diamonds: pull currency; always take these. 💎

• Revelation Crystals: free pulls; huge. ✨

• Resonite Crystal: rare and valuable. 🌟

• Energy Crystal: stamina; useful. ⚡

• Shiny Bubbles, Thread of Purity, Shining Particles: upgrade materials; good but less exciting. 🧵

• Bling: common; fine, but not worth a celebration. 💰

That’s the lens I use. If a code gives Diamonds or Revelation Crystals, I try it immediately. If it gives Bling, I still try it, but I don’t cry if it’s gone. And if a code from this July 2025 list still works in 2026? Great — that’s a happy little time capsule. If it doesn’t, at least you know before you spent an hour hunting for a dead code.

So, what’s the move? Open the Pear-Pal, hit the Other tab, and start with the big ones. Free Diamonds don’t redeem themselves, right?
