Genshin Impact Top Up Guide 2026: Cheapest & Safest Way to Buy Genesis Crystals

If you've been playing Genshin Impact for any length of time, you already know how fast Primogems disappear. A new banner drops, you lose a 50/50, and suddenly the stash you spent six weeks building is gone in ten minutes.

Topping up Genesis Crystals is the fastest way to close the gap — but where you buy them matters. The official HoYoverse store charges full price with no discounts. Third-party platforms like Kardz offer the same Genesis Crystals at lower prices, with faster checkout and more payment options.

This guide covers everything: what Genesis Crystals actually are, how the top-up process works, which server to pick, and how to avoid the mistakes that cause failed top-ups.

Genesis Crystals vs Primogems: What's the Difference?

A lot of new players get confused here, so let's clear it up.

Primogems are Genshin's general premium currency. You earn them through quests, daily commissions, exploration, events, and redeem codes. They're used to buy Intertwined Fates and Acquaint Fates for pulling on banners.

Genesis Crystals are the paid currency — you can only get them by spending real money. They convert to Primogems at a 1:1 ratio, so 980 Genesis Crystals becomes 980 Primogems. The reason they exist as a separate currency is the Initial Top-Up Bonus: first-time buyers at each denomination get double Genesis Crystals, which is the best value you can get in the entire game.

When you top up on Kardz, you're buying Genesis Crystals, which you then convert to Primogems inside the game.

Initial Top-Up Bonus: The Most Important Thing to Know Before You Buy

Every top-up denomination in Genshin has a first-purchase double bonus. Buy 980 Genesis Crystals for the first time at that tier and you get 1,960 instead. This applies to every level from 60 up to 6,480.

The catch: once you've used the bonus at a given tier, it's gone permanently — unless HoYoverse resets it. The most recent reset happened with Version 6.0 (September 2025) to celebrate the game's 5th anniversary.

What this means for you: If you've never topped up before, or if you topped up before the Version 6.0 reset, you currently have double bonuses available at some or all tiers. Use them before you spend Primogems on a banner you don't actually need.

The double bonus applies regardless of where you buy — official store or Kardz. So you might as well buy at the discounted price.

How Much Does Each Pack Cost on Kardz?

Kardz regularly offers discounts on Genesis Crystal packs compared to the official HoYoverse store price. The exact price varies by region and any active promotions, but the discount structure is consistent across packs.

Head to the Kardz Genshin Impact top-up page to see current pricing for your region. First-time buyers on Kardz can also apply a new user coupon on top of existing discounts, which brings the effective price down further.

Pack sizes available: 60 / 300 / 980 / 1,980 / 3,280 / 6,480 Genesis Crystals, plus Welkin Moon and Battle Pass.

Self Top-Up vs Login Top-Up: Which One Should You Use?

Kardz offers two methods for Genshin Impact. Understanding the difference saves you time.

Self Top-Up (Recommended)
You enter your UID and server directly into the Kardz checkout. No account credentials required — Kardz credits your account through official channels without ever logging into your game account. Fastest option, usually delivers within 1–3 minutes after payment.

Login Top-Up
You provide your account email and password to Kardz support, who complete the top-up manually. Takes around 15 minutes. Useful if Self Top-Up isn't available for your specific region or pack type.

For most players on Global, Asia, Europe, or HK/TW servers, Self Top-Up works fine and is the better option. Change your password after Login Top-Up as a precaution.

How to Find Your Genshin UID

Your UID is the number you need for Self Top-Up. Here's where to find it:

1. Log into Genshin Impact on any device

2. Tap the menu icon in the bottom-right corner of the screen

3. Your UID appears at the bottom of the screen as a string of numbers

It typically looks like: 800XXXXXXX (Asia), 700XXXXXXX (Europe), 600XXXXXXX (Americas), 900XXXXXXX (HK/TW/MO)

The first digit tells you your server. This matters for Step 3 below.

Step-by-Step: How to Top Up Genshin on Kardz

Step 1: Go to kardz.com/game/genshin-Impact

Step 2: Select Self Top-Up or Login Top-Up

Step 3: Choose your Genesis Crystal pack

Step 4: Enter your UID and select your server region

• Global = Americas / Europe / Asia server

• HK/TW = Hong Kong, Macau, Taiwan server

• Getting this wrong is the most common cause of failed top-ups — double check before paying

Step 5: Select your payment method and complete checkout
Kardz supports Visa, MasterCard, PayPal, Apple Pay, Google Pay, and various regional payment options

Step 6: For Self Top-Up — crystals arrive in 1–3 minutes. Log into the game and check your mail or currency balance. For Login Top-Up — stay logged out until Kardz support confirms completion (around 15 minutes)

Which Server Am I On?

This is the single most common mistake. Picking the wrong server means your crystals go nowhere.

If you're unsure, open Genshin, go to Settings → Account, and your server is listed there. Match it exactly to what you select on Kardz.

Is Kardz Safe for Genshin Top-Ups?

A few things worth knowing:

Self Top-Up works through official channels — Kardz credits your account using your UID without accessing your login credentials. HoYoverse sees this as a normal purchase and your account is not at risk.

Login Top-Up involves sharing account credentials. Kardz has been operating since 2008 and has processed millions of orders, but as a general rule, change your password immediately after any Login Top-Up is complete.

Kardz offers a full refund guarantee on failed top-ups. If the crystals don't arrive and the issue is on their end, you get your money back.
