Cut fees by up to 25%
and let us bring the players too
From building your out-of-app store to driving traffic through Game8 and its 42 million monthly users — in as little as two weeks.
A store on its own does not generate sales. We provide both the storefront and the path that brings players to it.

Why Game8 Store
There are several ways to sell outside the app. What sets Game8 Store apart is that acquisition comes with the payment layer, not separately.

Rates reflect the Japanese market as of July 2026. Apple counts purchases made within 7 days of an in-app link tap; Google counts 24 hours. Reduced rates for small businesses, and the new Google Play structure taking effect on 31 December 2026, change these figures. Game8 Store transaction fees also vary by referral channel and payment method.
Features that move revenue and cut workload
More than a checkout: a system that works on your revenue, your workload, and your fans' enthusiasm.
Walkthrough wiki
Built to sell on the wiki, not just link out from it
At Game8, the same team designs and runs both the walkthrough wiki and the store. The purchase path sits inside the flow of the walkthrough, so players reach checkout while their intent is still high.
Traffic comes from Game8 itself, with 42 million monthly users, and because it never passes through an in-app link, no Apple or Google link-out fee applies.
A range of payment methods
Reach players without a credit card
Credit cards, convenience store payment, carrier billing, and online ID payments are supported, so players without a credit card still have a way to buy.
Built for more than in-app items
Sell more than in-app items
Alongside in-app items you can sell Steam download keys, digital items, and physical game merchandise.
Points
Keep players coming back
The shared Game8 Store points program gives players a better deal on every purchase. Game8 covers a set reward rate, and you can raise it further by funding the difference.
Useful for driving repeat purchases and lifting engagement during campaigns.
Coupons
Effective for both acquisition and retention
Issue coupons for specific items or a limited period, as either a fixed amount or a percentage off.
Ideal for collaboration events and anniversary campaigns. Game8 also distributes coupons at its own cost on a regular basis.
Limited offers
Control how often each player can buy
Cap purchases per player or per period — "one per customer", "first 100 only" — and optionally sync the purchase count with your game.
Gift codes
Instant rewards with no development work
You issue and manage codes on the store side, and players enter and redeem them directly on Game8 Store.
Because item delivery runs through the same API as a normal purchase, you can launch giveaway campaigns without any special development.
Dashboard
Improve operations with real data
Track transaction counts and revenue by channel in real time.
Daily and monthly totals, payment history, and monthly payout statements are all available, which helps with internal reporting and verifying campaign results.
In-app SKU and Adjust integration
Keep your existing SKU structure
Bring your existing in-app SKU structure across as it is, and measure referral performance through Adjust integration.

What you already run keeps working
Running your own web store or another external service? Nothing has to be replaced.
If you run your own web store
We do not compete with it. The roles differ.
Your own store mainly serves players who already spend, while Game8 Store works as the first-purchase entry point for new and low-spending players arriving from the walkthrough wiki.
Because the audiences barely overlap, the two do not take revenue from each other, and Game8 covers the acquisition side that in-house stores tend to struggle with.If you already use another external payment service
Your existing API work carries over.
The underlying design — confirming whether a purchase is allowed, then notifying completion — is the same, so logic you have already built can be reused.
What you add is mainly signature verification and a player information endpoint, which is far less work than starting from scratch. Running both services in parallel is also an option.
Questions we hear most often
Answers to the questions publishers ask us most about Game8 Store.
QDoes external payment violate app store policies?
App Store and Google Play policies do restrict purchase flows that link out directly from inside a game.
Game8 Store is provided purely as an external website, so you can operate it in line with those guidelines. Many titles are already running this way without issue.
Following the Mobile Software Competition Act, in force since December 2025, Apple and Google charge a fee when an in-app link sends players to an external site. Traffic that never passes through the app — such as referrals from a Game8 walkthrough wiki — falls outside that scope. (As of July 2026. Please check each platform's current terms.)QHow long does it take to launch?
From application to going live takes as little as two weeks, and typically four to six weeks.
The exact timeline shifts with the review and the technical setup involved, but a dedicated support team works alongside you to keep things moving.QHow secure are payments and personal data?
You can rest easy on both. Game8 Store works with a Japanese payment service provider to deliver a PCI DSS compliant payment environment.
Personal data is handled strictly in line with our privacy policy: we never provide it to third parties or use it for any other purpose.QAren't refunds and chargebacks a lot of work?
Game8 Store handles the whole chain on your behalf, from payment processing through refunds.
If a chargeback (a refund demand arising from fraudulent use) does occur, we process it on our side, so there is no complicated handling for your team.QCan a company based outside Japan use Game8 Store?
Yes. For companies based outside Japan we operate as the Merchant of Record (MoR).
That removes the need to sell in Japan through a local entity, and we handle tax, invoicing, and payments on your behalf.
Publishers outside Japan are already live with us, and we can handle contracts and support in English.
How launching works
01
Apply
Fill in the required details and submit the application form, or contact your representative directly. We will talk through your needs and recommend the right set of options.
02
API work and catalog decisions
We complete the system integration (API implementation) and settle on the items, prices, and store copy. We can also help produce the images and descriptions.
03
Payment testing
Before you go live, we verify the payment flow and everything shown on screen in a test environment. Any issues or adjustments are handled at this stage.
04
Go live
Once setup is complete you can start selling the same day. Support for operations, promotion, and features continues after launch.
Open an out-of-app store that grows revenue and profit
- Referrals from Japan's largest game walkthrough network support new player acquisition and revenue growth
- Fees up to 25% lower than in-app purchase (26% on Apple, 30% on Google) improve your margin
- Coupons, points, limited-time sales, and other revenue-accelerating features come as standard
