#Asset and Listing Guide

Submission form: 2MB per image, 2.5MB combined across icon, cover and up to three screenshots. Recommended cover source: 1600×900.

How your game looks in the catalog is determined by the assets and text you register. This document covers the specifications for the icon and cover image, and where and how the title, tagline, and description appear.

#1. Icon

The image shown in the most places: catalog lists, search results, the center of tiles that have no cover, favorites, and more.

Production tips:

• Keep the key elements (symbol, brand mark, character) within the central 80% — at 512px that is the central 410×410px safe area. Icons are also shown at small sizes (24–64px), so edge detail won't be visible and corner masking can clip it. Graphics that spill past the safe area read as visually off-balance.
• Keep text to a minimum. The game name is always displayed separately next to or below the icon.
• A screenshot simply scaled down turns muddy at small sizes — we recommend dedicated art centered on a symbol or character.

How to register: upload in the icon step of the submission wizard. After listing, the signed-in owner can replace it anytime under My games — addresses are content-hash based, so the new image appears on every screen the moment it's replaced.

#2. Cover (Tile Art)

The landscape image used as the background of game tiles on the home and category pages. With a cover, the tile is filled with an actual scene from your game; without one, it falls back to the icon plus a gradient. Tiles switch to a live game preview on mouse hover, so the cover is responsible for the "static first impression."

Production tips:

• Put the main graphic in the center, and keep the bottom 25% clear. The game name and tagline are overlaid, along with a gradient, at the bottom of the tile — text or a logo placed there gets clipped or washed out. If you include a logo, top or center placement works best.
• We recommend actual game scenes (art based on in-game screenshots) — they lead naturally into the live game preview on hover. Scenes that don't exist in the game are grounds for rejection in review.
• Don't pack in detail. On mobile the cover renders at less than half size — the more text it carries, the less anything reads. One strong scene communicates best.
• Avoid pure-white or pure-black flat backgrounds. The service renders in both light and dark themes, and in one of them the image boundary disappears into the page background.
• Avoid content that is only valid for a period (seasonal events, update teasers) — it becomes an image you have to keep replacing.

How to register: upload in the cover step of the submission wizard, or replace it anytime after listing under My games.

#2.5 Screenshots (optional)

Shown as a horizontal gallery at the top of the game's detail page. If the cover is the first impression, screenshots are the evidence of what a player will actually see.

• Unedited game frames work best — a gameplay moment, a results screen, the core UI; three is plenty.
• Unlike the cover there is no name overlay, so the bottom-margin rule does not apply.

How to register: upload in the screenshots step of the submission wizard, or replace all three at once anytime after listing with the "Screenshots" button under My games.

#3. Text Listing

• The tagline needs only one of Korean or English. An empty language is substituted with the other. That said, filling in both improves exposure quality in each language market.
• The description is shown as-is on the play page — write the controls, the goal, and the features in separate paragraphs. Line breaks are preserved.
• Under the review criteria, a description that doesn't convey what the game is will receive a change request. See Review Policy §2.

#4. What the Spec Card Shows

The spec card on the play page is generated automatically from your registration info:

#5. What Not to Do

• Putting other stores' badges, award marks, or ranking claims into your images
• Using scenes that don't exist in the actual game (exaggerated promotional art) as the cover
• Using images or fonts whose copyright hasn't been cleared — this is grounds for rejection in review
• Excessive text on the icon and cover — the platform always displays the name and tagline separately
