Our Review and Publishing Process

To ensure that your game reaches its highest potential, every submission undergoes a

thorough review by our team of content specialists. This process is designed to assess

whether your game meets our quality standards and the expectations of our publishers’

diverse platforms.

Submission and Initial Review:

When we receive your game, it enters our review queue.

The initial assessment typically takes up to one week, during which our team evaluates

your game’s compatibility with our platform’s standards and publisher needs

Approval for Publication:

Once the assessment determines that all essential requirements

are met, your game is given the green light and can be prepared for publishing.

ollowing

the developer guidelines outlined below will increase the likelihood of a swift assessment

and approval process.

Feedback and Revision: Should your game require any adjustments, our team will provide

relevant and actionable feedback to help you refine the game. This collaborative approach

ensures that your game aligns with our guidelines and appeals to the target audiences of

our publishers

Ongoing Optimization: Post-publication, we continuously monitor game performance and

market trends. This might lead to additional suggestions for enhancements or necessary

adjustments to improve game performance across platforms. Our goal is to always help

maintain the life-cycle of your games, especially after launch.

1. Game Quality Standards

GameDistribution accepts a wide variety of games, yet we also aim to make sure that the

games we publish are of great quality. To achieve this, we ask that all submissions meet the

essential requirements outlined below.

1.1 Replayability

Your game should aim to promote high levels of engagement and interactivity. This results in

higher retention rates and extended gameplay sessions. In order to increase your game’s

replayability, we recommend developing features such as

Level structure & level overvie

Challenge

High score

Character customization

1.2 Sound

Sound should be considered a vital component of your game design, especially when

considering replayability and immersion. Your game must include sound elements such as

background music (BGM), sound effects (SFX) and User Interface (UI) sounds. In order to

elevate the sound implementation in your game, please consider the following

Take advantage of the sound design to set the tone and atmosphere of the game by using

engaging music that captures the overall theme

Promote immersion through additional SFX when completing a level, hovering over UI

elements, or unlocking an achievement

Select genre-specific music and SFX to enhance player immersion. For example, eerie and

suspenseful music works well for a horror game

We recommend designing a toggle button for both sound and background music to improve

user interface.

1.3 Visuals

1.3.1 In-Game Graphics

In-game graphics should be of high quality, polished, and consistent throughout. All player

and environmental textures should be fully visible.

1.3.2 UI Design

It is required that there are no overlapping UI elements that obstruct player interaction. For

example, avoid overlays that block access to essential buttons like sound or play.

Buttons and controls must be easily recognizable and understandable. Use universal icons

and visual language whenever possible (e.g., for play). The play button should always be

visible to guide players toward starting the game. Text should be clear and readable.

1.3.3 Gameplay & Tutorial

The game’s objective should either be intuitive to users or explained through a simple tutorial.

Any instructions or deviations from generic controls should be clearly outlined for the player

before the game begins.

In order for an elevated user experience overall, the game should run smoothly with limited

frame-drops and without user input delays.

1.4 Game Content

To guarantee a comfortable and appropriate gaming environment, games should be tailored to

their intended audience. You can select specific age groups and genders when submitting

your game to distribute it to the right audience. Please keep in mind that games with

inappropriate content will not be picked up or featured by most of the platforms hosted by big

partners.

Games are prohibited from including

Political bias or offensive religious conten

The use of explicit references to alcohol, drugs, or sexual theme

The use of racial, discriminatory, or prejudicial conten

Excessive use of violence

Finally, for games with user-input content, such as custom player names or chat options,

mechanisms should be in place to prevent the use of inappropriate language or any other

harmful content by players.

1.4.1 Avoiding Copyrighted Names in Titles

Please avoid using well-known, copyrighted names like "Super Mario" or any other protected

intellectual property in your game titles. This ensures compliance with legal regulations and

minimizes the risk of copyright infringement. Instead, focus on crafting original titles that

accurately represent the unique content and identity of your game.

1.4.2 IP Infringement

It is crucial that you have the legal right to use all of the content featured in your game. This

includes obtaining permission from the owners of any brands or characters you feature. You

must be prepared to handle complaints about copyright infringement and to remove content if

necessary.

You must follow the copyright laws that apply in your country and have a process for dealing

with copyright complaints. It is important that you are able to show that you have permission

to use any content that is not yours. This helps prevent issues and delays during the approval

process and ensures that your games can be published smoothly.

If your game is rejected due to intellectual property infringement, please provide proof of

ownership or permission for the disputed content. You can submit these documents through

our contact form at Examples of acceptable proof

include

Licensing agreement

Permission letters or emails from copyright holder

Trademark registration

Any other relevant legal documentation

https://gamedistribution.com/support/.

1.4.3 Stolen games

Taking inspiration from existing games is a common practice in the current market. However,

submitting games that have been directly copied or stolen from existing titles is not permitted.

We will always give developers the opportunity to provide proof of ownership. Please note,

however, that if a game is identified as stolen, it will not be approved for publication.

1.5 Deep Fake and AI Usage

If your game, in any way, uses a deep fake content which is AI-generated or manipulated

image, audio or video content that resembles existing persons, objects, places, entities or

events and would falsely appear to a person to be authentic or truthful, you must clearly and

distinguishably explain that the content has been artificially created or manipulated along with

its artificial origin.

2. Advertising

In order to generate revenue, the correct implementation of preroll and midroll ads is

mandatory for all games. The use of display and rewarded ads is optional and recommended

to further enhance revenue potential.

You can find the implementation guide for our SDK and our rules regarding ads .here

2.1 Mandatory Ad Implementation

2.1.1 Preroll Ads

This ad type guarantees that users are exposed to an advertisement before the game begins.

Preroll ads are typically displayed following a click on the ‘Play’ button.

2.1.2 Midroll Ads

A midroll ad is an advertisement shown during natural breaks in the game, such as between

levels or after a specific amount of time has passed. Midrolls are seamlessly integrated into

the gameplay flow, and are mandatory and beneficial for generating revenue during gameplay

sessions.

Where appropriate, developers can choose to set a 2-minute timer for midroll ads. As a result,

ads are shown at appropriate intervals without overwhelming the player. The game must be

paused and muted during advertisements so that the ad can run properly and the game

progress is not affected. When the player returns from the ad, they should encounter a pause

screen that resumes only upon player interaction, allowing them to prepare for the game

again.

Implementation Guide: Check how to add the mandatory ad types .here

2.2 Additional Advertisement Options

2.2.1 Rewarded Ads

This ad type offers users in-game rewards in exchange for watching an advertisement. It is

crucial that rewarded ads are implemented correctly

–

users can only be given a reward when

an impression is completed.

ewarded ads are a highly popular ad type among users. They

enhance player engagement while also boosting game moneti

ation by offering value in

exchange for ad views.

Implementation Guide: Check how to add rewarded ads .

here

2.2.2. Display Ads

Display (banner) ads typically appear at the top, bottom, or even along the sides of a game.

However, it is important to note that the display ad must not cover any in-game content,

taking into account different window resolutions. This type of ad allows for additional revenue

without interrupting the gameplay.

Implementation Guide: Check how to add display ads .here

2.3. Ad Placement Requirements

To maintain a smooth and enjoyable gameplay experience, we recommend that ads are

displayed only during non-gameplay moments, such as between levels or during pauses.

When an ad is triggered, game audio must be muted and the game itself should be paused.

This helps prevent disjointed audio and allows for a higher CPM (Cost per Mile/Thousand)

within the game. A higher CPM means more money is generated per thousand impressions or

gameplays. Effective ad implementation is not only beneficial for the players, but also for

advertisers, resulting in higher CPMs.

The aim is to optimize player retention by controlling the frequency of advertisements.

3. Compatibility

3.1 Technology Build

Games must be built using engines such as Unity WebGL, Javascript, or Construct 2 & 3.

Games must be HTTPS ready to allow for secure content delivery. Please consult our

for more details on all applicable game engines.

SDK

documentation

We do not permit external hosting of games, except for

eal Multiplayer games. If you have a

multiplayer game, or any questions regarding a specific multiplayer mechanic, please reach

out to us for guidance.

3.2 Des

top and Bro

ser Compatibility

The game must be playable on desktop, ensuring smooth performance on popular browsers

such as Google Chrome,

irefox and Safari. Controls should be keyboard and/or mouse-

friendly.

3.3 Fullscreen and iframe

Fullscreen and iframe modes should avoid any cuts or malfunctions, and the game should

offer responsive resizing to adapt to different screen sizes. The game must adapt seamlessly

to different screen sizes and resolutions to avoid any scaling issues. We recommend using the

standard iframe dimensions of 800 (width) x 600 (length).

Please avoid the use of the Unity WebGL logo accompanied by a fullscreen option. This can

cause scaling and advertisement issues in fullscreen mode.

3.4 Mobile Compatibility

While not mandatory, we strongly recommend making games playable on as many devices as

possible. Games that are compatible on mobile devices receive priority placement with top

game publishers. Moreover, these games are offered to partners with high-traffic web pages,

such as news and media sites.

Mobile-compatible games should have smooth performance and enjoyable gameplay.

Controls need to be intuitive and touchscreen friendly. Games with a preferred orientation

should lock the user in that orientation or include a screen to instruct the user to turn the

device.

4. Localization

4.1 Default Language

For a seamless review and distribution process, the default game language should always be

English.

4.2 Expanding localizations

A game that is localized in different languages is much more likely to be picked up by our local

publishers and perform well in countries with large audiences. Consider offering your game in

multiple languages by translating buttons, instructions, and any other in-game text to boost

your distribution opportunities.

ncluding translations in the most fre

uently used languages online, such as German

)

French

(

panish

(

, and so forth, can significantly expand your game

’

s reach and

appeal to a wider audience. Please bear in mind that when including multiple languages, the

game should either detect the browser language, or give players the opportunity to choose a

preferred language before the game starts. This keeps players from being shown a tutorial or

instructions in a language they did not choose.

4.3 No-Text Option

Alternatively, you can choose to employ universal icons (Play icon, Pause icon, Home icon)

instead of text. In this case, you can select the ‘No-Text’ option instead of a specific language.

This will allow your game to bypass any language restrictions, making it more appealing for

publishers to pick up. Please bear in mind that this depends on the type of game and should

only be used if your game has no text at all.

5. Key Information

For proper integration of the game into our content management system and to ensure

visibility in our catalog, developers must provide the following.

5.1 Thumbnails

Thumbnails are a visual representation of your game and provide an important first

impression. They should accurately depict the game’s content and style. Developers are

required to submit the following thumbnail sizes: 512×512, 512×384 and 200×120

These sizes are used for our catalog, search, splash screen, and more. Therefore, these

thumbnails are mandatory. Additionally, publishers may use them on their websites.

Assets must be clear, high-quality, and unstretched. Use simple and bold graphics with good

contrast and varied colors. Logos or text are optional but appreciated, especially in larger

thumbnails. If included, text and logos should be readable, easy to distinguish, and should not

dominate the thumbnail. For more information and tips on how to create effective thumbnails,

please refer to our .Design Guidelines

5.2 Game Titles

To guarantee clarity and preserve the integrity of data within our platform, it is crucial that

game titles remain distinct. The direct duplication of existing titles is problematic and can

cause confusion among players and publishers.

5.3 Description and Instructions

The game’s description should be written in standard

nglish with correct spelling and

grammar.

e strongly recommend including details such as character names, game

ectives, the theme, and useful tips for players on how to play the game. Please keep the

use of generic words expressing excitement and satisfaction to a minimum

(

e.g. ‘awesome’,

‘amazing’, etc.). Focus instead on specific descriptors and factual information that provide

flavor, meaning, and value for players and publishers.

Consider using additional SEO optimization elements (keywords) within your description to

improve the game’s visibility in search results. In the description, use the game name (exactly

as it is written in the title) at least once.

Features should accurately describe the game’s selling points. For example, if the game is a

.IO battle royale title, consider adding key features such as

Multiplayer Pv

More than 50 weapon

More than 1 map

Instructions on how to play should be clear and easy to understand, helping players familiarize

themselves with the gameplay. Avoid using minimal descriptions such as 'Mouse' or

'Keyboard', and instead include more specific explanations. (E.g. ‘Use the WASD keys to run.’

‘Right click to shoot the bubbles’.)

The text for description and instructions should be between 200 and 500 characters each.

5.4 Genre and Tags

The selected genres and tags should accurately represent the game’s genre and content for

better discoverability. Games should have a minimum of one genre and one tag, and a

maximum of two genres and five tags.

5.5 Age Groups

It is mandatory to select the appropriate age groups for your game, as this will help to define

your intended target audience. In addition, noting specific age groups is beneficial to

publishers and their players. If applicable, it is also important to categorize your game as 'kids

friendly' or 'no blood'.

6. Credits, Outgoing Links, and Branding

6.1 Outgoing Links

An outgoing link is a hyperlink that directs users to an external website.

Games are not meant to send traffic to external websites through the use of outgoing links.

For example, a button that looks like it will start the game but instead directs the user to

another game and/or website is not permitted.

This restriction is crucial

publishers are unlikely to publish games containing outgoing links

that will direct traffic away from their website.

In other words, such outgoing links will severely restrict your game’s reach.

Here are several examples of outgoing links that we do not permit within games

Social Media Links: Links to external social media platforms such as Facebook, X,

Instagram, etc

Advertisement Links: Links to external websites or landing pages associated with

advertisements displayed within the game

E-commerce Links: Links to external e-commerce websites for purchasing products or

services

Survey Links: Links to external surveys or forms for collecting user feedback or data

Affiliate Links: Links to external websites or products for which the developer receives a

commission for referrals

Content Sharing Links: Links for sharing game content or achievements on external

platforms.

6.2 Branding in Your Game

You are allowed to display your brand name or logo in the loading screen, main menu, or even

on a separate credits page within the game

However, any branding elements within the game must not refer the player to an external site,

as clickable outgoing links are not permitted. Please do not include any contact details or

referrals to social media pages within the game.

6.3 References to App Stores/PlayStore

References to your game’s AppStore or PlayStore are not permitted within the game itself.

These and other references can be submitted as links in the Backlinks tab of your game’s

individual catalog page.

7. Personal Data

Any collection or storing of data from a game is strictly prohibited. In addition, any types of

cookies or trackers that are not directly from GD will not be permitted. Login requirements are

not permitted unless permission is granted for this under a separate agreement.

Trackers, in this context, could refer to a standard link that has parameters attached to it for

the purpose of tracking and analytics. Examples of trackers we do not permit include:

Google Analytics: A widely used web analytics service that tracks and reports website

traffic

Facebook Pixel: Tracks user interactions with Facebook ads and measures their

effectiveness.

DoubleClick by Google: A digital advertising platform that tracks user interactions with ads

across different websites

Flurry Analytics: Provides analytics for mobile applications, tracking user behavior and app

usage

Mixpanel: A business analytics service that tracks user interactions with web and mobile

applications

Adobe Analytics: Offers real-time analytics and detailed segmentation options for tracking

user behavior
