Those who are new to this market might need help with finding popular games among their competitors for their portal, as well as information on how to check their quality, what services are available for these games, what payment choices are available, and even be aware of the legal implications before purchasing it. If you fall into this category as well, there is no need to worry.

In this article, I’ll detail these topics so you can learn how to prepare a game for your game portal.

First Step, Finding the License Providers

Preparing a game for your portal is a process, and as with all processes, there is a starting point. As previously said, there aren’t many reputable HTML5 game license providers. Due to their scarcity, picking the right provider can be crucial. So your first step should be looking for companies that provide HTML5 game licenses. Of course, I’m talking about games made with great care and attention to detail.

Otherwise, a quick search will turn up a lot of inexperienced developers with games that aren’t really entertaining or interesting. I do not recommend this method because it can damage the quality and credibility of your portal.

Thankfully, there aren’t many high-caliber license providers in the HTML5 games market. I’ve highlighted a few of these experienced companies who give exceptional service and support below:


DoonDookStudio, which was founded in 2018, has grown to become a top-tier HTML5 game license provider by following market trends. DoonDookStudio currently offers over 120 high-quality games, as well as a wide range of services and purchasing options.


To boost customer appeal and engagement, DoonDookStudio offers premium HTML5 games, services, and licenses to online game portals, P2E platforms, non-gaming platforms (such as well-known apps and In-flight Entertainment Systems), and VASs.

One of DDS’s unique traits is its ability to strike a balance between price and quality; as a result, all of this provider’s products are priced in accordance with the level of quality.

DoonDookStudio’s main features are as follows:

  • HQ HTML5 Games: DoonDookStudio (currently) features more than 120 high-quality games for both gaming and non-gaming portals and platforms.
  • Game Design for Game Portals and Non-gaming Portals: DoonDookStudio provides HTML5 games of the highest quality, for both game portals and non-gaming portals (like IFE).

The following are CodeCanyon’s top features:

  • Different Prices, Varying Qualities: As previously noted, CodeCanyon is a marketplace for digital assets. It offers a vast selection of HTML5 games with no set pricing range. The reason behind this is that different developers determine differing pricing.
  • Huge Selection of Games: CodeCanyon features over 5100 HTML5 games made by their international community of independent developers. As CodeCanyon states, reviews all the submitted games by its staff.

Testing Out the Games

Knowing the license providers is not enough. After visiting the website and reviewing the histories of each of these providers, you should spend some time evaluating their games.

Testing the game

On the provider’s website, you can choose any game you like or deem necessary for your game portal and then asses their quality by running and playing them for some time. (which includes graphics, music, gameplay, etc.).

In general, you should keep the following in mind when testing games:

  • Does the user get enough training tips when they first start the game?
  • Are the earlier levels easier than the subsequent ones?
  • Does the game’s difficulty increase as the player’s skill level rises?
  • Does the user get help or rewards when they need it?

What Are the Features of Profitable HTML5 Games?

Below are the features you should be looking for when testing the games:

  • Built by Popular and New Technologies: Using new technology means having access to many popular video game engines and frameworks, easier hiring of technical expertise, and reduced costs.

  • Fast & Flawless Run: It indicates that a game functions well and without any issues. Its indicators are the responsiveness and polish of the games.

  • Low Size: Since page loading speed is very important, you should think about the game’s file size when choosing one so that it doesn’t slow down your website’s loading speed.

  • Eye-catching Graphics: The graphical quality of a game conveys one message: This game is worth your time. Graphical quality greatly impacts users’ desire to play the games.

  • Appealing Gameplay:  Try out the game and make sure that its gameplay is fun enough for your audience.

  • Quality Store:This item is optional in every game, and its absence has no impact on the gameplay. However, if there is a store, users can collect coins or points to customize the game’s settings, utilize various game objects, etc. The store persuades users to continue playing and makes them experience less monotony in the game.
  • Game Balance: Balance refers to the quality of level designing and its gradual difficulty. When testing, you should keep these in mind:
  • Does the player receive enough tutorials?
  • Does level difficulty increase as the player becomes more skilled?

However, the list of pre-purchase considerations does not end with these. To learn more about the important features to look for when purchasing a game, I suggest you read the ‘7 tips for buying profitable games‘ article.

What Are HTML5 Game Services?

Depending on their business goals and the way the technology is set up, game producers need different services for the HTML5 games they purchase. License providers offer these services alongside their games. Each of these services will be briefly explained below:

White Label
Game Reskin
API/SDK Implementation
FB Instant Games
Game Localization

White Label Service

For game portal managers, white labeling is one of the most essential services for businesses to monetize through HTML5 games. They use HTML5 games that feature their brand and logo, which another party has developed. The developer can do any customization and implementation the clients prefer. Still, the final product’s name of the HTML5 game belongs to the business that purchases the game.

Assume you want to publish your desired game under your brand name, emblem, and logo, but the game’s producer is another entity. To accomplish this, you’ll need the white label service. The white-label service allows you to present your desired game to your players and customers under your company’s brand.

In other words, the retailer uses its name on the products to stand out, but the product’s producer is another entity.

Game Reskin Service

You may need a unique game for your online game portal, a short-term campaign, or FB instant games, or you may prefer, for commercial reasons, that the game be prepared with a unique theme and visual elements for your business brand. For instance, you might prefer to switch the game’s theme from the desert to the beach. This is where reskin service can help.

Reskin means modifying the skin or shell. It entails making several changes to the game’s appearance, but with restrictions and within a specific framework.

What Does Reskin Service Include?

  • Theme and Graphics: It entails redesigning the game with the theme and visuals chosen by the customers. Publishers are typically interested in featuring games that cater to the preferences of their target audience. It can be the theme of a particular season or even a special occasion.
  • Sound and Music: This service involves changing the audio and soundtrack of the game to fit the experience. It ensures that the user receives a genuine sense of the ambiance and experience of the game.
  • Minor Gameplay Changes: Sometimes a client needs minor adjustments to the game’s rules or gameplay or even a new option to be introduced to the game’s features. Of course, these modifications don’t change the game’s rules, and the game’s source doesn’t undergo significant changes.

It’s also worth mentioning that since developing an exclusive game from scratch is very costly (around  $7000 to $20,000 each), reskin service is a cost-effective solution for obtaining the game that portal managers desire.

Game Localization Service

Game localization is the process of converting the existing content to a new target locale, both linguistically and culturally.

Game Localization For the benefit of your international target audience and to enter other HTML5 game markets, you as a portal manager might occasionally want to optimize a particular game for a specific geographic region with the local language, culture, music, and other elements of that region. That’s where the game localization service comes in handy.

Game localization has numerous benefits, which among them is the cultivation of a stronger sense of empathy with players, which can increase user engagement, loyalty, and sharing rate.

What Are the Essential Aspects of Video Game Localization?

  • Visual & Graphical Elements: Adapting all visual elements, characters, etc. to the target region’s culture
  • Textual Elements: Idioms, dialogue, subtitles, guides, instructions, and tutorials are all translated so that they convey the same message in both languages.
  • Audio Elements: It includes modifying the game’s soundtrack, music, sound effects, and voice-overs to the target region’s preferences. For example, changing the game’s audio to fit the target audience’s cultural standards.
  • Regional Format: It entails translating regional formats such as date, time, metrics, and so on. For example, change the metric Kilometer per hour (kmph) to Mile per hour (mph).

Implementing API/SDK

It’s common for customers to request technical adjustments for the games they purchase. They often ask for in-game technical modifications like implementing an API, SDK, leaderboard, etc. Generally speaking, API/SDK implementation service establishes a connection between the game and the client’s server.

Several communication models between the game and the server are as follows:

  • In the game, once the player obtains the score, the game sends it to the server so it can be stored in the client’s database. At the end of the game, the game requests that the server send the information of the top ten players with the highest scores to the game so it can be displayed.
  • Suppose in a multiplayer board game, players can ask the server for the rules of that game (for example, the number of players eligible to play).
  • Imagine a client has an app with several games. When the player loses after playing for a while, the game notifies the server that the game is over and that it is time to quit the game and return to the home page.

Depending on the technology you use, the API/SDK implementation service will use various techniques and technologies to communicate with the server and the game. You can implement some of these technologies, such as AJAX, which offers non-persistent communication, or Websocket, which offers persistent communication, depending on your requirements.

FB Instant Games

Facebook Instant Games is a relatively new gaming platform that may be used on computers and mobile devices running Android and iOS.

FB Instant Games

It is supported through the applications that Facebook offers, such as Messenger.

Instant Games are games that may be played directly in a user’s Facebook News Feed. They allow gamers and their friends to immediately begin the action. These games need no download time. All you have to do is start playing.

With FB Instant Games service, the customer’s preferred game can be published on the FB Gaming platform. The goal of doing this is to publish the game on one of the most populous social media platforms. Also, to reach a huge audience and increase profits.

What Are the Benefits of Using This Service?

  • The Facebook User Base is Enormous: There are more than 3 billion users on this platform, and millions of them play FB instant games daily.
  • Easy Game Sharing Will Help Your Game Grow: Using this feature, Facebook users can share your game on their timelines or through Facebook messenger with friends, acquaintances, and coworkers.
  • Having the Option to Compete with Other Users: Users can engage in real-time or score-based competitions on this social platform.
  • Bringing Back the Players Through Notifications: This feature enables the publisher to entice users to come back and play more of their game by sending Facebook notifications.
  • Facebook Click-To-Play Ads: Facebook allowed easy game publication inside its vast community. It didn’t stop there and provided different groups of users with C2P advertisements. Which is a brilliant encouragement to attract users.



One way for businesses is to significantly boost income through in-game ads, and providers offer this service based on your preferences. With the large number of businesses that offer gaming advertisements, it is impossible to list all of their products and advertising strategies here. However, the following models are often used:

  • Banner Ads: the fixed or dynamic display of a banner ad at the top or bottom of the screen
  • Interstitial Ads: A full-screen ad usually displayed between game sessions (like at the end of a level), which can be an image or a video.
  • Rewarded Ads: an ad (usually a video) that is displayed to the user in exchange for a reward. After the complete presentation, the user receives a reward.

As mentioned, many businesses offer advertising for games, but the most famous of these providers include:

  • Admob: It’s an ad service from Google used for mobile applications and games.
  • Adsense: It’s an advertising service from Google that is usually used for websites. However, you can also implement it directly in the games.

You may have a direct relationship with advertising providers and require the advertising service to use in games through your API (as your interface in the game). In that case, you can ask the license provider (if they do that) to do the job for you.

Purchasing Options

Once you’ve decided on the game and the changes you want to make, it’s time to look into your purchasing options. Generally, HTML5 game license providers often sell game licenses in one of three ways:

  • Single Purchase: As the title suggests, a single purchase means paying the full price for a single game, typically without a discount.
  • Bundle Purchase: Sometimes, providers put several games with common features (top Facebook games, best-selling games, etc.) as a bundle for customers. From the customer’s point of view, this is the best and most cost-effective purchase method.
  • Bulk Purchase: Bulk order means that a customer gets a bigger discount for the more games he buys. After purchasing in bulk, this option is also preferable and more economical than a single purchase.

Legal Tips

You might believe purchasing a game with appealing gameplay and visuals is sufficient for obtaining a game license. However, the truth is that as a publisher or manager of an HTML5 game portal, you should be aware of a number of legal issues before purchasing the game.

Legal tips

If you don’t, you might be unable to fix them after purchase, which could cause serious financial, legal, and reputational damage to your business.

In any case, you should pay close attention to the credentials of the provider, the rights to use the game license, the contents of the delivered file, support, and copyright regulations. Therefore, I recommend reading about HTML5 games’ legal implications before purchasing any HTML5 game.
