Why Use an HTML5 Game Template?

Building a game is difficult. With several distinct skill sets nestled into a complex package, it can be difficult to start a whole project from scratch.

For those new to game programming, using a game template can help to fill in those gaps in skills, such as user interface or graphic design, giving insight into the workings behind a completed game. This is a great learning experience and helps you get your first couple of projects done without getting too overwhelmed.

Experienced game programmers can find plenty of use from these game templates too. They can help to build the skeleton for a larger game or act as the base for a new project, cutting down on creating repetitive code for each new game you make.

Designing Online Games

So you have an idea for an online game or several. But how do you start building one?

You can build a game from scratch. It requires you to have a knowledge of programming. If you don't know how to code, you can use templates. There are thousands of them.

But either way, you have to have a roadmap. Have a basic and detailed description of:

  • What kind of game do you want to create?
  • What is your game about?
  • In what genre?
  • For what platform: is it a mobile game (iOS or Android) or a desktop game (Windows or Mac)?
  • How do you want it to look?
  • What visual features do you want to include?

In addition, some game design software allows you to build games with drag-and-drop—without even knowing how to code!

Drag-and-drop game making software includes:

These platforms all have free versions that allow you to publish to the web, but you'll need to pay for professional editions that allow you to make mobile games.

Text-Based Game Engines

The most basic game design software allows complete beginners with no coding experience to create text-based games. Quest is the perfect beginners' software, and so is Twine.

Create 2D Games Without Coding

To create 2D games you can use Stencyl, Game Maker, or Construct 3. These are beginner-friendly, with no coding experience needed, and they have drag-and-drop interfaces.

Choosing Game Design Software

  1. Choose software that publishes to HTML5 and is oriented to publishing games in mobile browsers. You don't want to miss out on mobile users.
  2. If you want to make money as a game designer, think of software that comes with end-user data collection and game monetization choices.
  3. It should be easy to use and come with extensive documentation and tutorials.
  4. It should have access to a robust community of users sharing technical knowledge.
  5. It should also come with a rich library of stock images and stock music.

Publishing and Distributing Your Game

Option 1: Distribute and Host Your Game Independently

To distribute independently, you will need a hosting service with a reliable infrastructure that can handle a lot of traffic and also make your game website available at lightning-fast speeds. Of course, you'll pay a lot in hosting fees. You will also need to build and maintain a vibrant online community in order to be profitable.

Option 2: Outsource Hosting and Distributing to a Gaming Platform

Platforms offer a ready-made audience through their vibrant built-in communities. Keep in mind they do charge submission fees for each game you submit. They also charge a percentage for every sale.

To outsource the hosting and distribution, you can use the following platforms:

  • Android: Google Play Store or Amazon Appstore
  • iOS: App Store
  • Desktop and Mobile apps: Steam, Game House, Gamers Gate, Humble Bundle, Kongregate, Gog,
