Browser games are interactive digital entertainment that runs directly in a web browser and does not require the installation of separate programs. Thanks to the use of standard Internet technologies, such games are available on most devices — from personal computers to smartphones — as long as they have a browser and Internet access.

HTML5, CSS3, and JavaScript form the foundation of the modern browser gaming industry. HTML5 played a particularly important role, as its emergence gave developers the

Depending on the technologies used, browser games can be divided into several categories:

  • HTML5 Canvas + JavaScript — the best option for 2D games with good performance but limited 3D capabilities.
    Examples: Agar.io, Slither.io
  • WebGL — provides three-dimensional graphics and hardware acceleration, but requires more in-depth knowledge of mathematics and working with shaders.
  • Examples: Quake JS, Sketchfab
  • CSS3 + JavaScript — a simple approach for creating simple games and puzzles, but with limited performance.
    Examples: 2048
  • WebAssembly — allows you to achieve near-native execution speed and use languages such as C and C++, although the technology is still considered complex and relatively new.

Examples: Unity WebGL projects, Doom 3

Modern browser games have a wide range of capabilities:

  • a single code base for different platforms;
  • support for real-time multiplayer modes via WebSockets;
  • access to device hardware features (camera, microphone, sensors);
  • offline mode thanks to Service Workers and local storage;
  • a variety of monetization models — from advertising to subscriptions and in-game purchases.

Today, browser games cover almost all genres: from simple logic puzzles to large-scale strategy and RPG games. The limitations that previously held back the development of web gaming are gradually becoming a thing of the past, opening up opportunities for increasingly complex and ambitious projects.
