URL Snake — Play Classic Snake Game Directly in Your Browser’s Address Bar

The Hook: A Game You Can See in Your URL Bar

Ever wanted to see a game appear in your browser’s address bar? With URL Snake, you can. Open a link, and within seconds a classic Snake game materializes, letting you play with the URL itself. No downloads, no accounts, no setup — just pure, instant fun. The URL Snake game uses Unicode Braille characters to render the snake and food directly in the address bar, creating a visually striking experience that surprises users in seconds [S1][S2].

This project demonstrates the surprising power of modern web browsers. The snake game isn’t running in a separate window or tab — it’s actually rendering within the address bar itself, using Unicode Braille characters to draw the game board. You’ll see a snake made of interconnected dots moving through a grid, with food items appearing as single Braille characters. When the snake hits the edge of the grid, it’s game over.

This is the kind of unexpected browser magic that makes web development so fascinating — taking familiar elements like the URL bar and transforming them into something delightfully different.

At a Glance

  • Grandma-test difficulty: Tier 1 — Instant Click (open link, zero install, result in under 60 seconds)
  • Try-it time: Under 60 seconds
  • Worth your time? Yes — a quick, satisfying creative burst that sparks curiosity and delight

What You Need

A modern web browser (Chrome, Firefox, Safari, or Edge) that supports the URL bar modification technique used by this game. That’s it. No accounts, no installations, no special software. The game runs entirely in the browser, powered by pure JavaScript, with zero external libraries or dependencies [S1].

The project is open source and has been actively maintained since its creation, with the source code available under a permissive license on GitHub [S1]. The entire game logic is contained in a single HTML file that can be opened directly, making it exceptionally portable and easy to understand.

Simple Setup Walkthrough (3 Steps)

  1. Open https://demian.ferrei.ro/snake in your browser. If you have a URL bar, type the address and press Enter. The page will load with initial game state [S1].
  1. Click the address bar to focus it, then press Enter to launch the game. This action updates the URL with the initial game state, which the page renders visually using Unicode Braille characters [S2].
  1. Play! Use the arrow keys to steer the snake, which grows as it eats the food. The game ends when the snake hits the edge of the URL bar or itself. The entire experience happens within a single browser tab, with no installation or configuration required [S1].

The beauty of this project is how little friction there is between you and the experience. Within 30 seconds of clicking the link, you’re already playing a fully functional Snake game rendered in your browser’s address bar.

First Thing to Try

Open https://demian.ferrei.ro/snake, click the address bar, and watch the game instantly appear. Use the arrow keys to control the snake and watch it grow as it eats the food. Try to survive as long as possible without hitting the edges or yourself — that’s the classic Snake challenge in its purest form [S1][S2].

Notice how the Braille characters create a pixelated look that’s both precise and charming. Each section of the snake is a single Braille dot character, and when they connect, they form the impression of a continuous body. This is the kind of elegant simplicity that makes open-source projects so educational.

Turn It Into a Challenge

  • Challenge 1: Try to get the snake to eat 10 pieces of food without hitting the edges or itself. Can you set a new personal record?
  • Challenge 2: Change the URL to a different domain (e.g., https://example.com/snake) and see if the game still works. Does the rendering change?
  • Challenge 3: Share your URL with a friend and see who can survive the longest. You can compare scores instantly using the URL state.

These challenges extend the basic experience without requiring any code changes or installations. They encourage exploration and discovery, which are hallmarks of good beginner projects.

Optional Expert Rabbit Hole

For those curious about the implementation details, examine the source code on GitHub (epidemian/snake). You can see how the game parses the URL, converts coordinates to Braille-like symbols, and renders the game in real-time using only JavaScript [S1].

The game uses a clever technique where each position in the grid maps to a specific Unicode Braille pattern. By setting individual dots within these patterns, the snake and food can be rendered pixel-perfectly within the constraints of the URL bar. Advanced users could experiment with modifying the character set or adding new game mechanics.

The classic Snake game has a rich history, originally popularized on Nokia mobile phones in the 1990s and 2000s, before evolving into countless variations across different platforms [S3]. URL Snake captures that nostalgic feeling while showcasing modern web capabilities.

One Thing to Know

The game uses the browser’s address bar, which some browsers restrict for security or usability reasons. You may need to manually type the URL instead of using the address bar’s copy-paste function in some browsers [S1][S2]. The game also uses Unicode Braille characters that may render differently depending on your browser and operating system, so the visual appearance might vary slightly.

Bottom Line

A perfect Tier 1 B.Y.E. project: instant click, visible delight, zero friction, fully interactive, and beginner-safe. Open the link, click the address bar, and start playing in under a minute. This is the kind of project that proves the web is still full of delightful surprises waiting to be discovered.
