About the Chrome Dino T-Rex Endless Runner
Created by the Google Chrome team in 2014, the 'No Internet' Dinosaur Game (codenamed Project Bolan after Marc Bolan, lead singer of the 1970s glam rock band T. Rex) was introduced as a playful Easter egg for users who lost their internet connection. Our web-based edition recreates the authentic mechanics while introducing switchable pure white and dark arcade themes, variable jump heights, synthesized retro sound effects, and persistent local storage high scores.
How to Use
- Press Spacebar, Up Arrow (↑), or W to jump over small, large, and clustered cacti.
- Hold the jump key longer to leap higher over tall obstacles, or tap lightly for quick micro-hops.
- Press Down Arrow (↓) or S to duck underneath flying pterodactyls (or drop quickly when in mid-air).
- Toggle between White / Light Mode and Sleek Dark Mode using the Sun/Moon theme button.
- Toggle synthesized 8-bit retro sound effects using the sound icon.
- Press P anytime to pause and resume your run.
- On smartphones and touchscreens, tap anywhere to jump, or use the on-screen Jump and Duck buttons.
Key Features & Benefits
- Switchable White & Dark Themes: Play on a crisp, clean white background like the original offline daytime desert, or switch instantly to a modern dark theme to reduce eye strain in low-light environments.
- 100% Client-Side Web Audio API: Audio synthesis generates authentic 8-bit square and sawtooth waves dynamically in your browser without requiring external audio file downloads.
- Dynamic Variable Jump Physics: Features responsive jump physics where releasing the spacebar early cuts your vertical velocity for precise timing over staggered obstacles.
- Local High Score Persistence: Your personal best score is saved automatically to your browser's local storage so you can come back and beat your record anytime.
Frequently Asked Questions
How do I play the Chrome Dino game?
Simply press Spacebar or Up Arrow on your keyboard (or tap the canvas on mobile) to start running. Jump over oncoming cacti and duck under flying pterodactyls. The game speed gradually accelerates as your score increases.
How does the variable jump mechanic work?
Holding down the Spacebar allows your T-Rex to reach maximum jump height, which is essential for clearing large cactus clusters. Tapping the key lightly triggers a short hop, perfect for landing quickly between tight obstacle gaps.
When do flying pterodactyls start appearing?
Pterodactyls begin appearing once your score reaches 250 points. They fly at three different altitudes: high (which you can run under), medium (which requires ducking), and low (which requires jumping).
Does this game require an active internet connection?
No. Once the web page loads, the entire game engine, sprites, sound synthesizer, and physics execute 100% locally in your web browser with zero server communication.
