About Cyber Dash
Cyber Dash is a one-button endless runner generated with Google AI Studio, and it distills the genre to its purest, most addictive form. Your character auto-runs through a synthwave landscape — dark sky, glowing horizon, parallax mountains scrolling past. Obstacles appear ahead; you jump. That is the entire control scheme, and it is all the genre has ever needed. Tap, click, or hit space to jump, with a double jump available for the gaps that look impossible until you trust it.
What separates a good runner from a great one is the difficulty ramp, and Cyber Dash was tuned hard on exactly that axis. Speed increases steadily as you survive, and the obstacle density rises with it — but the spawner guarantees a fair minimum gap, so every death feels earned rather than cheap. The distance counter climbs in the corner of the screen, quietly daring you to beat it. Runs last anywhere from 20 seconds to a triumphant few minutes, and restarting is one tap. It is the archetypal one-more-try game: the entire Daily AI Games team has lost lunch breaks to it.
The game works identically on phone and desktop. On mobile the whole screen is the jump button, with the lower half as a forgiving thumb zone; on desktop, space or a click does the job. There is no tutorial because none is needed, no account, and no download — like every game on this site it runs straight in the browser as a single HTML file.
Cyber Dash is also a peek into how AI handles procedural systems. The obstacle spawner, the parallax rendering and the speed curve were all produced by Gemini from a structured prompt that explicitly demanded "never impossible" pattern generation — and it mostly held to the contract. You can read the full prompt in our prompt library, and the tool write-up explains why AI Studio is our default bench for this kind of procedural experimentation.
How This Game Was Generated
Generated with Gemini 3 in Google AI Studio using our endless runner prompt, which pins down the speed ramp and the fair-gap rule. Two iterations fixed an edge case where double-jumping over tall obstacles felt inconsistent. The parallax background was a follow-up prompt.
The Prompt Behind This Game
Show the prompt used to generate Cyber Dash
Create a complete one-button endless runner in a single self-contained HTML file (inline CSS/JS, no libraries, no external assets). Core spec: - The player character auto-runs; a single input (tap / click / spacebar / up arrow) makes it jump. Double jump allowed once per airtime. - Obstacles spawn off-screen right and scroll left with increasing speed. Mix low obstacles (jump over) and gaps/holes (jump across). - Score increases with distance; show best score of the session. - Difficulty curve: speed increases ~8% every 10 seconds, capped at a sane maximum; obstacle density ramps with speed but never creates impossible patterns. Guarantee a fair minimum gap between obstacles. - Ground collisions use simple AABB checks. One hit = game over overlay with score + restart on tap. - Visual style: [describe, e.g. "a dark synthwave desert with parallax mountains"]. - Must run at 960x540 internal resolution, responsive and letterboxed; must work with touch on mobile. After the code, briefly explain your difficulty-ramping rules so a designer could tweak the numbers. Fixed tuning numbers: 240 px/s base speed, 320px guaranteed minimum gap between obstacles, double jump at 85% of full jump impulse.Open in the prompt library for tips and variations
