Gemini's New Checkpoint Builds a Smooth 60fps Rainbow Snake Game in One HTML File
Last_Conclusion_8984 · reddit · 2026-09-17
A Reddit user tested the newest Gemini 4 pro checkpoint, calling it unusually "vibrant and creative," and shared the full prompt used to generate a complete Snake game in a single HTML file. The prompt enforces a fixed 10-ticks-per-second logic loop with a locked 60fps render loop and frame interpolation so the snake glides between cells, plus rainbow HSL color cycling, neon/CRT aesthetics, pause and restart controls, touch support, and localStorage high scores. The author argues "a prompt is the steering wheel, not the driver" and invites testing the same prompt on other models.
