Racer Snake takes a familiar idea and tunes it until it clicks. Here you get a starting step of 110 ms that tightens as you eat, wrapped in a clean, distraction-free board that works just as well on a phone as on a laptop.
Big scores come from patience, not speed - hug the edges, keep escape lanes open, and only cut across the middle when the pellet is worth the risk. It is a game about not panicking, dressed up as a game about eating.
Nothing here needs a tutorial or a wiki. Controls are one gesture, the goal is one sentence, and the difficulty comes from execution rather than homework. That is exactly what a browser game should be.
Grow the longest snake without touching walls or tail.
