Snake Dense is a browser game built for short, satisfying sessions - it loads instantly, plays with one thumb, and runs on any mid-range phone. The setup is simple: a starting step of 150 ms that tightens as you eat. Nothing to install, no account, no waiting.
The snake moves in fixed steps; each pellet eaten adds length and slightly tightens the interval, so the game gets harder the better you do. Walls and your own tail both end the run instantly. The a starting step of 150 ms that tightens as you eat, and the ramp is tuned so mid-game still feels fair.
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.
