Snake: Still the Best Difficulty Curve Ever Designed 🐍

The rules

You control a snake moving continuously around a grid. Steer with swipes or arrow keys. Eat the apple to grow one segment and score. Hit a wall or your own body and it's over.

Coiling: how to survive the late game

Early on you can chase apples directly. Past about thirty segments, direct routes start trapping you — you reach the apple and discover your own tail has sealed the exit.

The fix is to stop thinking about the apple and start thinking about the shape of the space you're leaving behind.

Hug the edges. A snake coiled around the perimeter leaves one large connected open region in the middle. A snake wandering through the middle cuts that region in two, and half of it becomes unreachable.

Follow your own tail. If you're stuck for a safe move, trailing your own tail is always survivable — the tail moves away as you advance, so the cell is free by the time you reach it. It buys time until the next apple spawns somewhere reachable.

Take the long way. When an apple is two cells away but taking it seals you in, take the twelve-cell route instead. There's no time pressure in Snake; the only thing that kills you is geometry.

Serious players go further and follow a Hamiltonian cycle — a fixed route through every cell that can never self-intersect — which is unbeatable but takes the fun out of it.

Why the design still works

No lives, no upgrades, no ramp designed by anyone. The game has one variable, your length, and it's the same thing as your score. That means the challenge is always exactly calibrated to how well you've been playing, which is a property most games spend enormous effort faking.

Questions people actually ask

How do you get a high score in Snake?
Stay near the walls so the open space stays in one connected piece, follow your own tail when you have no safe move, and take longer routes to an apple whenever the short one would trap you.

Can Snake be played on a keyboard?
Yes — arrow keys or WASD on desktop, swipes on touch.
