Snake

Snake is the arcade classic distilled to its essence: steer a snake around a grid, eat the pellet, grow one cell longer, and never touch your own body. Every pellet raises your score and slightly raises the pace, so a comfortable run never stays comfortable — the game you survive is faster than the game you started.

This version respects the device you are on. On touch screens you steer with swipe gestures or an on-screen D-pad; on a keyboard, arrow keys and WASD both work, and Space or P pauses. Two rule variants are a toggle away: deadly walls for the traditionalist, or wrap mode where the edges teleport you across the board — the same hunger, a completely different geometry.

The game is honest about attention. Switch tabs or lock your phone and it pauses itself instantly; the fixed-timestep loop clamps every frame, so a throttled background tab can never run the snake into a wall, inflate a score, or hand you an unfair death on return. Resume exactly where you left off.

Your best score, speed and wall-mode preferences and a play counter live in your browser's local storage — no account, no server, nothing leaves the device. The engine itself is pure and deterministic: the game loop owns only the clock, and stepping, eating, collisions and food placement are plain functions with injected randomness.
