A modern 3D take on the classic Snake, built with Unity 6 and the Universal Render Pipeline. Guide your snake around a walled arena, eat the food to grow longer, and weave between the spikes for as long as you can survive.
- Grow longer — 1–2 pieces of food are on the board at any time; eat the last one and a fresh batch appears, always on a free tile.
- Dodge the spikes — hazards are scattered across the arena at the start of every run (never near your spawn, and never under food).
- Don't crash — hitting a wall, a spike, or your own body ends the run: the snake turns black and collapses onto the board, and you can restart instantly.

Snake at length 13, threading between spikes:
Game over — the snake collapses where it crashed:
The game logic is fully grid-based — the snake is a list of integer cells, and movement, wall hits, self-collision, food pickup, and spike hits are all resolved with cell math. No Rigidbodies, colliders, or physics callbacks are used during play, which makes the gameplay deterministic and frame-rate independent. Physics is added only at the moment of death, purely for the collapse effect.
| Script | Responsibility |
|---|---|
GameManager |
Game state (playing / game over), score, and end-of-game UI. Self-creating singleton — no scene setup needed. |
SnakeMovement |
The snake itself: buffered input (no 180° reversals), fixed-interval stepping, growth, and all collision checks. |
GenerateFloor |
Builds the checkerboard floor and border ring, and defines the playable bounds everything else reads. |
GenerateFood |
Keeps 1–2 foods on free tiles, spawn area derived from the floor bounds. |
GenerateSpike |
Scatters spike hazards on free tiles at the start of each run, with a safe zone around the spawn. |
Events |
UI button handlers (restart, menu, quit). |
