How to Beat Your Snake High Score

Snake rewards discipline and geometry. Here is the guide that helped us triple our scores.

The casual version of Snake feels like a reaction game, and for the first 30 points it is. But past 50 points, the snake is so long that reaction time is no longer the bottleneck — geometry is. Your real enemy is your own tail, and the only way to stay alive is to plan the snake's body to match the shape of the board.

Phase 1: the early game (0-30 points)

In the early game, the snake is short and the board is mostly empty. Your job is simple: eat the food before it moves, and don't paint yourself into a corner. Try to keep the snake's head near the centre of the board so that you have room to turn in any direction.

A useful trick in the early game is to always approach food from the direction that leaves you with the most open space after eating. If the food is in the top-left corner, approach from the right so that after swallowing it you can swing downward into open territory rather than getting stuck in the corner.

Phase 2: the mid game (30-80 points)

Around 30 points the snake becomes long enough that you cannot freely cross the board without risking a self-collision. This is where most players die. The mid-game strategy is to commit to a spiral pattern or a boustrophedon (the "ox-plow" zig-zag pattern).

In a spiral, you move around the outside of the board in a consistent direction — say clockwise — and each lap spirals one row inward. This guarantees that your body is always parallel to itself, which means you cannot accidentally cut off your own head. Once the food appears inside the spiral, you break the pattern just long enough to collect it, then return to the spiral.

Phase 3: the late game (80+ points)

In the late game, the snake fills a large fraction of the board and the safe moves are few. The key insight is that you can treat the remaining empty cells as a Hamiltonian cycle — a loop that visits every empty cell exactly once. If you follow a Hamiltonian cycle, you literally cannot die, because you will never re-enter a square that contains your body.

Obviously, strictly following a Hamiltonian cycle is slow (it takes N moves to eat a single food on an N-cell board). Skilled players take shortcuts when the food is close, reverting to the cycle when the board gets tight.

Specific techniques

  1. The hug. In narrow corridors, keep the head adjacent to the wall rather than the centre. This gives you one less direction of potential self-collision.
  2. The fake. When two pieces of food appear, approach the first in a way that naturally lines you up for the second.
  3. The pivot. Halfway through a run, when your spiral is running out, pivot to the opposite corner and start a new spiral there. This resets your effective board size.
  4. The wall-cycle. Going around the perimeter is always safe as long as the snake is shorter than the perimeter. Use it as your "home" move when in doubt.

Speed settings

If the game allows you to choose a speed, beginners should stick with medium. Fast speed multiplies every mistake; slow speed makes you impatient and sloppy. Medium hits the sweet spot where decisions feel meaningful without punishing every fraction of a second.

Common mistakes

  • Chasing the food head-first. The food isn't going anywhere. Plan the shape of the approach.
  • Over-correcting. If you make a small mistake, do not panic-turn. Breathe and make a clean compensating move.
  • Ignoring the tail. Your tail is a moving wall. Predict where it will be in three moves, not where it is now.
  • Playing too fast. Speed tempts sloppiness. Slow down.

Score milestones

For a 20×20 board, score milestones you can aim for:

  • 30 points: casual player.
  • 60 points: above average — you can execute one clean spiral.
  • 100 points: strong player — you can manage mid-game turns.
  • 150 points: expert — you have internalised the Hamiltonian cycle.
  • 200+ points: you have basically solved the game.
