The Snake high-score routine
Here is the pattern we noticed while testing our own Snake board. Sit somebody down for ten runs and the scores come out looking like 7, 9, 6, 31, 8, 11, 5, 9, 12, 7. There is always one run that stands out, the player always remembers it, and they almost never repeat it. The 31 was not a better player. It was the same player getting a run of food that happened to appear in front of the head instead of behind it.
Everything below is about deleting that variance. None of it is a trick or a glitch. It is a way of moving that keeps your own body in shapes you can still get out of, so a good spawn sequence becomes a bonus rather than the whole run.
Why the scattered run always ends the same way
Untrained Snake is played as a series of errands. Food appears, you point the head at it, you take the shortest route, you collect it, you repeat. Nothing about that is wrong for the first ten pieces. The problem is what it does to the shape of your body over time.
Every errand leaves a curve behind. Ten errands leave ten curves crossing the middle of a 24 by 24 grid at unrelated angles, and the free space between them is a set of narrow, irregular corridors that you did not plan and cannot picture. You do not die because you made a bad turn. You die because forty moves earlier you started building a maze and never looked at it.
Notice too that the difficulty is entirely self-inflicted. The board never adds obstacles. The snake is the only thing in the way, which means the shape of the board is the one variable you have complete control over.
The comb: stop travelling to food, let food come to you
The fix is to give the snake a default route it follows when nothing urgent is happening. The route most players converge on looks like a comb.
Run the head up the full height of a column until you reach the row below the top edge. Step one square sideways. Run the full height back down the next column. Step sideways again. Keep going until you have swept the board from one side to the other, then start again from the far side. The top row (or the bottom, depending on which way you set it up) stays clear as a return lane.
Three things happen when you play this way:
- Food stops being a destination. Anything that spawns in the columns ahead of you gets collected on the way past for zero extra distance. You are not making trips any more, you are running a route that happens to pass over food.
- Your body becomes parallel lines. Vertical strips are the one shape you can look at once and understand completely. There is nothing to trace, nothing to guess at.
- You always know where the exit is. The lane at the end of the sweep is always open, because you built the pattern around keeping it open.
Set this up on purpose at the start of a run. From the opening position the snake is three segments long, moving right, sitting in the middle of the board. Take it to a corner first and start the sweep from there. Two seconds spent on setup is worth more than any single piece of food.
Ask where your tail will be, not where it is
This is the single habit that separates a 15-food player from a 40-food one, and it is worth knowing exactly how the rule works on our board rather than guessing.
When the snake moves without eating, the tail vacates its square on the same step the head enters a new one. The square directly behind the last segment is therefore legal — you can tuck in right behind your own tail and follow it around indefinitely. That is not a bug, it is the mechanic that makes tight play possible.
The exception is the one that kills people. On the step you eat, the body grows instead of shifting, so the tail does not move out of its square. If you dive into a tail gap at the exact moment you collect food, the gap you were counting on is still occupied and the run is over. Any time a piece of food is sitting near your own tail, treat the gap behind that tail as closed.
The practical version of this is one question, asked before every turn into a tight space: how many steps until I get there, and how many segments will have moved out of the way by then? At speed you will not do the arithmetic. You will develop a feel for it, and the feel is built by playing on Calm where you have time to check whether your guess was right.
When to abandon the comb
A pure sweep is safe and slow. If you comb the whole board and only pick up two pieces of food, you have walked a lot of empty squares for very little. So the routine needs a rule for breaking it, and ours is deliberately blunt.
Take the detour when all three of these are true: the food is roughly within the next two columns of your sweep, the direct route does not cross a lane you will need on the way back, and your length is short enough that the shortcut cannot seal you in. Under about fifteen segments that last condition is almost always satisfied. Over thirty it almost never is.
And one hard rule with no exceptions: never leave the pattern to chase food that has spawned behind you. Turning around means either crossing your own strips or looping the long way, and both cost more than one piece of food is worth. Let it sit. It will still be there on the next sweep, and by then you will be arriving at it from the right direction.
What the wrap switch actually costs you
The board ships with Wrap through walls switched on, so leaving the right edge puts you back on the left and the top and bottom connect the same way. Most players leave it on because it removes an entire category of death, and for a beginner that is the correct call.
It is also quietly incompatible with the comb. The pattern depends on columns having ends. When you can slide off the top and reappear at the bottom, "the top of the column" is no longer a place that exists, and worse, your tail can materialise on the far side of the board inside a lane you had mentally reserved. The deaths get harder to explain, which is another way of saying they get harder to learn from.
Our suggestion: learn on wrap, then turn it off once you can hold the sweep for a full pass. Solid walls kill you more in the first thirty seconds and much less after that, because a border you cannot cross is a border you can safely press your body against.
A practice ladder through the four speeds
The speed selector runs at eight, twelve, eighteen and twenty-six steps per second, labelled Calm, Normal, Fast and Silly. That is 125, 83, 56 and 38 milliseconds of real time per square. Each setting stores its own best score on your device, and switching speed starts a fresh run, so treat them as four separate games rather than a difficulty slider.
Work through them in this order. Do not skip a rung because the previous one felt easy once.
- Calm, wrap on, score ignored. One goal: complete two full comb sweeps of the board without breaking the pattern, even when food spawns somewhere annoying. This is the boring rung and it is the one that matters.
- Calm, wrap off. Same drill. You are learning where the columns end and how close you can turn to a border without clipping it.
- Normal, wrap off, detour rule active. Now start taking the shortcuts, and after each death say out loud which turn trapped you. It is almost never the last one.
- Fast. The gap between deciding and pressing stops being free. Use the three-turn buffer deliberately: queue the sideways step and the next descent as one motion instead of waiting to see the first turn land.
- Silly, for fun only. At 38 milliseconds a square nobody is planning. This rung is where you find out which parts of the routine have become automatic, because those are the only parts that survive.
Numbers we collected while running this routine ourselves, so they are estimates, not records or targets you should measure yourself against: on Normal with the comb running, a run that reaches around 40 food usually takes us three to five minutes, and roughly one run in four ends before 15 because of a setup mistake in the first thirty seconds. On Calm the same routine is slower and steadier. On Silly our runs mostly end in the teens no matter how clean the pattern is.
Three mistakes worth naming
- Turning early because you are nervous. A turn taken two squares before you needed it puts a corner in the middle of a lane, and that corner is still there ninety steps later. Commit to the full length of the column.
- Watching the food instead of the head. Your eyes should live on the head and the two or three squares in front of it. Food position is something you check between decisions, not something you stare at.
- Blaming the spawn. Food is drawn uniformly from the squares that are currently free, so it genuinely can appear somewhere inconvenient. That is exactly why the routine is built to not care where it lands.
Questions players ask
Can I follow directly behind my own tail?
Yes — the tail leaves its square on the same step your head moves, so the square behind the last segment is legal. The exception is the step you eat on: the body grows instead of shifting, the tail stays put, and the gap you were aiming for is still solid.
How many turns does the game remember if I press quickly?
Three. Each press is checked against the last turn you asked for rather than the direction you are currently travelling, so a quick right-then-up registers both. A fourth press in the same burst is dropped, and reversals are always ignored.
Why does changing speed restart the run?
Each speed keeps a separate best score. Allowing a mid-run switch would let a score built mostly on Calm land in the Silly column, so the run resets and all four numbers stay meaningful.
Is the comb always the fastest way to score?
No, and treating it as gospel will cap you. It is a default to fall back to, not a rule. Short snake and close food, take the shortcut. Long snake, finish the sweep.
The short version
Give the snake a route. Sweep columns instead of running errands, keep the body in parallel lines, predict the tail rather than reacting to it, and only leave the pattern when the food is close, the route is clean and you are still short. Then practise the boring rungs on Calm until the pattern holds itself together without your attention. The high scores arrive as a side effect.
