How to Play Snake Past Length 100: Routes, Not Reflexes
Long Snake runs almost never end at a wall. Walls kill beginners. The run that hurts — the one that was going somewhere — dies around length 50, in open space, when the head slides into a pocket its own body sealed off three moves earlier. The cause is nearly always the same: taking the shortest path to the next piece of food, every single time, because that's what the game seems to be about. It isn't. Past length 30 or so, Snake quietly stops being a chasing game and becomes a routing game, and players who don't notice the switch are the ones who never see 100.
Greedy pathing is a loan
Beelining works brilliantly at first, which is exactly what makes it dangerous. A ten-segment snake can dart anywhere. The board is mostly empty, every route is safe, and the habit gets rewarded a few dozen times in a row.
But every bite adds a segment, and every segment has to go somewhere. By length 60 on a typical grid you aren't a dot chasing a dot any more — you're a moving wall that covers a third of the board. The shortest path treats that wall as if it didn't exist. So you curl toward the food, your body swings around behind you, and the region you're entering quietly loses its second exit. Nothing looks wrong until nothing can be done about it. On Inkplay there's a second tax stacked on top: every bite also speeds the snake up a notch, so the positions that need the most careful reading arrive at the highest speed of the entire run.
The fix is a different question. Stop asking how the head gets to the food and start asking where the head goes after the food is gone. If you don't have an answer, that food is bait, and the correct move is to not take it yet.
The lawnmower route
The old answer is the boustrophedon — a Greek word meaning roughly "as the ox turns," the path a plough takes across a field. In Snake terms: sweep the board in stripes. Down one column, up the next, down the next, keeping a return lane free along one edge to carry you back to the start of the pattern. Mow the lawn. Forever.
It feels ridiculous the first time, because you'll cruise straight past food and leave it sitting there. Let it sit. A route that covers every cell always reaches the food eventually, and — this is the actual prize — it can't collide with anything, because the head only ever enters lanes the tail has already left. Taken to the limit this becomes a Hamiltonian cycle, a closed loop that visits every square exactly once. A snake riding that loop cannot die. At all. It just grows until it fills the board, which is why every perfect-game clip you've seen is thrilling for one minute and then looks like watching a printer.
The cost is time. The reward is that the route removes decisions at exactly the moment you're least equipped to make them. At full speed, "keep mowing" is an instruction you can follow with your spine; improvised judgment four turns a second is not.
Your tail is a door that keeps opening
Mid-run, there is one guarantee on the board: the cell your tail occupies is about to be vacated. Head advances, tail retreats, always in step. Which means a head that follows its own tail is walking a corridor that renews itself — you can trail your own tail forever and never be trapped.
That makes the tail your compass. When you genuinely can't read a position, turning toward your tail is nearly always safe, while turning toward whichever region merely looks biggest is how pockets eat people. Open space can be a dead end. The square behind your tail never is.
One caveat, and it's the fine print that kills: eating pauses the tail for one tick — that pause is literally how the snake grows. Follow your tail at zero distance, grab food on the way, and the door you were counting on stays shut for a beat while your head keeps coming. Keep a cell of slack whenever food sits in the corridor between you and your tail.
When to cut the corner
Strict lawnmowing is slow, and a full sweep between bites gets tedious, so real scores come from the route plus disciplined shortcuts. The discipline:
- Cut only when you can trace the path back to your tail before you turn. Not "there's probably room." Trace it.
- Never enter a pocket smaller than you are. Thirty free cells and sixty segments of snake means the exit has to reopen before you run out of floor, and at speed you will not compute that in time.
- Food against a wall costs an extra turn to take safely; food in a corner costs two. Collect those on the sweep, not with a lunge.
- Scale the greed to your length. Under 30, cut everything and enjoy yourself. Past half the board, stop improvising entirely and ride the route home.
The trade underneath all of this — points now versus structure that keeps you alive later — runs through the whole genre. It's why you keep the stack flat in Blocks instead of chasing every tempting overhang, and why 2048 players weld their biggest tile into a corner and refuse to move it. Route players look slow for two minutes and alive after ten. That's the whole trick.
