The only rule of combat
Every fight in Planet Snake comes down to a single mechanic: a snake dies when its head enters a cell that a body already occupies. That is the whole of it. Your head is the only part of you that can be killed, and another snake's body is the only thing that can kill it (your own tail is the other — more on that later).
This cuts both ways, and it produces the rule every fight obeys: you win by making the enemy's head run into your body — never by driving your head into theirs. If your head reaches their body first, you are the one who dies.
The cut-off: your bread-and-butter kill
The reliable way to score a kill is the cut-off: cross in front of a moving snake and turn so your body lands across the cells it is about to enter. With nowhere left to go, its head runs into your flank and it pops. You supplied the wall; it supplied the head.
To pull it off:
- Read their heading. A snake can only step to an adjacent tile, so its next move is one of the cells directly ahead of it. Aim to occupy those, not the cell it is sitting in now.
- Lead the target. Commit to the space in front of them — the way you would pass a ball to where a runner is going, not to where they are.
- Turn across, then seal. Once your body is over their lane, keep turning so the wall lengthens and curls, closing the exits before they can round either end.
- Use your length. The longer you are, the wider a net you can throw. This is the real combat payoff of growing big. (See the movement guide for how gentle and sharp turns differ — sharp turns are what snap a trap shut.)
A head-on is a trade, not a victory
Because two heads meeting kills both snakes, charging someone head-first is never an attack — it is a mutual trade. Occasionally a trade is worth it: you drag a dangerous leader down with you, or you were cornered and dead anyway. But go in knowing you are spending your own run to do it.
Most head-on deaths, though, are simply accidents — two players lunging at the same gap. To stop donating your run:
- Never contest a single cell. If your head and another are both arrowing at the same tile, peel off. The snake that flinches lives; the one that "wins" the cell dies too.
- Approach in arcs, not straight lines. The curved horizon hides oncoming snakes until they are close, so drifting sideways buys you the half-second needed to avoid a face-to-face.
- Remember you bank your size either way. Your score is your size the instant the run ends, so a trade still banks everything you had grown (the scoring guide explains why). Trading down a rival costs you nothing on the board — only the chance to grow that particular run further.
Invincibility turns you into a battering ram
One power-up rewrites the rule above: Invincibility. While it is active your head can enter an occupied cell and survive — which means for those few seconds you can drive straight through another snake and it dies, not you. It is the only time a head-first charge actually wins.
- Pick your target before it expires. Line up the densest cluster of enemies and plough through their bodies — every snake whose cell you cross is gone.
- Hunt the crowns. Invincibility is your best window to take down a bigger, more careful player who would never lose a fair cut-off.
- Do not waste it running. Burning Invincibility just to flee is a poor trade — escaping is what dash and teleport are for.
The flip side: assume every snake bearing down on you might be lit up. If one charges head-on and refuses to flinch, give it room — it may be invincible, and you are the one about to pop. The power-up guide covers durations and the rest of the kit.
Fight with the planet, not just your body
The arena is a sphere, and its geometry is a weapon in its own right:
- The wrap-around has no walls. There are no edges to pin an opponent against — but there are also none to back yourself into. Chasing a snake "off the edge" does nothing; the surface just curves back around behind you. Plan for the loop.
- The curve hides ambushes. Anything beyond a short distance drops below the horizon, so you can lurk just over the curve from a fruit cluster and cut off whoever comes to farm it.
- Pentagons are free escape hatches. Twelve pentagon tiles are scattered across the planet, and each is a free teleport portal. When a fight turns against you, routing through one repositions you for nothing — far better than spending size on a manual jump (more in the movement guide).
Choosing fights — and choosing to run
Here is the part most players get wrong: in Planet Snake, kills are worth nothing on the leaderboard. No score, no dropped food to scoop up, no bonus — a dead snake simply vanishes. Clearing a rival only removes a threat and frees the fruit they were contesting. So fights are a means, never the goal. You fight to survive and to claim territory, not for a body count.
That makes discipline your real edge:
- Only commit with an advantage — a better angle for a cut-off, an active Invincibility, or a clear escape lane. No advantage? Do not engage.
- Always keep an exit. Never coil so tightly that your own tail boxes you in. Self-collision kills you for free, and plenty of "great" attacks end with the attacker trapped inside their own loop.
- Know your escape tools. A dash is a burst of speed that steadily bleeds your weight as you hold it — ideal for breaking contact, wasteful if you cruise on it. A manual teleport is your panic button, at the price of ten percent of your size. Both are detailed in the movement guide.
- Let the small stuff go. A lost fight at small size barely dents anyone; a lost fight after a long growth streak throws away a huge bank. The bigger you are, the more selective you should be.
Beating bots vs. beating humans
Every world mixes real players with AI snakes, and the two lose in completely different ways.
Bots are cautious foragers. They steer toward the nearest fruit, veer away the moment another snake gets close, and will not knowingly turn into an occupied cell — but they react only to the danger right in front of them and never anticipate where your body will be next. So:
- They will never hunt you or rush a head-on, so do not wait for them to blunder — you have to close the trap.
- Because they flee anything nearby, they are easy to herd: press from one side and a bot turns predictably away, letting you steer it into a wall of your body or its own tail.
- Spring the cut-off fast. A bot will sidestep the single cell right in front of it, so you win by sealing its last open escape route in the same instant — before it can pick a new one.
Humans bluff, bait, and hold grudges. They will fake a retreat to draw your cut-off early, contest fruit aggressively, and gang up on a fat target. Against them, patience and unpredictability beat raw mechanics — vary your approach angles, do not telegraph the turn that seals a trap, and never assume a retreating player is actually finished.
Put it together and you have the whole fight: protect your head, weaponise your body, spend Invincibility wisely, and only swing when the kill is free. Sharpen everything else in the complete strategy guide, or drop into a world and start throwing walls.
