ZigZag Snow Mountain

The description that travels with this game in the GameMonetize feed belongs to a different game. It promises a freeski simulator with named grabs, a halfpipe, backcountry runs and a licensed Swiss resort — that text is the store listing for Just Freeskiing, by the German studio randerline. Open the game and you get one button.

What you actually get is better than the mix-up suggests. A skier stands under an inflatable start gate at the top of a narrow snow corridor. Click once and he sets off on a diagonal. Click again and he flips to the opposite diagonal. That is the whole control scheme: one press, one turn, and no way to stop, slow down or go straight. The corridor bends away below you in a zigzag, and your job is to keep flipping in time to stay inside it while sweeping up the yellow stars along the way.

There is no health bar and no second chance. Every fence post, tree, stump, tyre pile, snowman, yeti and both edges of the piste carry the same lethal tag — 274 colliders in total in the build — and touching any one of them puts a puff of snow where the skier was and ends the run. A good run lasts a minute. A bad one lasts four seconds.

The game is not called ZigZag Snow Mountain either. The build inside the iframe announces itself as ZigZag Snow Ski, and it is a Unity rebuild of Groovy Ski, made by BlackMoon Design — a studio in Poznań, Poland — and published by Famobi of Cologne. The evidence is still sitting in the file names: the side artwork is called TloNaBokiDlaFamobi, Polish for "background for the sides, for Famobi", the obstacles are balwan (snowman), beczka (barrel), opony (tyres) and pieniek (stump), and the soundtrack file is named "groovy ski". Famobi's copy went live in December 2015; this Unity rebuild was uploaded in January 2022. Groovy Ski holds a 4.4 out of 5 from 1,627 votes on Gamezop.

One honest warning before you start: the rebuild is a trimmed version. The original had five levels, a saved high score and a shop where stars bought hats and goggles. This build keeps the ten slope segments and the stars, but the three reward slots the code still expects are empty, the Head and Face buttons start switched off, and nothing is saved between runs.

Why every skier zigzags, and the sport built on it

This is the part the game gets right without ever explaining it. Skiers do not zigzag for style. They zigzag because turning is the only brake they have.

Every slope has a fall line: the most directly downhill line on it, the path a loose ball would take. Point your skis down the fall line and gravity does all the work, which is why a straight run gets fast very quickly and stays fast. The way a skier controls that is to travel across the fall line instead of down it, linking turns to either side, converting downhill speed into sideways travel. Steeper pitch, tighter turns. That rhythm — press, cross, press, cross — is precisely what this game asks of you, minus the edges and the knees.

Racing turned the rhythm into a discipline. Slalom is the tightest of the alpine events: an FIS men's course drops 180 to 220 metres of vertical and asks for 55 to 75 gates, with women's courses slightly shorter and 40 to 60 gates. The name is Norwegian, from the Morgedal and Seljord dialect — sla, a gently inclining hillside, and låm, the track skis leave behind. Arnold Lunn wrote the modern rules in 1922 for the British national championships, pairing the flags into gates and scoring on time alone, and slalom entered the Winter Olympics in 1936.

Look at the fenced segments in this game with that in mind and they stop looking like decoration. The wooden panels are gates without the flags: they force a fixed turn cadence, they punish a late edge, and they make the run about rhythm rather than reaction.

Ten segments, 67 stars and four yetis

The build is small and it is worth knowing exactly how small, because that is what makes it readable.

There are ten slope segments, hand-placed rather than generated, and a run is stitched together from them in no fixed order — my first attempt opened on the yeti segment, the next three on fenced ones. Nine of the ten carry stars; the tenth carries none:

• Six fenced segments. Wooden panels on both sides, 5 to 9 trees inside, plus one to three double trees. Two of them add five snowmen each and carry the biggest star haul in the game, eleven apiece.
• Two tyre chutes. The walls become stacked tyres and the obstacles become stumps — three in one, two plus a lone barrel in the other.
• One log chute. Walls of felled timber, four trees in the middle, six stars.
• The yeti segment. No walls, no stars, four yetis with their own run animation and drop shadows.

Add it up and the run is worth 67 stars at most. There are exactly ten checkpoints, one per segment, and 274 lethal colliders between you and the last of them.

The yetis are a joke with a long history. SkiFree, written by Chris Pirih and shipped in Microsoft Entertainment Pack 3 for Windows 3.0 in October 1991, let you ski a course that ended at 2,000 metres — at which point an abominable snowman appeared, chased you down and ate you. It became the most remembered thing about the game by a distance, and it is why a yeti is now standard furniture in browser ski games. Here they do not chase. They just stand there, in the one stretch of slope with nothing to steer by.

One tap, one turn, and no second chances

Strip a game down to a single button and two things follow. Nobody needs to be taught anything — there is no tutorial screen here, only a small hand icon, because a press is the entire vocabulary. And failure has to be instant, because a one-button game has no room for damage, recovery or a health bar. You are alive or you are a puff of snow.

That trade is why one-tap games took over phone screens. A run costs seconds, a mistake costs one click on Play Again, and the loop restarts before you have thought about stopping. The cost is depth: without the shop and the saved high score of the original, there is nothing to grind towards. This is a game you come back to, not one you progress through.

Playing ZigZag Snow Mountain unblocked at school

It is one HTML5 page with a Unity WebGL build inside it. Nothing installs, there is no plugin, no extension and no account, so it behaves the same on a managed school Chromebook as on a gaming PC, provided this site is reachable at all. Press play above and it starts inside the page.

The one-button control helps here too: a trackpad is a perfectly good input device for this game, which is more than can be said for most browser ski games. Expect a short GameMonetize video advert before some runs — it appeared on the first launch and not on the three after it.

More one-input runs

If what you liked was the single-input rhythm rather than the snow, the catalogue has more of it. Skate Hooligans is the same instinct on four wheels, Dune Surfer 3d swaps the piste for a sand slope, and Relic Runway has the same appetite for ending your run without warning. For the version where one input matters and everything else is automatic, Superbike Hero pins the throttle open and leaves you nothing but the steering. Or browse the rest of the casual category.

1. Read the slope first. Nothing moves until your first click, so take a moment to see which way the corridor bends below the gate. That free look is the most useful second in the game.
2. Click to launch. The skier leaves the gate on a diagonal and immediately starts covering ground sideways as well as downwards.
3. Click again to flip. Each press swaps left-lean for right-lean. Holding the button adds nothing — the turn fires on the press and the new direction sticks until you press again.
4. Take the stars that are on your line. They are worth the same wherever they sit, and the counter in the top-left corner is your only score. Chasing one that is off your rhythm is how most runs end.
5. Do not touch anything. There is no glancing blow. Fence, tree, yeti or edge of the piste, the result is identical.

Things worth knowing before your first run:

• The edges are as deadly as the trees. Bound left and Bound right are tagged exactly like a tree trunk. Plenty of first runs end with nothing on screen but empty snow.
• The turn is instant but your position is not. By the time you notice you are late, you have already travelled. Press about half a skier-width before the corner, not on it.
• Trees come in singles and doubles. The double trees sit inside the corridor and block roughly twice the width. On the fenced segments they are the thing that actually kills you.
• The yeti segment has no fences. It is the only one that opens out, which makes it feel safer and is not. Four yetis stand in open snow with nothing to line yourself up against.
• Two segments swap the fences for tyres and one for logs. They read as scenery at first glance. They are not; they are the wall.
