Is there a ski jump game for PC?
Ski Jump in Games by Zaweba: spring off the lip, ride the gusts and land a clean telemark on a K90 hill, scored on distance and style. Free, offline.

There is: Ski Jump, on the Skill & sport shelf of Games by Zaweba, has you spring off the lip, ride the gusts and set a clean telemark landing on a K90 hill. Each go is three jumps, scored on distance points plus style marks from five judges. The app is free and works offline.
It's a game of three moments: the take-off, the flight and the landing. Get all three right and the distance and the marks follow.
The take-off
Click to push off down the in-run, then click again right at the lip to spring. Timing that second click is the first skill. Too early or too late and you lose distance before you are even in the air. Watch the lip, not the score, and click as you reach it.
If you prefer the keyboard, Space does the clicks and the Up and Down keys handle balance in the air.
Balancing in the air
Once you're flying, gusts tip you about. Move the mouse up to lean back and down to lean forward, keeping the marker in the green. Small movements are better than big ones. If you chase every gust with a large correction, you swing past the green on the other side. Make a small correction, wait to see its effect, and correct again.
A steady flight carries further. The longer the marker stays in the green, the better your jump tends to be.
The telemark and the judges
Click just before touching down to land in a telemark, the classic ski jump landing with one leg forward. A clean telemark is where style marks are won. Five judges mark each jump, and the highest and lowest marks are dropped, so one generous or harsh judge doesn't decide the score.
Distance points come from the K-point. Reaching it is worth 60 points, and every metre beyond it adds two more. So distance and style both matter: a long jump with a scrappy landing can lose to a slightly shorter one with a clean telemark.
Three jumps make a go, and your best score is kept on the game's tile along with how often you have played, in a scores file on your PC.
Practice pays off quickly in Ski Jump because the hill is always the same K90 hill. Once you know the in-run, the timing of the click at the lip becomes a matter of rhythm rather than reaction. Many players find their first jump of a go is the shakiest and their third the best, so treat the first as a warm-up and don't take risks with the balance until you have one good jump on the board. A clean, average-length jump scores better than a long one that ends in a scrappy landing.
Opening Ski Jump
Ski Jump sits with 16 other games on the Skill & sport shelf of Games by Zaweba. Press Ctrl+F and type ski to find it. The title card explains the rules and controls before your first jump, F1 brings them back, Esc pauses between jumps and F11 fills the screen, which shows more of the hill and makes the landing easier to time.
No adverts, no accounts, nothing online. The hill, the jumper and the wind are drawn in code, and so is every sound. If you like timing a single moment just right, Long Drive's three-click swing and Ten Pin's arrow are close cousins on the same shelf.
