Ski Free

Ski Free is a JavaScript port of Chris Pirih's 1984 Apple II classic, by Daniel Hough. You ski down an endless procedurally generated slope, jumping rocks and trees, building speed — and if you make it far enough down the mountain, a yeti appears and starts chasing you.

It is a faithful reimplementation in modern JavaScript: same slope, same sprites, same jingle, same one-hit fatal jump. The original was Apple II shareware from 1984 and is now in the public domain.

How to Play

1. The slope descends automatically. You only control direction and jumps.
2. Press space (or tap) to jump.
3. Hold down to tuck — you go faster, but you cannot steer while tucked.
4. Rocks and trees are obstacles. Hit one at speed and you crash.
5. The further you get, the faster it goes. The yeti shows up after a set distance and will not stop.

Controls

• ← → or A / D — steer left and right
• ↓ or S — tuck for speed
• Space — jump
• Touch — tap to jump, drag left/right side to steer

Tips

• Tuck on the straights, stand up before the trees. Speed is only useful if you are still pointed at empty snow.
• The slope scrolls faster the further you descend, so late in a run your reaction window is genuinely short. Short hops beat long ones.
• The yeti does not despawn. Once it is out, the only question is how far you get before you clip something.

Save Data

Nothing is saved. The run ends when you crash and you start again.
