Snow Rider

Snow Rider puts Santa on a wooden sled at the top of a mountain at night and lets go. The slope never ends: trees, dead trunks, rocks, snowmen and rolling snowballs come at you faster and faster, ramps throw you into the air, and gifts wait in the lanes between. Hold left or right to carve across the snow, and jump to clear the low obstacles: stumps, logs, fences and campfires. Hit anything taller and the run is over.

Every 20 metres is a point and every run ends on a card with your score, your best and the gifts you collected. The gifts are the currency: the sled shop has twenty sleds on a turning ring, from the Red Racer, the Ice Glider and the Candy Cane to a cardboard box, a snow saucer, a bathtub, a Viking ship, a pizza, a shopping cart, a hover board and Santa's own sleigh. Your gifts, your sleds and your best score are kept on the device.

It runs on desktop with the arrow keys or A and D and Space to jump, and on a phone by holding the left or right half of the screen with a JUMP button. Runs are quick, a minute or two, which makes it easy to try for one more.
