The Rival is a way to play Skis Wild alone with the full 114-card deck. You play by the regular rules against a rival skier run by the deck. The first to fill every limit wins: Ski School 4, Green Runs 3, Blue Runs 2, Black Run 1 and Double Black 1, in that order.
On your turn, draw one card from the draw pile or take the top of the discard pile, then play one card or discard one. To ski you need Lift Open, Lift Ticket and the right Gear face up, and no Trouble on you. Your Trouble cards go on the Rival, and your Yeti can take one of its runs.
The Rival has no hand. On its turn it turns over the top card of the draw pile. It skis any run it still has room for, in any order. A green card clears its Trouble, a red card lands on you, a blue card protects it, and the Yeti takes your highest run. Everything it cannot use goes on the discard pile, where you can take it.
There are three levels. At Greenhorn the Rival needs the matching remedy to clear a Trouble. At Hunter any green card clears it. At Legend the Rival also starts with one each of Ski School, Green Runs, Blue Runs and Black Run.
