River Wild - Tutorial and Solo Play | Button Shy Solo Series

About River Wild, from BoardGameGeek:

Every year in the realm of Wild, the first snow of the season brings new life to the land and the creatures who inhabit it. High atop the tallest peaks, the sun beats down on this fresh blanket of white, creating a rushing river that floods the magical valleys below. In River Wild, you must carve out the most harmonious land possible, plotting the river's course to create protected valleys for local wildlife to thrive. A protected valley is defined as a valley completely surrounded by river or mountains with no card gaps. Each turn, select one of the three river cards on display and add it to your land to extend your river. All cards must be played below the source card so that your river extends "downstream" (toward you). When choosing a card, you may look at and play either side of a card. Refill the display, then choose again, continuing play until all cards have been added to your land or until you are unable to play any more cards. Unprotected valleys don't score, and protected valleys score based on the wildlife (dragons, jackalopes, toads, and unicorns) and scoring goals contained within it. Make matches to score as many points as possible.
