Climb The Mightiest Mountain!

About Unsurmountable, from BoardGameGeek:

You've climbed all of the mightiest mountains, yet there's one towering titan that's always eluded you: the mountain where anything can happen. In the whisper-thin air the paths twist and shift as you climb, stranding the unprepared and confounding the overconfident. Do you have what it takes to summit this perilous peak? In Unsurmountable, players will be tackling the rocky slopes of an ever-changing mountain. As the game unfolds, they must place the next piece of the path carefully in order to complete a route to the top while simultaneously meeting any additional goals for the round. It may sound like a walk in the park, but this puzzle has plenty of pitfalls to keep players on their toes. Unsurmountable is the next title in our Simply Solo line, following Food Chain Island and Ugly Gryphon Inn. These titles were designed by Scott Almes for single-player only, focusing on elegant rules that create complex situations. Like the previous two games, Unsurmountable delivers a fun puzzle that's sure to hit the table again and again.
