From the publisher:
"Sniff has gotten into a trouble on the Lonely Mountains. He is stranded on a cliff after all the bridges have collapsed after him. Each player has to find 5 bridge steps among the tokens to build his or her own hanging bridge, and get over the gorge to help Sniff. A lot can happen on the way: one might get caught by the officious Constable, who wants to know who stepped on Hemulen's flowers, bridge steps might fall from a backpack, and the nimble Nibling eats them at once. Luckily Too-Ticky is enjoying the sunny day and if one is lucky he or she might get a lift from Too-Ticky on her hot air balloon. There are also some shortcuts along the way, but it takes a bit of luck to find them. The winner is the player who first completes his hanging bridge and gets to Sniff's rescue."
Seikkailu vuorilla ("Adventure in the Mountains") is a Moomin-themed roll-and-move game for 2-4 players.
