Out of pure boredom, they come up with a game using the few things they have on hand in the cottage: a pair of dice, a cup, string and Props. When they suddenly realize it’s turned into a special game, they can’t stop. The first version of PlayProp is born. Later, the game accompanies Birger as he backpacks to Val d'Isere in France. Here, he lives and works as a ski instructor and travel agency owner for the next 7 years. He plays the game with skiers, tour guides and people from around the world who come to ski. The game is built upon with a colander, a bread basket and an old lampshade. The cup goes from player to player, with Props flying all over the place and lots of laughing and shouting. Every ski season, Birger pulls out the game - and every season, it improves.
