Princess Ladder is a cooperative and communication limited cardgame, for 3-6 players.
Based on a princess-abducted-by-dragon story, the game drives the players to the highest window of dungeons, where 4 sisters princesses are to be saved, by using numerical ladder cards. The active player knows (most of time) the exact height and asks others for the good card to add to his own ladder. Alas, he can only speak with 2 words : “More” or “Less”. More, the princess as well as the current page of the story book tell the players how to save her.
When each player ended the round, ladders are added and the total is compared to the dungeon height. If equal, princess is saved, otherwise, dragon takes the princess away and players turn another page of the story book. At the end of the book, if all princesses are not saved, the game is over and lost.
There’s some variant rules in the booklet to increase game length and/or difficulty.
