Why?! is a set of orignal mysterious riddles, known also as black stories. The rules are simple. One of the players becomes a Game Master - he reads aloud riddle introduction and then silently reads the answer. The rest of the players ask yes or no questions to the Game Master. The game ends when the players guess the mysterious course of events.

Warning! The mysteries are divided into four difficulty levels. The easiest ones can be solved in a matter of minutes, while the hardest can give hours of fun to a large group of players.

Why?! introduces new mechanic - Key Points. Players don't need to guess every single detail of the answer. Game Master is given a set of Key Points for every mystery, which summarize the whole course of events. When players know all of them the game ends, and Game Master can read the answer aloud.

The players can also compete! The one who guesses most Key Points wins!
