Think is a Trivia game with 5 knowledge areas.
On each player's turn, another player takes a new Card for reading the question(s).
On each Card there are 5 questions, for one each knowledge area. Which question is asked is determined by rolling 2 dice.
Rolling doubles or 6s results in a special effect, such as getting a free Point or getting 2 questions.
Different numbers (without 6) gives the active player the possibility to choose the knowledge area.
1 question/area on each card is bold. This is the master question where you bet 2 or 3 of your previous owned victory points, for doubling or loosing them.
In the small editions the actual Player gets the card for knowing the answer, in the big boxes there are additional "nuggets" (black stones) for counting the victory Points.
Game Ends when 1 player has a predetermined amount of victory Points.
