'Think' is Turkey's most-watched daily quiz programme. With more than 3500 episodes since 2009, everyone from all over Turkey turn on their TV's to watch 'Think' live at 7:45PM every weekday.

In 'Think', 4 competitors play the quiz one at a time. As questions, each player tries to find words as answers from brief descriptions, starting with a 4-letter word. With each question, the letter count of the words rises, until a 10-letter word where the player's run ends. If players can find the correct word on a question, they win points equal to 100 times the letter count.  If they have difficulty finding a word, they can 'purchase' a letter for 100 points. Players have limited time for their whole run to find as many words as possible and collect points. The player who has the most points wins the day and goes to the week finale. The last day of each week is played as the week finale where winners from each day compete to become the week's champion.
