I just got this boredom buster games at a magazine. So this are not my ideas. I got this from total girl Phillipines magazine. Enjoy!

Game #1
Fortunately, unfortunately
Needs: 2 players or more
Start a sentence with 'unfortunately' and add something not so great, like, 'unfortunately we've fallen into a giant shark tank'. Then, the next person says something starting with 'fortunately' to change the stick to a good one, like, 'Fortunately, Sharks like us'. Continue flipping the situation from bad to good until you can't talk because you're all giggling to much or run out of ideas.

Game #2
20 questions
Needs: 2 players or more
This game is super easy. Basically, a person thinks of something, such as a famous character, an animal, or an object. The other players are allowed to ask 20 questions each. (Answerable by yes or no) to try to work out what the person is thinking of. A player wins if he manage to guess the correct answer by the 20th question he asks.

Game #3
Last letter, first letter
Needs: 2 players or more
Choose a category (for example cartoon characters) Then, have the first player say a cartoon character, like 'Rainbow dash'. The next player has five seconds to give a different animal, but it should begin with the last letter of the previous answer. In this case, 'hawk moth' or 'Hans' would work since 'H' is the last letter or 'rainbow dash'. This game continues until someone can't think of an animal within five seconds!
