You could play some simple games like 'I Spy' or tell stories. For example, each person can share an interesting experience from their life.
One way to pass the time is to have a singing competition. Singing your favorite songs can be really fun. Another option is to do some simple exercises, like stretching, to keep yourselves occupied. Also, discussing books or movies you like can make the time go by faster.
Well, first of all, you can start by sharing your dreams and aspirations. It's a great way to get to know each other on a deeper level. Then, you could play some word games like 20 Questions. You think of an object and the others have to ask up to 20 yes - or - no questions to figure out what it is. If you're feeling creative, you can also try to come up with a group story. One person starts with a sentence, and then each person adds a sentence in turn to build the story. This can be really engaging and make the time fly by.
