It would be nice to know your ages, but if you are under age 16 or so, some of the best fun I can remember occured outdoors. Do you have bikes? Is there a park nearby where you can all play a game of catch? My friends and I used to play this game called manhunt, it is like hide and go seek but outdoors and with clues left by the escaped convict. Each clue leads to the next until the search party finds the escaped convict at that point it becomes a foot race. If the convict makes it to base, then they are free and they choose who becomes the next convict. If the search party catches the convict then then he/she has to make more clues and hide again.
