So many, we made up a lot of our games. One was called "Jimmy". I had two sisters. Here is how it was played: one sister would be "Jimmy", one would be the judge, and one would be the policeman. The one who was "Jimmy" is an escapee from jail. He would go somewhere in the house (or in the yard- wherever we were playing) and he would pretend to be a statue in some sort of pose. After counting to 100, the policeman would go find Jimmy and bring him to the judge who would proceed to chew Jimmy out and tell him to stop escaping from jail. Then, we would take turns being Jimmy, the policeman, or the judge. If my younger cousin was over, the game became "Jimmy and Jenny" and we had two escapees.
It was a hybrid between hide and seek- no one was hiding, and statues.
We also played a variation of freeze tag with either just the three of us, or for MORE fun my three cousins. My mother would turn on the radio, we would dance wildly and then she would stop the music, while we were frozen in whatever pose we happened to be striking when the music was turned off. This game was hilarious as we laughed at each others poses.
There were a lot more, though. I think the best were the weird games we made up ourselves.
