Cops and robbers was always fun. We would play it and run after eachother, but sometimes we would use our bikes and have high speed chases. When my cousins would come over, we would play "sharks and dolphins" with grandpa- same rules as cops and robbers.
Over time, cops and robbers evolved into "jailbreak" when we were teenagers. We would wait until dark and the cop would have to close their eyes and everyone would hide. Then the cop would use a flashlight and hunt us down. In order to be caught, they would have to shine the light on us and yell out our correct name. We would have a "jail", usually a table where we would go when/if we were caught. Other jailbirds could come and release you if they went to the jail, touched the table and loudly yelled, "Jailbreak!"
