We played british Bulldog, Kerby, What Time Is It Mt Wolf, and many more...
We'd spend hours down the river at the Seven Acres and run across the 'pipe bridge'...no fear of sewage or falling off the bridge.
My younger sister and I used to drop sheets down from the top bunk and make a den on the bottom one.
Another favourite was zipping sleeping bags up, then standing up and putting them over our heads so only our feet were showing...we called that game 'bump in the dark' then slide down the stairs in them, it would always end in tears
My Parents couldn't afford much when we were young so we had to utilise what we could and use our imaginations...what fun we had, the simple things. None of this one player video game stuff, we played together and shared.
I remember getting our first computer. It was an Acorn Electron and to load the classic Spade Invaders game took about half an hour in the tape deck....
