For the fun of it, make any game created in history impossible to win. One person say a game and the next will try to make it impossible to win and state a new game.
Not clear? Look at the example below.
Me: Angry birds epic
Someone else: All enemies' stats at level 1, stage 1: 999999999999999999 for hp and attack. Usage of items are banned. Feed me.
Another person: Your venus flytrap is dead. <insert any games here>
I will start.
Angry birds go!
