I've made one up that I do in lunch period with my friends. It's where you roll a dice and you have to hit the other person's hand at the number the dice rolls. It's funny as hell. Usually, when I play, the dude I'm playing with would call a junior and tell him to hit my hand. Haha, my hand was sore for like 2 days or something from playing that.
Not really but when I was a kid me my friends changed up the rules to various kid games like hide-and-seek, tag, redlight greenlight 123,hopscotch make it more interesting.
for card rides and stuff like that, i made up a game called the 'ipod game.' which is basically when someone goes through their ipod and describes artists, then the other people have to guess who it is.
examples:
-One of this group's album covers had a baby swimming underwater. Answer: Nirvana
-Queen of Pop - Madonna
i dont think we made this up...but if me and my girl friends got nothing to do, and we feel like singing we play the continue-the-song game...you'll sing a song that can continue from the last word of the last song...like this
It's just too little too late a little too wrong and i can't wait...
(then the next one must sing a song with a "wait" on it's word w/ time limit)
