1. One is wearing a blindfold, while the other guides.
It's pretty simple. You just need to grab hold a finger of your blindfolded partner and let them touch parts of your body like the inside of your arm, cheeks, forehead, or stomach.
2. Your partner has to guess.
Once you make them touch the specific part of your body, they simply need to guess where you've made them touch. If they guess right, they get a point.
