It is a fun way to play with more people and requires either no skill or lots of skill if that makes sense
Step 1: How To Play
One person spins the coin on a table or any flat surface. Then the other person has to touch it and keep the coin spinning. You can flick it, swipe it or touch it lightly, whatever it takes
This process goes back and forth until someone touches it and the coin stops spinning and falls over.
When this happened the person who made it fall has to line up their knuckles and the other person takes the coin and swipes and releases the coin so it hits the persons knuckles.
First one to bleed, wins
Step 2: Rules
Even the slightest bit of blood on your fingers means you lose
And if more people join the newcomer touches it first, I recommend from 2 to 6 players
