Insert the poker chip between your thumb and pointer finger. Align the front edge of the poker chip with the second knuckle of the pointer finger. Adjust the poker chip according to the size of your hand.
Push the poker chip with your thumb. Lower your pointer finger and allow the poker chip to flip over the top it. It will lie flat against your finger.
Lift up your middle finger so that the poker chip catches at the bottom of it. It will slide down between the crevices of your fingers and support itself against the middle finger.
Align your fingers so that they are close together and even. The chip will become upright again. Repeat Steps 1 through 3 for the remaining fingers.
Catch the poker chip in your pinky finger. Reverse the process or lower the poker chip to your thumb. Sink the poker chip between your ring and pinky fingers while you bring your thumb across to retrieve it.
Practice the poker chip knuckle roll regularly to master the trick.
