After an argument about how to divide patients randomly into groups for a clinical trial some wanted to use a coin toss, others argued that coin tosses could be manipulated , they tested their theories on a group of medical residents. When given some basic pointers and five minutes of practice, the subjects could intentionally show heads as much as 68 percent of the time.

Then, move your thumb with light force to flip the coin into the air. You may have to practice with varying forces until you get the hang of this. For best results, flip with your dominant hand. Catch the coin in your hand so you can feel the surface of the coin. You can catch the coin in the same hand you flipped it with, or you can catch the coin in between both of your palms.

After you catch the coin, slide your thumb under your fingers to feel coin. This way, you can determine which side is flipped upwards and make adjustments so your side is on top. Practice flipping and feeling your coin so you can do it effortlessly. Continue trying the flick and feel technique until you are comfortable doing this without hesitation.

If your opponent catches you feeling the coin, they may call you out for cheating, and you will not win the coin toss. Have your opponent call their side of the coin, flip it into the air, and catch it in your hands. As you do this, feel the coin, and reveal your side of the coin to your opponent.

Then, declare yourself the winner! For instance, challenge your friends or family members. Method 2. Hold the coin near the end of your index and middle fingers. Position the coin so it is in between your index and middle finger. Ensure the side of the coin that you want to win is facing upwards as you do this. Flick your wrist upward and lift your index finger. To toss the coin, gently move your wrist up and release the coin.

As you do this, move your index finger out of the way so the coin gets tossed without much movement. Catch the coin in the same direction you threw it in. In one consecutive motion, open your palm so you can easily catch the coin after you toss it. Throwing the coin with this technique ensures the coin lands in the same direction as it started.

Meaning, if you started with heads, the coin will land on heads.
