I used to have one but not anymore.  Since I learned that luck-based gambling games result is dependent on RNG, I feel shame having that kind of superstition.  But I know someone who blows his closed hands before spinning a slot (physical casino slots) or tossing coins (cara y cruz or coin flip), believing that it will bring him luck.



As I stated, I used to believe in superstition, and I used the rubbing both hands against each other luck invoking technique (LoL), but now I know it was all in vain  .
