He has his luck playing on that slot machine and won so much money. I wonder how much he already spent before hitting the max-win because I do not think he only spent $5 in one spin and hit the jackpot.
It will not matter anymore even if he play thousands of dollars it will not matter because $2.4 million is $2.4 million, it took to years before the jackpot is hit again this only proves that you can be a millionaire playing a luck-based game but don't play thinking that you will be the next one, you will be the next one if you are lucky and luck is something is forced it will happen if you are in the right place at the right time.
