That's a $20 bet, I cant say it is a low amount especially if we are talking about slot game which is a high volatility one. Nice win indeed although we do not know how much he spent before he hit that nice payout. Slot can be a life changing game if we are so lucky to hit big win but in can be something very worst when cant find any big win after thousands spins. Congrats to above player though, he should spend it wisely and should not be greedy to try to get more winnings.
