What is Luck?
A concept which many players view as essential when playing in a land-based or online casino is that of luck. For many, an absense of luck means that they will be walking away not with the riches from the roulette table or slots that they hoped for, but instead will mean an expensive and unprofitable experience. So before sitting down to that game of blackjack, not to mention during it, players will wear their lucky underwear, comduct a superstitious ritual, offer up prayers... In fact, basically do anything which might bring them luck and good fortune in the casino and win them some money. Of course when gambling for high stakes players are likely to be even more anxious for Lady Luck to be smiling upon them due the the large sums of money at stake.
Probabilities and Skill in Casino Gambling
But what is luck? In reality, the outcome of the vast majority of casino games are based on probabilities rather than any element of player skill. Of course there are exceptions, with how a player plays their hand in blackjack or video poker for example having a significant effect on whether they win or lose. But for games with independent events such as roulette where future results are no indication of future outcomes, provided that there is no bias in the roulette wheel of course, it is all a matter of probability rather than luck or any other outside influence.
However many players, even professional gamblers and experienced casino veterans, cling to the theory of luck and the amazing powerful force of their lucky rabbit's foot or four leaf clover. Where the confusion often lies is that results often occur in streaks. Whilst for example the result of a roulette spin has the same 1 in 37 or 1 in 38 chance(depending upon whether playing European Roulette or American Roulette), that does not mean that a number will come up only once in 37 or 38 spins. Sometimes it will come up more than once, sometimes it will not come up at all. Those who bet on the right side of these streaks will win money and feel lucky, whereas those who bet on the wrong side and do not see their chosen numbers come up will curse their bad luck.
It is these streaks, sets of results and ability to sometimes come out ahead that make casinos and gambling so attractive and keep people coming back for more.
