Different gambling activities have different chances attached to them and when I mean chances I am referring to the probability you have for actually win the bet or hit the jackpot in games like crash and slots. This is basically because sometimes unrealistic bets can sometimes play out as a win and some other times bets that have a high winning chance can eventually become the losing bet.
I believe people who gamble on sports may understand this better since sometimes in sports betting some gambler's prefer to go for the smaller odds that usually have a higher winning chance and sometimes they can still end up a losing game however some prefer to go for the big game with big odds and smaller winning chances.
What's usually your pick as a gambler since sometimes some persons are luckier than others?
It is impossible to calculate the odds in slots, because it is like a "black box" about which only RTP and the maximum multiplier are known. The odds can be known in advance in roulette, as the game is completely transparent to mathematics. Based on this, various strategies are used. For slots, the more spins there are, the greater the chance of getting a big multiplier that will outweigh the House Advantage. However, the stakes are small (because the bankroll is limited). You can make big bets in roulette, because there is no point in a large number of spins (this works for House Advantage). If we draw an analogy with betting, then I would rather prefer high odds. A small chance of winning can be increased by several bets of this kind. At least it's more interesting than betting on favorites all the time.
