I was just playing Hi-Lo, making small dollar bets, if it's 5 number card I select higher card and win, if it's 10 number then I go with 'low' and win.
Then I was greeted with Ace card, minimal possibility for equal card right (i.e, Ace), so I go all in, and guess what happens, the result is Ace means I lost the bet.
Then I have all sorts of thoughts blaming casino, like do they manipulate the result of the game when user goes all in. I am sure they are all fair, it's just that the possibility of losing the game may be minimal but it's never 0.
Usually I'm more into the big bets, but the smaller bets are more likely to win. But it is definitely possible to win if you gamble according to the rules and skillfully. But I generally bet more on cricket, currently I like small numbers in IPL, and it's better to bet with guaranteed win with no benefit.
