The gamblers should use all the multiple to make the money,but most of the gamblers use to take risk with high capital on the betting which give 12x of their betting money.So the risking big capital in one game will leads to the loss of the entire capital in the casino games.
Yes, I think a gambler should try all the multiplier options to see where his/her luck favors him or her. It's kind of crazy to play with low odds of winning because that way your chance of losing gets higher and with a few lost bets you're out of your funds.
A smart gambler knows that when to place bets and how to place those bets. They don't really want to earn 10x within a sitting, even if a gambler with $100 portfolio gets a single win of 2x that's more than enough for him. Such gambler often place smaller bets but in very few scenarios they place big bets.
However, like OP said risking the full capital of your account in one bet is not worth it because a single loss will empty the account and you won't be able to place any more bets. It's better to place 100 small bets than a single huge bet because out of 100 small bets you have chance to win 40-60 of those but with 1 huge bet you lose everything. Huge bet means a bet with big multiplier.
