Even if you say that Gates of Olympus is easier to wins the money, that still needs luck to wins, especially we are playing slot game that depends on our luck. You can wins much money from slot with $0.10-$0.30 per spin and gets Scatter or Free Bonus Rounds and hit the jackpot. But that will not happens too many times as slot game needs luck to win. I don't wants to lose entire deposit because I am trying to limits my gambling activity so I can prevents the big lose.
Bonus Buy can be a help for some people so they still buy that and hopes they can hit the jackpot. But they must realizes that Bonus Buy can't always gives them big wins so they must be careful spends their money to Bonus Buy. I prefer to playing as normally and not use Bonus Buy because that can makes me lose much money. I can forget to control myself if I often use Bonus Buy.
Exactly, the slot games are required a luck for a win but there is a possibility for playing a game a bit and check if this game is paying good or not. Also, hitting a jackpot is requiring a huge luck because the possibility of hitting a jackpot is extremely low for all slot games and it’s not related with the amount wagered. For example, people who wagered 0.10$ per spin can also hit a jackpot while people who wagered 1$ per spin too.
For not using the entire deposit, of course, you need to control yourself. For example, if I’m going to spend 50$’s on slots, in general I deposit 10-20$’s first and trying to have fun with it. This can also help me a lot about not losing the whole budget in one deposit and I’m able to play in different times in a day or different days in a week. Also, this is blocking the big lose for a limited time.
About bonus buy, yes, some gamblers are choosing it because of multipliers for the winnings and sometimes this bonus buy can pay more than expected. Also, it may cause a huge loss as well because in most of the slot games, the bonus buy price is 100x expensive than one turn price. I’m also preferring to wager normal than buying bonus from a game because it’s not guarantee but with 100 spins of course the bonus will hit at least once in general (Talking this about myself, not guarantee luck for everyone).
