You will indeed get the same amount of tickets but you need to spend 5 times more money to achieve that. So it really is a great promotion especially if you like to bet on football games.
Talking about the effectiveness to gain more tickets, playing slot games is better than betting on football matches.
Simply because playing slot games can be done anytime without waiting unlike betting on football matches.
Obviously, it is all about preferences but I have to say that playing slot games is faster but riskier in order to earn raffle tickets.
That is true but at the same logic playing dice is better than any other game, because you could calculate the odds and the return, meaning you would be able to wager for something that has a very high chance of you winning, and then you could wager a small amount.
Obviously even in a bet with 90% chance to win, you will lose once out of each ten bets on average, and that means you could even lose 2-3 times in a row, so you can't expect pure profit from it, never expect profit from any type of gambling. But this would be the longest way to gamble, it would not make your money fully run out for a very long time and you would end up with a huge wagering amount eventually for sure.
