About Slots Welcome Bonuses
The welcome bonus is an important stage of membership of your online slots site. It’s the first impression players have of the brand, as well as the first hurdle they take when they try to withdraw any future wins.
We’re talking about the first deposit bonus, the multiple deposit bonus and any other bonus related to joining an online casino.
So how do bonuses for a slots deposit work?
They work by providing a reward in exchange for signing up for an account, usually adding bonus funds on their first deposit to the player’s account. The first 100% match deposit bonus is the industry standard and most popular. If you deposit $ 20, you get $ 40, with the wagering requirements subject to $ 20.
Deposit bonuses come in many ways, but some are the same despite what the headline offer is, this is because of the terms and conditions that come along with the welcome offer. So whichever offer attracts you $ 500 free, 200 free spins, 5 deposit bonuses, 300 percent match, $ 10 deposit get $ 60, etc. They all carry requirements for wagering.
What are wagering requirements and why do they have deposit bonuses?
Here’s why online casinos don’t offer free stuff, the bonuses they offer aren’t really free. Since incentives are subject to conditions for wagering. The buried withdrawal hurdle is usually buried under the terms and conditions.
The terms are conditions that are boring for any online slots site, cleverly small, tactically spaced, and hard to read. Strange when you’re talking about it, because the terms and conditions contain the most important thing about the slots site. Whoever actually reads the terms and conditions? Anyone who wants to know if they might ever get their slots winnings?
So how do the wagering requirements for deposit bonuses work?
Example: if you deposit $ 40 and play with $ 80 (using a regular 100% deposit bonus), $ 40 of that $ 80 (bonus) will have to be wagered several times. Wagering rates range between 5x your bonus and 50x your bonus, maybe more. But in our case, we will use 35x wagering.
Are you still with me? So if you deposit $ 40 and get $ 40 free, you’re going to have to wager that bonus 35 x before you can withdraw any winnings related to that bonus. You’d have to wager through slots and casino games worth $ 1400. But wait, as far as wagering is concerned, not all casino games are equal.
Not all slots and casino game wagering are equal
In our casino deposit bonus example above, you’ll have to wager $ 1400 (your $ 40 bonus at 35x wagering) before you can win so to speak to your wallet! That means withdrawing your bank account winnings. So how are you wagering through that $ 1400 and what games are doing it faster? Note that not all games contribute equally to your wager. Some are actually worse than others.
I wading waste deep into the terms and conditions to get the information for you. It’s painfully boring, my eyes squint, and trying to understand it hurts, but I have to read on. It is here that we find out which slots or casino games best contribute to wagering bonus amounts.
Slot games contributed 100% of the wagering amount on the US slots we looked at, while classic slots contributed 75%. Live dealer games like Roulette and Blackjack, on the other hand, gave only 5 percent to wager the reward.
Top tip, play slots online while you still have money from the deposit bonus. You’re going to work even easier through this wager. But check the online casino terms and conditions that you plan to deposit with first.
How casino rewards first deposit function?
Look logically at this, we said in our example that if you deposit $ 40, you’re playing with $ 40. But you have to play through $ 40 35 times to withdraw winnings, that’s $ 1400. It’s not, nor is it intended to be, an easy or quick process to do. That’s why casino bonuses first deposit work, keeping us playing.
We’re getting excited, playing longer, entering games and finding slots we like playing. We see jackpots and leaderboards for losers; winners, and for ourselves, we see future wins. All while seeking to wager from that $ 40 deposit bonus cash by $ 1400.
Why do deposit bonuses work?
It’s not in our interest entirely, but here’s the good news. Once we have met the bonus wagering amounts, we can get on with business. When we win, we actually win.
US slot bonuses and casino deposit bonuses may offer the earth the best way to approach casino and slot bonuses, but players should look closer. See any bonus as a free look at the slots site or brand, if you like a free demo. Too many people get upset or confused by rewards of welcome when they climb without first looking down. Often they left wondering why they were unable to remove their winnings from the bonus money.
We are not against any kind of welcome bonuses. We just want to understand them by the players. After all, if the welcome reward and any wagering conditions are gone, the real fun begins.
