Which slots bonuses you should avoid?

The first thing you need to know about different slot bonuses, or any casino bonuses for that matter, is that although bonus always sounds great, not all bonuses are really beneficial for you. Why? The main reason is that all bonuses have certain limitations, the most important ones are the playthrough and the maximum cash out. (Don’t worry, we will explain in a second).


So what does maximum cashout means? Exactly as it sounds- it means that if you take the bonus, there is a limit to what you can actually withdraw. For example: you used a $/£/€ 100 bonus with maximum cashout of $/£/€ 500. You hit the jackpot and win 25,000 $/£/€. Congrats! Now you go to the cashier to withdraw your winnings- the amount that you will get is not 25k, but the maximum cashout amount, which is 500. Bummer…

Rule #1: Do not take bonuses with maximum cashout limitations. The only exception is in case you are getting them for free, like a $10 casino no deposit bonus.

What is PlayThrough

Second important parameter of slots bonuses is the playthrough. Playthrough, also refered as wagering requirements (PT or WR), is the amount you need to bet to “clear” the bonus, i.e., before you can cash out. When you get a bonus from a casino, you cannot cash it out immediately. If that was the case, it would make no sense for the casino to give it to you. You need to bet a certain amount of $/€/pounds before it becomes cashable. That amount is called the playthrough. The most common way to calculate this amount is by multiples of the deposit + the bonus (b+d).
For example if the playthrough is 25 times (b+d) and you make a deposit of $100 and get $200 bonus. The playthrough will be (100+200)*25 = $7,500. It means that you need to make $7,500 worth of bets before you can withdraw your winnings. Therefore, when we are looking for a bonus, we want the lowest possible playthrough.

Rule #2: Best Slots Bonuses have low playthrough

Additional details that you should check when redeeming casino slots bonus is the games that you are allowed to play: some slots bonuses are open for other games as well, blackjack for example, while some are limited to different types of slot machines only, like video slots, 3D online slots, classic slots, bonus slots, etc… It’s very important to know which games you can play while using the bonus- in many online casinos, if you break this rule, your winning will be negated and you will have to start all over again (with your original deposit) and it doesn’t matter if you just played few hands of blackjack- breaking the rule is breaking the rule.

Cashable vs Non Cashable

Most online casino bonuses are given only for wagering purposes. Meaning that after completing the bonus terms, the casino will take back the bonus amount that you were previously given. These bonuses are called phantom, sticky or simply non-cashable. This is the industry default and unless it’s stated otherwise, you should refer to bonuses as non cashable. Cashable bonus, as the name implies, are those that you can keep and withdraw after completing the wagering requirements. Please check our Cashable Bonuses page for more details.

Rule #3: If you are playing on a bonus that is slots only, stick to slots. If you like to mix, slot machines, blackjack, video poker- please choose a bonus that is open to these games as well.
In the table above, we state which bonuses are limited to slots only and which are open to other games as well, so pick the one that suits you best.

Best Slots Bonuses – Summary:

  1. No maximum cashout rule.
  2. Check if the bonus is cashable.
  3. Look for bonuses with lowest playthrough (wagering requirement)
  4. Know which games you can play and which games are restricted.

We have a lot more to say about best slots bonuses and the ways to use them to increase your winnings, but you are probably eager to start. Just remember the rules we listed here and you are good to go. Choose one from the table above and have fun.

Best Bonus Slots Games in 2021

The great thing about playing slots on the internet is that they tend to pay out more than their land-based counterparts. Because there is less maintenance and not as much overhead in running an online casino, payouts for online slots can come close to 98%.

One way casinos pay back to their slot players is through bonus slots. There are a number of different types of bonus slots available, and some are better than others, so it helps to know what you are looking for in order to maximize your playing time and bonus cash.

The most obvious types of bonus slots out there are jackpot slots. Some jackpots slots have a set amount that they pay out if you hit the jackpot combination.

For instance, hit a red, a white, and a blue seven playing Sevens & Stripes at Cherry Red Casino and you have hit the bonus slots jackpot worth 10,000 coins.

Another type of jackpot bonus slots are random progressive jackpot. Many sites have bonus slots that are linked to a progressive jackpot. These random progressive bonuses pay out on certain slot machines and other casino games that are specially designated as being part of the random jackpot.

All of the games involved in a random progressive jackpot are linked. What this means is that any time someone is playing one of these games, no matter which game or what amount they are playing, they are paying into the jackpot and have a chance of hitting it big.

Coolcat casino. Random bonus slots jackpots are payed out quite often since there are so many games involved and they also build up quite fast. The payouts for these bonus slots are usually in the tens of thousands of dollars and sometimes over a hundred grand!

The final and most impressive type of bonus slot is the progressive jackpot slot machine. Progressive jackpot slot machines will often have payouts well in excess of a $1 million. In fact, some sites, like Slots Oasis Casino, have several progressive slot machine jackpots all over a cool million.

The reason these jackpots get so large is that they are usually shared over a network of sites and they are generally for one machine only. Therefore they are payed into by a large number of people, but are not hit as often as random progressive jackpots, which are shared among many different games.

There is one other way that bonus slots will pay out. It is sometimes overlooked but is one of the easiest and most beneficial ways to play bonus slots and to maximize your winnings. This is simply by getting a slots bonus when signing up to a new casino and making a deposit.

Some people do not even realize that most casinos will give you free bonus money almost every time you deposit. This is especially true if you are playing slots. Some sites, like the aforementioned Slots Oasis Casino, pay out huge bonuses when signing up. They offer a 400% bonus worth up to $4,000.

Other sites, like Cherry Red Casino, offer 100% bonuses worth up to $5,000, which they offer over your first three deposits! With the amount of money being offered up basically for free by these casinos it would be a complete shame not to take advantage and get a piece of the action.

You can see there are many ways for bonus slots to pay back to the players, it just depends on what you are looking for. Some bonus slots pay more often, but lesser amounts.

While others do not pay out very often, but when they do they can make the lucky player an instant millionaire! So check out our online casino reviews, find a bonus that suits you, and start playing some bonus slots today!
