What are Slot Machine Bonuses?

The term “slot bonuses” refers to any bonus offers from online casinos that benefit you in some way, i.e. increase the value of the game itself, your chances of winning, or your account balance.

What Kinds of Slot Bonuses Are There?

From the definition above, it is clear that slot bonuses include not only one-time awards, but also various seasonal promotions, contests, etc. The most famous slot machine bonuses include the following:

  • Free Money (No Deposit Bonus for Registration) on Slots

    Free money (no deposit bonuses) is one of the bonuses that await you at online casinos. This is because free money is most often given to players by online casinos for signing up to their online casino. Some online casinos give you free money gradually as you go through the registration process (for example, £5.00 for completing the registration form, £10.00 for verifying your identity and £10.00 for connecting a payment method), while some send you money to your account at the very end of the registration process.

    Given the above, free money, along with free spins, are the most popular casino bonuses (especially if the casino credits it to your account without requiring a deposit).

  • Free Spins – Bonus on Slots

    The second most popular casino bonus on the slots is free spins awarded by casinos on various occasions.

    Some casinos offer them for signing up, others offer them for the first deposit of money. Virtually all online casinos then intersect in offering seasonal free spins, where they award free spins on a selected day or several related days to all their existing players.

    What slots are free spins for?

    Bonus free spins at online casinos are usually tied to a selected slot machine or a selected group of slot machines.

    In addition, you may come across special promotions where an online casino selects a group of slot machines for free spins seemingly at random, or by game theme, for example. In this case, you can then get free spins on:

    • Fruit slots
    • Joker slots

    How do you find out which slots the free spins bonus is available on?

    For information on which slots the free spins are available on, see the exact bonus terms and conditions. Some casinos make this information available directly in the promotional banner for the promotion, other casinos list it in the News section and others have it listed in the Game Plan for the promotion itself. We recommend that you look for this information before you take a chance on a free spin promotion. This is the only way to avoid any unpleasantness.

  • Slots Bonuses for Your First Deposit

    As the name of these bonuses suggests, deposit (welcome) bonuses are linked to your deposit of money. This can be the first deposit of money (part of the welcome bonus) or any additional deposit of money (the reload bonus).

    Deposit bonuses on slots can be subject to the insertion of a promo code. This code is entered during registration or when depositing money. If you forget to insert the promo code, you will lose the bonus (or you can redeem it on your next deposit in the event of a reload bonus).

  • First Deposit Bonuses

    Deposit bonuses on the first deposit of money are available in the majority of online casinos. As part of this bonus, casinos will add bonus money to your first deposit, usually to the value of 100%. However, as this is usually a larger sum and this money is released gradually as you play (there is a condition called ” spinning” attached to it).

  • Reload Bonuses on Slots

    Reload bonuses are offered on certain additional deposits of money. Reload bonuses are awarded as part of certain special bonus promotions or individually based on the behaviour of the customers themselves. With some reload bonuses, casinos will try to entice you back to the game in case you haven’t played for a long time, or on the other hand encourage you to continue playing when you are not doing too well.

    Most often, reload bonuses are awarded when a new game or group of games is launched to encourage customers to try them out. Whatever the reload bonuses are, they often need to be activated using promo codes. You can get the promo code in the information banner or maybe in the email that the online casino sends you.

    Reload bonuses can vary in amount and value. The value of the reload bonus can be given as a percentage (e.g. 50%, 100%), or it can be quantified directly in money (e.g. the “Deposit £5.00 get £2.50 extra” promotion).

  • Regular Deposit Promotions

    Regular deposit promotions are organised by online casinos at weekly or monthly intervals. These promotions offer you a reload bonus on selected games with a pre-determined promo code. Regular deposit promotions are held, where they are called “Game of the Week”. This promotion will earn you a few hundred crowns each week when you deposit and play on your chosen game of the week.

  • Loyalty Bonuses on Slots

    While loyalty programs don’t bring instant money to the table like free money and free spins do, they are still a very good way to increase your winnings at an online casino.

    With a loyalty program, you collect points for every spin you make in the casino. When you accumulate points, you can redeem them for various rewards such as free spins, or play money. Some online casinos also offer discounts to selected shops or promotional items.

  • Casino Tournaments Not Just on the Slot Machines

    Casino tournaments are regularly held tournaments in casino games, usually on slot machines. The goal in a casino tournament is to collect the highest number of points and to place as high as possible in the leader board. There are prizes, usually in the form of cash, for a select number of the top players. Casino tournaments are thus a great way to evaluate your online casino play.

    Casino Tournament Rules

    Casino tournaments are usually themed. This means that they apply to a selected game or a selected group of slot machines. Casino tournaments are also conducted according to several different rules. These give us an indication of how players will be ranked. Most often, players are ranked according to:

    • Total bets
    • Number of spins made
    • Highest winnings
    • Sum of all wins

    Casino tournament prizes

    Casino tournaments also have different prize pools, i.e. rewards. The total amount of some prizes starts at £1,000, but there are also tournaments with a prize pool of £12,500. Of course, the better funded the tournament, the better the prizes are for individual winners.

    Duration of casino tournaments

    All casino tournaments are announced for a predetermined period of time, for example, from Monday to Friday. Only the games that are played during this time are counted in the best-player rankings. For casino tournaments, it pays to focus on the duration of the tournaments. If you know in advance that you will only have a minimum amount of time to play the slots in a given period, and if it’s a “sum of all spins” game, it’s kind of a given that good results will be lost in advance.

    Where can you find more information about casino tournaments?

    For more information about casino tournaments (which machines are used in casino tournaments, what rules are used to evaluate them, or what prizes are offered), you can always check the description of the tournament along with the option to buy-in.

  • Jackpots – Slots Only Bonus

    Casino jackpots can be considered as a small bonus when playing slots. Jackpots are consistently generated amounts from slot machine play by all participants, which can then be won with a single hit combination. Jackpots usually bring winnings of many times the stake and are therefore a really welcome change.

    There are essentially two types of jackpots in licensed online casinos. These are:

    • Jackpots offered by slot machine manufacturers
    • Jackpots offered by the casinos themselves (all-casino jackpots)

    Jackpots from slot machine manufacturers

    The title implies that the slot machine manufacturers themselves provide these jackpots for their games in online casinos. The jackpots are therefore linked to a group of games from one manufacturer, and can only be won by playing on their machines.

    Jackpots from slot machine manufacturers may or may not be subdivided into levels. If the jackpots are layered, you will usually find bronze, silver and gold jackpots, or even platinum jackpots. Each of these jackpots then has a different value and is accumulated separately from the volume of all the games played on the slot machines from one manufacturer.

    Slot machine jackpots from online casinos

    These jackpots are rarer, but you can also find them in UK online casinos. The value of the jackpot from online casinos is accumulated from the volume of all spins made on all slot machines within that online casino. It further implies that these jackpots can be hit on all slot machines in a given casino without exception.

    How to redeem slot bonuses?

    Slots bonuses are applied in different ways. In some cases, they are credited to your account automatically by meeting the conditions of the selected bonus (for example, the first deposit of money of a certain value).

    Some bonuses are activated by entering a bonus code when you register or deposit. Other bonuses, especially seasonal free spins, are activated by visiting the selected slot machine on a given day and accepting the bonus offer in the pop-up window.

    Finally, there are bonuses that need to be confirmed in the online casino environment by clicking on the bonus activation button.

Can you redeem slot bonuses on your mobile?

Of course. Online casinos don’t differentiate between customers who use slots on a computer and those who play on a mobile device – either via the casino mobile app or the mobile browser. The bonuses offered are the same in the vast majority of cases. Therefore, it doesn’t matter which platform you choose to receive your bonus.

What are the terms and conditions of slot bonuses?

Slot bonuses come with various terms and conditions that need to be met in order to receive the bonus (either part or all of its value). The basic requirements for claiming a slots bonus include:

Wagering requirments

Number of spins

The number of spins determines how many times you have to wager bonus money (whether credited instantly or won in free spins, etc.) into the game before it is no longer subject to any conditions and therefore truly yours.

The higher the multiplier, the more times you have to put money into play and the more likely you are to lose everything. With this in mind, bonuses with no wagering requirements are the most advantageous, followed by bonuses with the lowest number of wagering requirements.

Bonus Time conditions

Time limit

The time limit determines the timeframe in which you must complete all the bonus conditions. If you don’t meet the bonus conditions within the time limit, the casino will pay you only part of the bonus or nothing at all (depending on the requirements).

slot-reels

Selected games

Some bonuses can only be claimed on selected games or on specific slot machines. If you choose slot machines other than those specified, your deposits will not count towards the wagering requirement. In short, you will be playing just for fun.

Tip: In addition, of course, you must also meet the terms and conditions for the initial activation of the bonus, such as entering a bonus code or making a deposit of a predefined minimum amount, etc.

What is the best way to redeem slot machine bonuses?

What is the best way to redeem slot bonuses, ideally in their full amount? This is the most common question of every casino customer. To be honest, there is no guaranteed formula for selecting bonuses in their full amount, because online slots are completely random and so everything depends not only on technique, but also on chance. However, there is still a method that is guaranteed to increase your chances of withdrawing your bonus in its full amount. Follow the steps.

  • Select the bonus that’s right for you

    In all honesty, some casino bonuses are really hard to pick, if only because of the terms and conditions attached to them. You increase your chances of claiming a slots bonus just by choosing the right bonus. As mentioned above, the fewer conditions attached to the bonus, the less work you’ll have to do to earn the bonus and vice versa.

    However, you will also increase your chances of collecting the bonus by selecting the right bonus for your gameplay. Unless you are really just a casual player, it is hard to imagine that you would be able to meet the condition for a spin bonus (for example, 30x). In that case, you should focus more on free money or free spins. On the other hand, if you frequent slots more often, then you should focus on deposit bonuses or loyalty programs that can bring you significantly more money.

  • Customising the bet amount

    If the bonus conditions include a wagering requirement, then you probably can’t hope to meet it by going all-in on every spin (i.e. putting your entire balance into play). This approach is downright gambling in its most basic form and goes against both the terms and conditions of proper casino money management and common sense itself.

    When trying to wager money, you must try to stay in the game as long as possible, which in turn means adjusting your bet to your financial capabilities. If you’ve only transferred a few pennies to the casino, then you should play for the lowest possible amount. Being careful with your money will allow you to suppress variance and increase your chances of staying in the game until the casino releases the full bonus.

    Tip: Choose games with low volatility, i.e. games that produce smaller but more frequent (more likely) wins. This will further help you reduce variance, giving you a better chance of staying in the game until the last penny of your bonus is withdrawn.

  • Meet the time limit

    In many cases, there is a time limit attached to casino bonuses. The time limit indicates the deadline by which all bonus conditions must be met. If you don’t meet the conditions within the time limit, the bonus will be forfeited in full or prorated. Either way, it’s very frustrating.

    Therefore, always check when claiming a bonus when you need to meet the bonus conditions and then adjust your play accordingly. On the other hand, you shouldn’t restrict some of your other activities or force yourself to play because of the bonus. In casinos, more than anywhere else, the saying “everything in moderation” always applies.

  • Beware of receiving other bonuses

    Online casinos can offer several types of bonuses at the same time. In the vast majority of cases, bonus offers are not compatible, so you are unable to fulfil the bonus conditions of more than one bonus offer.

    So if you accept another bonus offer, the casino may automatically start counting the amount of money you wagered towards another bonus and you will miss the money you wagered somewhere else. This is really frustrating and you should always think carefully before accepting or declining an offer.
