What to Expect From a Slots Casino Bonus

Online slot machine players get the best deal when it comes to online casino offers. Generally speaking, all welcome offers can be used to play slots games. Some casinos stipulate that you can’t use the extra cash on other casino games such as roulette and blackjack, or perhaps only a small percentage. However, it’s always wise to pay attention to the terms and conditions.

Many online casinos match your first deposit up to a specified amount. This money is often added to a separate account so you can play, but not withdraw from it. You may also have to fulfil wagering requirements to unlock the offer (and the winnings made with the bonus money). You’ll find the most common online slots bonus types below.

Free spins are often included as part of a slots welcome package. This is a popular way of enticing new players to a casino because you get a chance to try out the slots games for free while potentially winning real money. There is a slight catch; you’ll still have a number of play-throughs to satisfy even if you get lucky building a bankroll with a promotion such as this.

Online Slots Casino Bonus Codes

Bonus codes are used to distinguish offers from each other – like a no-deposit bonus for new customers or a special online slot machine bonus. Online casinos can also use these codes to determine where a new player has been referred from, and as such, partners can stand to profit from the referral. Many online slots bonus codes have the intention of enticing players to the newest slot sites, but some are incentives for existing players. They can unlock the best bonus slots casinos have to offer.

Bonuses for Specific Payment Methods

All welcome bonuses can be used to play online slot machines, which means it’s rare to find additional offers for this type of game. However, it’s possible to find promotions related specifically to the type of payment method you are using. New payment methods are springing up all over the place, and online casinos are keen to get on the bandwagon to ensure making deposits is as easy for you as possible. Offering an online slots bonus for depositing using a certain payment method is a novel way to encourage your participation. For instance, 888casino offers bonuses for paying with PayPal.

No-Deposit Casino Bonuses

A no-deposit bonus gives you the chance to sign up with an online casino and start playing without depositing money. It’s a great way to get your foot in the door and test out the slots games on offer. This tends to be the best slots welcome bonus you will find, and it’s often a deciding factor when a punter decides to join an online casino.

Double Your First DepositWith a bonus of up to £200

Full T&Cs apply. New players, £10+ deposit required. No e-wallets/prepaid cards. 30x Playthrough on Bonus and 50x on Free Spins winnings.

There are plenty of generous offers out there to choose from, but it’s important to consider the finer details when assessing which no-deposit bonus suits you best. Sometimes the offer doesn’t take the form of real cash, and you may have to wager a minimum amount of times in order to access the money.

Free Spins for Slots Games

No-deposit free spins enable you to play for free after signing up at an online casino. You can play immediately and in order to get your hands on your winnings you may need to match the minimum wagering requirements. Some casinos take a different approach by requiring you to make a deposit before getting your free spins. In this instance, the amount of free spins on offer may be determined by the amount you deposit. Wagering requirements will apply.

Wagering Requirements

Most slots signup bonuses – such as the types on this detailed list on Wikipedia – don’t mention the wagering requirements until you get down to the small print. Keep an eye out for this because it is very common. You will normally only unlock the stated bonus – and the winnings made with the cash– once you have wagered a specified amount of times. If you are told the wagering requirements are 20, and the bonus is £50, you have to wager 20 x £50 = £1000 before you can get your hands on your winnings. Additionally, some casinos insist that you must wager the combined total of the amount and the amount you deposited.

Wagering requirements also tend to apply to free spins. For example, if you win £100 using free spins, a wagering requirement of 30 dictates that you have to wager £100 at least 30 times before being allowed to withdraw your prize. You should always read the terms and conditions to avoid a misunderstanding.
