Types of Slots Bonuses
Deciding on which slot machine’s bonus is best for you, you need to compare apples with apples. New online slot games always come with enticing welcome offers which will vary in size and type. Some slots have a 200% deposit bonus while others might only offer free spins with your first deposit. Several slots even give you bonuses with no deposit required at all!
With slot bonuses, you play a lot longer with the same amount of money, giving you ample time to decide if you have found your favourite or need to move on to the next slot

Terms and Conditions for Slot Bonuses in the UK
We want our players to gamble responsibly at all times. At CasinoGuide, we will always encourage you to be aware of the terms and conditions, paying special attention to these 5 aspects.
Wagering Requirements
You will usually only find the wagering requirements in the fine print section of the terms. This usually refers to an amount of between 30x and 65x your bet, which means you need to wager 30x to 60x on your initial deposit or bonus amount awarded before you will be eligible to withdraw any winnings from said bonus amount or free spins.
Minimum Deposit Limit
Before a bonus is awarded, you usually need to make a minimum deposit of £10 or £20. With a minimum deposit, your reward won’t be unlocked unless a deposit is made with real money.
Time Limits
Sometimes, you will be required to fulfil certain actions within a time period or your bonus will be forfeited. Most of the time, it will apply to free spins, especially those awarded with no deposits.
Game Restrictions
Slot bonuses generally apply to specific and pre-assigned slot games. The idea is to promote a new slot game or the latest release of a game provider. Be sure to check regularly which slot games have slot bonuses to offer.
Max. Win Limits
Most slots bonuses come with maximum win limits, usually around £100. This effectively means you can never withdraw the jackpot if won from bonus spins or bonus cash, even if you do, in fact, ‘hit’ it!
Which slots bonuses are the best?
There is no ‘best’ slot, it all depends on what’s best for you and your specific likes and dislikes. We have listed several good slot bonuses above for you to consider.
Do I need to place a deposit for a slot bonus?
Not always, some slots come with no deposit bonuses and give you a chance to win without actually using any real money.
Are slots bonuses available on all slot games?
No, only pre-selected slot games have slot bonuses.
Can I claim slot bonuses on mobile?
Yes, most online slot games that work on a PC will work in the same way on a mobile, with the same bonuses to offer.
Can I get real money from slot bonuses?
Yes, you can. T&Cs apply for each slot, respectively.
Is it worth it to claim a slots bonus?
Absolutely! Should you utilise a slot bonus, you get a ‘free’ try at the game and can decide if it is worth wagering your own real money on.
