Spin King Casino Bonus — 100% up to £100 for New GB Players
Spin King keeps its welcome offer simple, and we like that it does not over-promise: new GB customers get a 100% match on their first deposit, up to a maximum of £100 in bonus funds. To qualify you opt in at sign-up and deposit at least £20 within 31 days, and the bonus is worth one times your deposit up to that £100 cap — so a £20 deposit returns £20 bonus, and you would need to deposit £100 to claim the full amount. The wagering is refreshingly light for this market: you play through the deposit and bonus together 10 times if you clear it on selected slots, or the equivalent of 5 times on bingo, within 30 days before withdrawing winnings, and the most you can win from the bonus is capped at £300. Note the three different numbers so you do not mix them up: the minimum qualifying deposit is £20, the maximum bonus is £100, and the maximum bonus win is £300. One important honesty point — this single offer is shared across all of Happytiger's sites on the same licence (Spin King, Happy Tiger and their siblings), so you can claim it once across the group, not once per site. You will also see plural "SpinKings" pages advertising far larger figures such as £500 with 100 spins or £1,000 with 150 spins; those do not match the licensed casino's actual offer, and we would treat them as inflated affiliate or copycat claims rather than the real terms.
How the Spin King welcome bonus works
Opt in at sign-up and deposit at least £20 within 31 days of registering; the welcome bonus is for new GB customers only and is one offer across all Happytiger sites on the same licence
You receive a 100% match equal to your deposit, up to a maximum of £100 in bonus funds — deposit £100 to claim the full amount, or less for a proportionally smaller bonus
Play through deposit and bonus together 10 times on selected slots, or the equivalent of 5 times on bingo, within 30 days — light terms by UK standards, but read the full T&Cs first
Winnings from the bonus are capped at £300; withdrawing your deposit or its winnings before completing the wagering voids the bonus and any bonus winnings, so clear it first
How to claim it
- Register a Spin King account at the genuine, UKGC-licensed site spinking.co.uk — not a plural "SpinKings" mirror — and opt in to the welcome offer at sign-up.
- Make a first deposit of at least £20 within 31 days to trigger the 100% match up to £100 in bonus funds.
- Wager deposit and bonus together 10x on selected slots (or 5x on bingo) within 30 days, keeping the £300 maximum bonus win in mind.
- Complete the standard KYC identity check before withdrawing; because one offer covers all Happytiger sites, you can only claim this welcome bonus once across the group.
The terms that matter
For a UK casino this is a clean, modest offer rather than a headline-chasing one, and that is a point in its favour. The essentials: new GB customers only, opt in at sign-up, minimum qualifying deposit £20 within 31 days, 100% match up to £100, wagering of 10x on slots or 5x on bingo across deposit and bonus together within 30 days, and a £300 cap on bonus winnings. Because Spin King shares one welcome offer across all of Happytiger's licensed sites, you cannot stack it by signing up to each sister brand. What matters just as much is the context we verified elsewhere in this review: Spin King runs on a genuine UK Gambling Commission licence (account 57641, Happytiger ApS), which means the bonus sits behind real regulation, dispute resolution and player protection. That is the opposite of the inflated "SpinKings" mirror offers and the unrelated offshore "SpinKing" with fake licences — so if you are going to claim a Spin King bonus, make sure you are doing it on the licensed site and reading these actual terms, not a copycat's numbers.

FAQ
How big is the Spin King welcome bonus?
It is 100% up to £100 for new GB players on a first deposit of at least £20. The bonus equals your deposit up to a £100 cap, so you would deposit £100 to claim the full amount. Wagering is 10x on slots or 5x on bingo over 30 days, with a £300 maximum bonus win.
What is the wagering on the Spin King bonus?
You wager the deposit and bonus together 10 times on selected slots, or the equivalent of 5 times on bingo, within 30 days before withdrawing. That is light by UK standards. The maximum you can win from the bonus is capped at £300, and clearing it early avoids voiding the bonus.
Why do some SpinKings sites show a bigger bonus?
Plural "SpinKings" mirror and affiliate pages sometimes advertise figures like £500 with 100 spins or £1,000 with 150 spins. Those do not match the licensed casino's actual 100% up to £100 offer on spinking.co.uk, so we treat them as inflated or outdated copycat claims, not the real terms.
