How to Claim the Welcome Bonus Without a King Casino Promo Code
The process is pretty simple overall, but here’s a breakdown to make sure nothing gets missed:
1. Register and Opt in
Click one of the banners on this page to head to King Casino and complete the sign-up form. One thing to watch for is that you need to tick the opt-in box to receive the welcome offer. If you skip this, the bonus won’t activate.
2. Complete KYC Verification
As part of UKGC regulations, you’ll need to complete Know Your Customer (KYC) checks before you can withdraw any winnings after meeting the other requirements. This usually involves uploading photo ID, proof of address, and possibly a payment method verification. The process can be completed via your account dashboard and is best done early to avoid delays later on.
3. Make Your First Deposit (£20+)
After registration, make your first deposit of £20 or more. To trigger the welcome bonus, your deposit must be wagered on Big Bass Splash within seven days. Once completed, you will receive 20 free spins on Big Bass Splash, with no wagering requirements on any winnings. The spins must be used within 24 hours of being credited.
4. Didn’t Receive Your Bonus?
If the bonus or spins don’t appear, customer support can step in. The bonus is meant to apply automatically, but if there’s an issue, support is listed as the next step.
Understanding the Important Bonus Terms
These are the terms we paid the most attention to while testing the offer. King Casino does a decent job of outlining the key points on their site, but we’ve summarised them clearly below.
Wagering Requirement
The welcome bonus does not have a wagering requirement on winnings from the free spins. You only need to wager your initial deposit of £20 on Big Bass Splash within seven days to trigger the 20 free spins. Once this is completed, any winnings from the free spins are yours to keep with no further playthrough.
Time Limit
You must complete the deposit wagering requirement within 7 days of making your qualifying deposit. The free spins themselves must be used within 24 hours of being credited, or they will expire.
Extra Spins: Expiry and Withdrawal Cap
The 20 free spins are locked to Big Bass Splash and expire 24 hours after they are credited. There is no wagering on winnings, so the full amount you win is withdrawable, and there is no withdrawal cap.
How to Get Value from This Offer
We’ve gone through the process ourselves, and here are a few things that can make a difference when using the King Casino welcome offer.
⏳ Use your spins before they expire
Extra spins expire just 24 hours after they’re issued. It’s easy to forget about them, so plan your deposits for a time when you’ll actually have a chance to play.
🎰 Stick to eligible games
This welcome offer is specifically tied to Big Bass Splash. To qualify, you must deposit and wager £20 on this game within 7 days. The free spins are also locked to Big Bass Splash and won’t be valid on other titles.
📅 Complete wagering within 7 days
After making your £20 deposit, you must wager that amount on Big Bass Splash within 7 days to trigger your 20 free spins. If the wagering requirement isn’t completed in time, the spins won’t be awarded.
🛡️ Set up responsible play tools
You’ll find deposit limits, session timers, and reality checks under your account settings. These tools are easy to set and useful for staying in control, especially if you plan to play over multiple days.
✅ Consider verifying early
Although KYC isn’t part of the deposit step, getting verified early avoids hold-ups later, especially if you’re aiming to withdraw. It’s a one-time process and keeps everything running nicely.

A Closer Look at the Free Spins Slots
The 20 free spins in King Casino’s welcome offer are tied specifically to Big Bass Splash, a popular fishing-themed slot that’s known for its bright design and bonus-driven gameplay. Since the spins are locked to this game, here’s what you can expect when they’re credited.
Big Bass Splash
Big Bass Splash is one of the games in the popular Big Bass series. It uses a standard five-reel, 10-payline setup and is filled with bright fishing-themed symbols; think tackle boxes, fish, and a fisherman character who plays a big role in the bonus features.
How the Free Spins work
To trigger Free Spins, you need to land three or more Scatter symbols anywhere on the reels. Once you’ve gotten in on the bonus round, the fisherman becomes your best friend, every time he appears, he collects the cash values displayed on any fish symbols on screen and adds them straight to your winnings. The more fishermen that show up, the more you can collect. They can also increase your multiplier as the round goes on, which can seriously bump up what you walk away with.
Volatility and RTP
Big Bass Splash sits in the medium volatility range. That means you can expect a decent mix of smaller, more frequent wins alongside the bigger payouts that come from the bonus round. The return to player (RTP) usually sits around the mid-96% mark, though this can vary slightly depending on which casino you’re playing at.
Before you use your welcome spins
Since your free spins are linked to this specific game, it’s worth getting a feel for how everything works before you activate them. Just keep in mind that your spins need to be used within 24 hours of being added to your account, and any winnings you make come with 0x wagering requirements, as long as you’ve followed all the terms and conditions.
Play responsibly
King Casino has a range of tools to help you keep control of your play, including deposit limits, session reminders, and reality checks. You can find all of these in your account settings whenever you need them.
King Casino Licensing and Consumer Protection
As of 23 September 2026, the Gambling Commission’s public register links King Casino to Jupiter Gaming Limited, which holds an active remote casino licence. A licence puts rules on the operator, but it doesn’t make gambling risk-free, and it doesn’t guarantee your funds are protected if the company goes bust.
Operator and Regulatory History
Jupiter Gaming Limited appears on the Gambling Commission register under account number 67098. Its remote operating licence, 067098-R-341149-003, covers casino activities and has been active since 28 August 2025.
Before that, King Casino ran under AG Communications Limited’s licence, according to published reports. AG Communications was fined £237,600 for anti-money-laundering failures in November 2022, and in March 2025 it agreed a separate £1,407,834 regulatory settlement after the Commission found further anti-money-laundering and social responsibility failures. Both actions concerned AG Communications, not Jupiter Gaming.
An Generous Offer Backed by Clear Terms and Regulation
We’ve seen a lot of casinos hide their welcome offers behind codes or time-sensitive links. King Casino doesn’t do that. The welcome deal is available directly through the site, with no promo code needed and everything outlined clearly. That’s not to say it’s the most high-value offer in the UK market, but it’s easy to claim, well structured, and supported by a reputable license. Just remember to read the terms, stay within the limits, and make use of the tools available.
