Prime Casino Review: Games, Payments, and Player Experience

Prime Casino has been part of the UK market since 2005, making it the oldest brand in the SkillOnNet network. Unlike newer sister sites that push niche features, Prime Casino feels traditional: it focuses on a wide slot catalogue, a steady live dealer section, and stable payment processing that has held up over 20 years.

Attribute	Details
Established In	2005
Minimum Deposit	£10
Number of Slots	7,035
Number of Live Games	502
Security Features	20-year UKGC compliance, SSL encryption
Best Feature	Free Spins for a Year programme

The game library covers over 7,000 slots, with all the classics like Starburst, Book of Dead, and Big Bass Bonanza, plus SkillOnNet exclusives such as Secrets of the Phoenix. Its 500+ live dealer tables are powered by Evolution Gaming, with blackjack and roulette limits starting from £0.50 and climbing into the thousands for VIPs.

Payments are consistent: PayPal cleared in under 24 hours during our testing, while debit cards took 2–3 working days. For players who value quicker payouts, it’s worth comparing against fast withdrawal casinos like PlayOJO or SpinGenie.

Pros:

7,000+ slot titles, including exclusives

What Games You’ll Find at Prime Casino Sister Sites

This means you’ll find everything from simple three-reel classics to blockbuster progressives and interactive live tables. Popular names like Netent, Pragmatic Play, Evolution, and Microgaming all feature, alongside Skill On Net exclusives that you won’t see outside the network.

Across the 23 casinos, there are over 7,500 slot titles. The mix covers penny slots, branded video slots, and Megaways releases with thousands of ways to win. Players who enjoy exploring different slot platforms will see plenty of crossover with the UK’s top slot sites.

The Providers Behind the Games

The Prime Casino sister sites are built on a roster that balances household names with niche studios. Netent and Pragmatic play bring blockbuster titles, Evolution dominates live dealer content, and SkillOnNet develops exclusive games that are only available across its network.

Provider	Year Established	Total Games	Most Popular Game
Netent	1996	200+	Starburst
Pragmatic play	2015	250+	Big Bass Bonanza

Play’n GO	2005	300+	Book of Dead
Barcrest	1968	150+	Rainbow Riches

Managing Your Funds: Payment Methods Across Prime Sister Sites

All Prime Casino sister sites use SkillOnNet’s central banking system. This setup keeps things consistent: the same limits, fees, and withdrawal rules apply across the 23 casinos.

Deposits start from £10 on most methods, and payouts are generally reliable, though the speed depends heavily on the option you choose.

Payment Method	Deposit Range	Withdrawal Time	Monthly Limit	Available At
Visa Debit	£10-£10,000	1-3 days	£30,000	All sites
Mastercard	£10-£10,000	1-3 days	£30,000	All sites
PayPal	£10-£5,000	0-24 hours	£30,000	Selected sites
Skrill	£10-£5,000	0-24 hours	£30,000	Most sites
Paysafecard	£10-£1,000	N/A	N/A	All sites
Apple Pay	£10-£10,000	1-3 days	£30,000	20+ sites
Bank Transfer	£20-£50,000	3-5 days	Unlimited	Selected sites
Trustly	£10-£10,000	Instant-24h	£30,000	Most sites

From our testing in September 2025:

PayPal and Skrill were the fastest, clearing in under 24 hours. These are your best picks if you care about quick access to winnings, similar to what you’d find at fast withdrawal casinos.
Visa and Mastercard took 2–3 working days, which is standard for UK casino sites.
Bank transfers allowed much higher limits (up to £50,000), but withdrawals averaged 3 to 5 days.

There are no hidden fees across the network, but your first withdrawal does require a completed KYC check. Once that’s done, payments are smoother, and priority processing kicks in if you’re flagged as a VIP.

VIP and Loyalty Rewards at Prime Casino Sister Sites

The Prime Casino sister sites don’t follow the usual tiered loyalty ladders. Instead, rewards are tailored to how much and how often you play. High-value players get contacted directly by account managers, while consistent smaller-stakes players can still unlock perks like cashback and faster withdrawals.

This personalised approach sets them apart from traditional VIP casinos.

What you can expect as a VIP or loyal player:

Personal account manager for higher-tier players
Faster withdrawals, sometimes under 2 hours
Exclusive reload bonuses with reduced wagering
Birthday and anniversary gifts delivered automatically
Invitations to events like football matches and concerts
Increased deposit and withdrawal limits
Cashback deals of up to 20% weekly

Overall, the system rewards activity without making you chase rigid tiers. It works well for players who prefer benefits to arrive naturally instead of grinding for points.

Getting Help at Prime Sister Sites – Support Channels

One thing players often ask before signing up is how reliable the support team is. Across all Prime Casino sister sites, the setup is largely the same because Skillonnet runs the network centrally. That means the quality of help you’ll get doesn’t depend much on which casino you choose, but more on how you prefer to contact them.

Channels	Found At	Response Time	Biggest Pro	Biggest Con
Live Chat	All sites	30 seconds – 2 minutes	Fastest support option	Queue delays at peak hours
Email	All sites	4–24 hours	Detailed answers	Slower for urgent issues
Phone	Selected sites	1–5 minutes	Direct resolution with an agent	Limited availability
FAQ Section	All sites	Instant	Covers most common issues	No help with account-specific problems

For most UK players, live chat is the quickest and most reliable. But if you’re dealing with account restrictions, verification checks, or anything that needs paperwork, email is usually the better route. The phone option works if you prefer talking to someone directly, though it’s only active on selected brands.

The Company Running Prime Casino Sister Sites

All Prime Casino sister sites are owned and managed by Skill On Net Limited, a company that has been active in online gambling since 2005. Headquartered in Cyprus with offices in Malta, it has built a strong reputation in the UK market for running multiple brands under one licence.

Today, it operates more than 40 UK-licensed casinos, including PlayOJO and Lord Ping, making it one of the largest Skill On Net casino groups.

Our Method in Action: How We Evaluate Prime Casino Sister Sites

Every Prime Casino sister site we feature has been tested first-hand by the KingCasinoBonus team. We don’t just read the terms and conditions: we deposit real money, play the games, and request withdrawals to see how each site actually performs for UK players.

This way, the reviews are based on real experiences rather than marketing claims.

Here’s how we do it:

Open a new account with verified UK details
Deposit £50 using Visa, PayPal, or Skrill
Claim the welcome bonus and track the wagering rules
Play 20+ games including slots, jackpots, and live tables
Request a £100 withdrawal to check payout speed
Contact support on live chat and email to see how helpful they are
Verify the UKGC licence and responsible gambling tools
Test mobile play on both iOS and Android

Our thorough review process gives us a fair picture of how each casino performs and lets us compare the 23 sister sites side by side.

F.A.Q.

Can I transfer funds between different Prime Casino sister sites?

Direct fund transfers between Prime Casino sister sites aren't possible, as each casino operates with separate wallets despite sharing the SkillOnNet platform. You must withdraw funds from one site and deposit them into another, following standard processing times. However, some sites offer faster internal processing for players active across multiple SkillOnNet brands.

What exclusive games can I only find at Prime Casino sister sites?

Prime Casino sister sites feature exclusive SkillOnNet-developed games unavailable at other UK casinos. These include Secrets of the Phoenix Megaways, Tiki Island, Wild Dodo, and various Daily Free Games like Tiki's Catch. PlayOJO offers modified versions of popular slots with removed wagering requirements. The network also provides exclusive live dealer tables at selected sites, particularly at Genting Casino.

How do I self-exclude from all Prime Casino sister sites at once?

Self-exclusion across all Prime Casino sister sites requires contacting Skill On Net Limited directly, as GAMSTOP registration automatically blocks access to all 23 casinos in their network. Individual site exclusions won't prevent access to other SkillOnNet brands. For immediate network-wide exclusion, send an email with your details, or register with GAMSTOP for comprehensive UK gambling site blocking that includes all Prime Casino sister sites.

Which Prime Casino sister sites offer no deposit bonuses?

Several Prime Casino sister sites provide no deposit bonuses to new UK players in 2025. SpinGenie, Ice36, and Mega Casino each offer 10 free spins on Big Bass Bonanza without requiring a deposit. Simba Games stands out with 25 no deposit spins on Starburst, while Lord Ping provides 25 free spins on Book of Dead.
