King Billy Casino launched in 2017 and has since become a recognisable name in the international online casino space.
It is best known for its enormous game library, ranging from thousands of slots to an unusually deep selection of jackpot titles and live dealer games.
The site is also notable for its crypto-friendly approach, giving players the option to deposit and play using digital currencies.
King Billy Casino is operated by Dama N.V., a Curaçao incorporated company that holds an active licence from the Curaçao Gaming Authority (OGL/2023/174/0082).
The operator manages a large portfolio of international casinos, including Spinrise Casino, Winz Casino and Slotlords Casino.

The overall King Billy Casino bonus value is strong, particularly the combined €2500 cap and the 250 free spins. The 30x wagering requirement is competitive.

King Billy Casino runs a steady range of ongoing promotions for existing players, including weekly free spins, tournaments and a weekly cashback deal depending on activity and account level.
Regular promotions run throughout the week, giving returning players consistent rewards beyond the welcome package.
All players are automatically enrolled into their VIP program - VIP Court - a 10-tier loyalty system where deposits earn Royal Score points, unlocking cashback boosts, level-up bonuses and King’s Coins that can be exchanged for cash or bonuses.
King Billy Casino accepts Visa, Mastercard, Skrill, Neteller, EcoPayz, Jeton, MuchBetter, Paysafecard, Apple Pay and bank transfer, alongside crypto methods such as Bitcoin, Litecoin, Tether and CoinsPaid.
The minimum deposit is €20, while withdrawals start from €40. Crypto deposits begin at 0.0002 BTC.
Withdrawals are reviewed Monday to Friday rather than instantly, though supported e-wallets and cards typically provide faster processing once approved.
King Billy Casino completes full verification when a player requests their first withdrawal. You will need to provide a colour photo of a valid ID, along with proof of your payment method, such as an e-wallet screenshot, bank statement or a masked copy of your card.
The payments team may also request proof of address or, in some cases, additional documents like a selfie with your ID or proof of funds. Verification is processed once all documents have been reviewed.
King Billy Casino offers more than 15,000 games across slots, live dealer tables, jackpots and classic casino formats.
The King Billy Casino slots collection is exceptionally large, with over 10,500 titles from 85 software providers. This includes major studios such as Games Global, Pragmatic Play and Play’n GO, along with a broad range of indie developers.
Players will find classic three-reel slots, modern feature-packed video slots and more than 190 Megaways games.
It is one of the most extensive slot libraries available to Irish players.
King Billy Casino offers more than 2,700 casino jackpot slots in total, including over 700 progressive jackpot games.
The progressive line-up spans major networks from Games Global, Amusnet, Fazi, Playtech, Red Tiger, NetEnt and the iconic Mega Moolah series, giving players access to an exceptionally broad mix of jackpot styles and prize pools.
There are over 1,050 live dealer games powered by Evolution Gaming and Pragmatic Play Live, supported by 10+ additional game providers.
The range covers live roulette, blackjack, baccarat and poker, along with game shows, Sic Bo, sports-themed tables and alternative live formats.
With such depth, players can easily find a table that suits their preferred betting style and pace.
King Billy lists more than 1,300 classic casino and RNG table games.
While this includes some overlap with live titles, it still provides a strong set of digital roulette, blackjack, baccarat, video poker and speciality games.
These offer a quick, low-friction alternative to live dealer play.
Live chat at King Billy Casino is available 24/7.
When I tested it, the initial AI assistant was almost useless, offering only a handful of preset topics with no ‘other’ option to type my query. I had to click an unrelated category to reach a real agent.
Once connected, there was no wait time. The support agent responded quickly, understood my issue straight away and was genuinely helpful. They just need to refine the initial AI consultation.
King Billy Casino offers a solid range of responsible gaming and gambling tools, including deposit limits, loss limits, wager limits, cooling-off periods and full self-exclusion.
These can be adjusted through your account or with support assistance.
However, the casino does not provide behavioural monitoring tools to identify signs of harmful play, which is a noticeable gap compared with other advanced online casino providers.
Here are a few things to consider before signing up:
Currently, King Billy Casino does not offer a mobile app.
Withdrawals are not instant and are only reviewed Monday to Friday. Requests made after Friday afternoon will not be processed until the following week, which is poor for a 24/7 online casino.
The minimum withdrawal amount is €40, which is higher than many Irish-facing casinos and may not suit lower-stakes players.
King Billy online casino offers a very strong welcome package, including a high-value crypto alternative, which will appeal to both traditional and cryptocurrency players.
The game library is exceptional, with one of the largest slot and jackpot selections available to Irish players, plus a deep live casino offering.
However, the lack of a mobile app and the absence of instant withdrawals may put some players off.
Even so, King Billy remains a compelling option for anyone seeking scale, variety and flexible bonus options.
