About Us

Founded in 2018 by a group of casino operators and game designers, GrandMaster Jack Casino was created to offer a polished, player-first gambling destination tailored for the UK market. The idea was simple: combine the best studio-quality slots, authentic table games, and smooth live dealer action with clear, dependable service. From day one we focused on design that puts players first — easy navigation, fast deposits, and a game library that keeps gameplay fresh and rewarding.

A Clear Mission: Fair Play, Real Support, Outstanding Service

Our mission is to deliver fair, transparent gaming and exceptional customer care. We enforce rigorous fairness standards across our offerings, back every promotion with clear terms, and make it easy for players to get help when they need it. Every policy at GrandMaster Jack is driven by three priorities: protect players, offer honest odds, and provide a responsive, human-first support experience.

A Massive, Curated Game Lineup from Trusted Studios

Whether you prefer spinning reels, classic table action, or live dealer tables, our library covers the full spectrum. We partner with established software houses so every title performs smoothly and looks great on desktop or mobile. Our partners include industry leaders such as Microgaming (Apricot), Evolution Gaming, NetEnt, Play’n GO, Big Time Gaming, and Quickspin, among many others — ensuring variety, innovation, and high production values. Check out detailed spotlights on fan favorites like Kitty Cabana Slots and Ares: The Battle of Troy Slots to see what game quality looks like in action.

Security You Can Trust — Payments, Privacy, Protection

We take player security seriously. All account data and financial transactions are protected using industry-standard encryption and secure protocols. We support trusted payment providers including Maestro, MasterCard, Visa, PayPal, Skrill, Neteller, PaySafeCard, MuchBetter, and ecoPayz, and we operate with rigorous compliance controls to protect your funds and personal information. If you have questions about deposits or withdrawals, our live chat and email team is ready to assist at customersupport@instantgamesupport.com.

Responsible Play — Tools and Support Always Available

Playing should be fun and sustainable. GrandMaster Jack provides practical tools to help players manage activity: deposit limits, session reminders, reality checks, and self-exclusion options. Our support team can guide you through any responsible gaming settings and point you toward professional help if needed. We encourage everyone to set personal limits and reach out when things feel out of balance.

Meet the Team: Experience Behind Every Spin

Our collective team blends deep industry knowledge with customer-focused roles: operators who design safe systems, game curators who select titles players love, security engineers who protect accounts, and a dedicated support crew available through live chat and email. Many team members cut their teeth at top gaming companies and brought that expertise here to build a reliable, enjoyable casino platform.
