About the author
Luke Clark is a Full Professor in the Department of Psychology at the University of British Columbia, the Director of the Centre for Gambling Research at UBC, and one of the most cited gambling researchers working anywhere in the world in 2026. His ResearchGate profile documents 312 publications and over 28,000 academic citations, accumulated across a research career that spans experimental psychology, cognitive neuroscience, neuroimaging, psychophysiology, and data science. Clark contributes to this publication as an independent academic reviewer with no commercial arrangement with Rainbet, its operator RBGAMING N.V., or any affiliated entity.
My reviews are not advertisements. I look at bonus terms and platform design the way I look at research methodology — with scepticism first and approval only after the evidence holds up. If a withdrawal structure serves the house more than the player, that will be in the review. That’s the deal.

Why a gambling neuroscientist reviews crypto casinos
The question I get most often from colleagues when they find out I write casino reviews is some version of “why would you do that?” The answer is the same answer I give when explaining why my research programme exists at all: because gambling products affect millions of Canadians, and the research perspective on how those products work — what makes them engaging, where the risks sit, how the design creates specific psychological effects — is almost never present in standard casino review coverage.
When a review site evaluates Rainbet’s game library, it typically notes game count, provider names, and whether demo mode works. It rarely examines the near-miss architecture built into slot machine paytables, the cognitive distortion effects of provably fair crash games’ multiplier sequences, or what Rainbet’s rakeback payment structure does to session engagement patterns. My reviews try to cover both dimensions: what’s there, and what the science says about how it works on the people using it.
Academic background and career path
Before joining UBC, I was a Senior Lecturer at the University of Cambridge in the UK, where I developed the research programme on decision-making and reward that eventually became the foundation for my gambling-specific work. I joined UBC in 2014 when the Centre for Gambling Research was established with funding from the Province of British Columbia and the British Columbia Lottery Corporation. Since then, the CGR has become one of the few dedicated gambling research centres in the world and the only one of its kind in Canada.

My research uses multiple methods simultaneously: laboratory experiments, functional neuroimaging (fMRI) to track neural reward activation during gambling-relevant tasks, psychophysiological measurement of arousal responses during slot machine play, and large-scale data science analysis of real-world gambling platform data. My laboratory has used behavioural data from the PlayNow.com platform in British Columbia to develop machine learning models that predict which players are at risk before they reach a crisis point.
Research focus: three questions that define a career
How do gambling product features create harm?
My near-miss research is probably the most widely cited strand of this work: near-misses in electronic gambling machines, where two jackpot symbols align but the third falls short, are not neutral random events. They activate neural reward circuitry partly shared with actual wins, generate stronger urges to continue playing than standard losses, and are partially engineered into slot paytables rather than being purely random by-products of the game mathematics. For a platform with thousands of slots from dozens of providers, this research is directly relevant to understanding what players are engaging with.
What creates individual vulnerability to gambling disorder?
My laboratory uses neuroimaging, psychophysiology, personality assessment, and pharmacological challenge approaches to map the cognitive and neural substrates of vulnerability. Impulsivity, reward sensitivity, and cognitive flexibility in decision-making emerge consistently as partially heritable risk factors. This work matters for understanding which promotional structures — like daily login bonuses or escalating race prize pools — are likely to be more engaging for people in specific vulnerability profiles than for the general population.
Can online data identify at-risk players proactively?
My group has published work using PlayNow.com’s actual player data to show that machine learning models can predict self-exclusion and problem gambling status with meaningful accuracy from session patterns alone — before a player reaches the point of seeking help. Whether that data is used proactively for player protection or only retroactively for compliance purposes is one of the most important questions in Canadian online gambling in 2026.
Editorial roles and publication record
I serve as Assistant Editor at Addiction — one of the highest-impact peer-reviewed journals in the substance use and behavioural addiction field — and at International Gambling Studies, the primary dedicated academic journal in gambling research. My ResearchGate profile at researchgate.net/profile/Luke-Clark-2 lists 312 publications as of 2026 across journals spanning neuroscience, addiction medicine, psychiatry, public health, and gambling-specific outlets.
In 2015, I received the Scientific Achievement Award from the National Center for Responsible Gaming. The recognition reflects the broader field’s assessment of a research contribution that has influenced clinical practice, regulatory policy, and game design standards across multiple jurisdictions.
What my reviews cover that standard casino reviews don’t
When I review Rainbet or any other platform in this series, the structure follows the standard review categories — licensing, games, bonuses, banking, VIP programme, responsible gambling tools — but the analytical layer underneath is different from what commercial review sites produce. The combination of provably fair technology, instant crypto withdrawal processing, and frequent rakeback payments creates an engagement environment that I examine through the lens of what behavioural research says about reward immediacy and gambling persistence. The licensing structure gets evaluated not just as a compliance checkbox but as the mechanism that determines what consumer protection applies when something goes wrong.
