As competition intensifies across global iGaming markets, user experience (UX) has become one of the few remaining levers capable of materially shifting player acquisition, conversion, and long-term value. The central philosophy of how platforms should be designed has also changed. According to Moshe Adir, good design in iGaming should be invisible, trust-driven, and built around player behaviour rather than visual impact.
Speaking to SiGMA News, Adir explains that years of trial and error have shifted his focus away from flashy interfaces toward frictionless experiences that players barely notice, experiences designed to support confidence, context, and a clear path to a first-time deposit.
Creative & UX
SiGMA News: As the founder of a design agency in the space, how has your design philosophy evolved over the years?
Moshe Adir, Founder of Vegas Kings: In 1997, I thought good design meant making things look cool. I was wrong. Good design makes things work.
My philosophy has boiled down to three principles learned the hard way.
- Invisible is beautiful. The best iGaming UX is the one players don’t notice. When someone tells me our casino site has an amazing design, I know we have failed. When they tell me they just won big and can’t wait to play again, that’s success.
- Trust beats flash every time. In the early days, we made everything blink and spin because we thought gambling should feel exciting. But players deposit money with brands they trust, not brands that assault their retinas. Clean, professional, reassuring – that’s what converts.
- Context is king. A sports betting app used during a live match needs completely different UX than the same app used for pre-game analysis. We stopped designing “websites” and started designing “moments.”
The biggest evolution? Learning that our job isn’t to make gambling addictive, it’s to make good gambling experiences frictionless. There’s a massive difference.
Your site is the funnel, and its job is to drive a First-Time Deposit (FTD). Once you have that in mind, everything else takes shape around that singular goal.
SiGMA News: What’s one outdated UX practice you still see persisting in online casinos today?
Adir: Pop-up bonus offers, they drive me mental. You’ve got a new player who just signed up, they’re exploring your site, getting comfortable, building trust, and wham! – You assault them with a flashing modal demanding they claim a 200 percent bonus ‘RIGHT NOW!!!’ It’s like inviting someone to your house and immediately asking them to marry you.

I see major brands still doing this. The psychology is backwards. Players who are ready to deposit will find your bonus section. Players who aren’t will bounce when you pressure them. Good UX earns permission to make offers. It doesn’t demand immediate commitment.
SiGMA News: Having built platforms across casino, sports, bingo, lottery, and crypto, what UX elements consistently drive higher conversion rates in each vertical?
Adir: Each vertical has its own psychology:
- Casino players want immersion and escape. Conversion comes from making them forget they’re gambling online. Rich visuals, ambient sounds, seamless game-to-game transitions. The moment they remember they’re staring at a screen, you’ve lost them.
- Sports bettors are analytical and impatient. They want data, odds, and speed. Conversion happens through information density and quick betting flows. Three taps maximum from odds to bet slip.
- Bingo players are social and routine-driven. Chat features, regular schedules, and community elements drive loyalty. They’re not chasing big wins; they’re buying entertainment and friendship.
- Lottery players are dreamers. Beautiful visualization of potential wins, clear explanation of odds (counterintuitively, this builds trust), and simple purchase flows. Don’t overcomplicate the dream.
- Crypto players are tech-savvy and paranoid. Transparent provably fair mechanics, detailed transaction histories, and instant withdrawals. They understand the technology and want to see it working.
The common thread? Know why your players are there, then get out of their way.
SiGMA News: How do you balance regulatory compliance with clean, conversion-optimised design?
Adir: This is the art of constraint. Regulation forces us to be better designers, not worse ones. Take responsible gambling tools. The lazy approach is shoving everything into a footer link. The smart approach is making self-exclusion and deposit limits feel like premium features, not warnings.
I worked on a UK casino where we turned the reality check pop-ups into achievement notifications: “You’ve been playing like a pro for 60 minutes. Take a champion’s break?” Same compliance requirement, completely different psychological frame.
For Know Your Customer (KYC) verification, instead of treating it like a hurdle, we positioned it as VIP onboarding. “Complete your profile to unlock faster withdrawals and exclusive bonuses.” Same process, different story.
The secret is designing compliance as part of the experience, not an interruption to it.
SiGMA News: What are some of the most common UX mistakes, even from established brands, you continue to encounter?
Adir: Registration hell. Asking for 12 fields of information before someone’s even played a single game. I can open a bank account that is easier than signing up for some casinos.
Generic bonus offers. Showing the same 100 percent match bonus to a high roller who just withdrew €5,000 and a new player making their first €10 deposit. Personalisation isn’t rocket science.
Withdrawal friction. Making deposits instant but withdrawals take “3-5 business days for security.” It isn’t 2005. Players expect their money when they want it.
Mobile-first ignorance. Still seeing sites clearly designed on desktop then squashed to fit phones. Mobile isn’t a small desktop; it’s a completely different medium.
Ignoring loss psychology. When players lose, most sites go quiet or push more aggressive offers. Smart operators acknowledge the loss and offer genuine value – free spins, loyalty points, or just a “better luck next time” message that feels human.
Localisation & misconceptions
SiGMA News: How does localisation impact your design strategy? What changes when designing for regions like Brazil, India, or Africa compared to European markets?
Adir: Localisation goes way deeper than language translation. It’s about understanding cultural relationships with money, risk, and trust.
In Brazil, gambling is relatively new and social. Bright colors work. Community features are essential. Payment integration needs to be seamless because banking infrastructure varies widely. Brazilians want to feel they’re part of something bigger.
Whereas Africa is mobile-first by necessity, not choice. Data costs matter; every byte counts. Payment methods are diverse (mobile money is huge). Trust building takes longer because many players have been burned by fly-by-night operators.
Europe, on the other hand, is a mature market, and players are jaded. They’ve seen every bonus structure, every promotion. They value reliability over flash, transparency over hype.
The biggest mistake is assuming that what works in one market will work globally. A design that converts in Germany might completely flop in Nigeria, not because of different technical capabilities, but because of different cultural values around gambling, entertainment, and money.
SiGMA News: How do you navigate the design implications of highly regulated or fragmented markets, where onboarding processes and payment flows vary dramatically (e.g., Latin America vs. UKGC-regulated jurisdictions)?
Adir: We’ve learned to design for regulation as a feature, not a bug. Instead of treating compliance as constraints, we treat them as differentiation opportunities.
For highly regulated markets like the UK, we make the strictness feel premium. Detailed verification becomes “VIP account activation.” Extensive responsible gambling tools become “professional player controls.” Regulatory transparency becomes a trust signal.
For fragmented markets like Latin America, we build flexible frameworks. The same platform architecture supports Mexico’s sports betting rules, Brazil’s lottery regulations, and Colombia’s casino licensing – but each market gets a customised experience that feels native.
The design philosophy is regulatory camouflage – making compliance requirements feel like natural parts of the user experience rather than imposed barriers.
Payment flows are especially tricky. In some Latin American countries, bank transfers are preferred. In others, e-wallets dominate. In still others, cryptocurrency is the only viable option. We design payment pages that dynamically show only relevant methods based on user location and preferences.
The secret sauce is treating regulatory complexity as user experience challenge, not a technical problem. The operators who make compliance feel effortless win market share from competitors who make it feel bureaucratic.
SiGMA News: After 30 years in the industry, what are some of the recurring myths you still hear from new operators, particularly around design and player acquisition?
Adir: “Build it, and they will come.” No. Marketing is not optional. The most beautiful casino in the world will get zero players without a player acquisition strategy and without differentiating its brand. Another one is: “More games equals more players.” Wrong. Choice paralysis is real. I’ve seen casinos improve conversion rates by removing games, not adding them.
“Bigger bonuses win players.” Bigger bonuses attract bonus hunters who disappear after wagering requirements. Sustainable businesses are built on players who deposit regularly with modest bonuses.
“Mobile is just a small desktop.” This thinking kills conversions. Mobile gambling happens in different contexts with different motivations. Also, “AI will replace human creativity.” AI is a tool, like Photoshop or JavaScript. It makes creative people more powerful; it doesn’t make uncreative people creative.
The overarching myth is that success comes from copying successful competitors. The operators thriving today are the ones who zigged when everyone else zagged.
