VOX Casino: How a Full Platform Migration Unlocked +36% GGR in 12 Months

VOX Casino had outgrown its own infrastructure. The in-house legacy platform had no native A/B testing, which meant most product decisions relied on assumption rather than evidence. The retention and bonus toolkit was limited: few mechanics, minimal personalization, no segment-level control. Key game providers were absent from the catalog, narrowing the content offering in competitive European GEOs. The team had strong product instincts but the platform beneath them had become a constraint. Iteration took longer than needed. Experimentation was limited. Growth was harder to sustain.

Kanggiten delivered a full platform migration on microservice architecture, eliminating monolithic release cycles and isolating failures at the service level. The project went live 2.5 months after contract signing. 

VOX gained access to Kanggiten’s A/B testing framework, a flexible bonus engine, customizable cashier settings, personalized game recommendations, and a deep integration layer for new providers. 

Built-in DDoS protection and horizontal scaling keep the platform stable under traffic growth across European markets. What VOX got was not a one-time upgrade. It was infrastructure for continuous product iteration, with every tool needed to test, measure, and scale.

Over 10 tests rebuilt the signup flow from scratch. The team reduced form steps, added re-engagement triggers for incomplete signups, introduced a new registration entry point, and integrated Google authentication with a custom button design. Each change was isolated and measured against Click-to-Registration rate and time to complete. 

• Click-to-Registration: up to +16%
• Avg. registration time: -20%

Kanggiten built a custom onboarding configurator at VOX’s request. The team used it to test urgency mechanics, including a limited welcome offer with a countdown timer, and launched a dedicated welcome page. Both experiments targeted the gap between signup and first deposit, with secondary focus on conversion into repeat deposits.

• FTD conversion: up to +17%
• Time to first deposit: -25%
• 1st-to-2nd deposit conversion: up to +10%

15+ experiments covered the full deposit experience. VOX gained control over cashier limits, preset amounts, price points, and payment method ordering. The team redesigned the cashier layout, tested upsell placement, optimized price points across methods, and added a 1-click deposit widget for returning players. None of the upsell mechanics had a negative impact on cashout behavior.

• ARPPU: up to +21%
• Cashier-to-deposit conversion: +8%
• Repeat Rate: up to +12%

Kanggiten enabled segment-level bonus configuration and built new mechanics on request. VOX launched individualized bonus offers, reconfigured cashback rules, introduced a VIP Club with dedicated retention flows, and rolled out a referral program. Referred users consistently outperformed the baseline segment across all core metrics. Cashback costs dropped without affecting retention.

• InOut per participant: up to +48%
• VIP segment retention: +16%
• Monthly cashback costs: -21%
• Referral FTD conversion: 6x baseline

Tests targeted player activity, engagement loops, and support load. The team redesigned the bonus page and bonus cards, added FAQ sections under each promotion, built an in-app store and lootbox mechanic, surfaced free spins directly in user profiles, and introduced a low-balance deposit trigger. Several of these changes cut support volume while simultaneously improving retention.

• Retention: up to +16% at d14
• Repeat Rate: up to +14%
• Support requests: down up to -58% on specific topics

Kanggiten enabled personalized game recommendations and in-game navigation menus, giving players faster access to relevant content. VOX also integrated 26 new providers, adding titles popular across their target European GEOs. The result was longer sessions, more spins per player, and higher per-user revenue.

• Avg. session duration: up to +14%
• GGR per user: up to +19%
• Spins per user: +23%
