The Design Challenge

Owning a live social casino title solo meant every design decision, from slot themes to event timing, had a direct and measurable impact on revenue. The challenge was balancing short-term monetisation goals with long-term player retention, ensuring events felt rewarding rather than extractive. This pushed me to develop a strong data literacy alongside my design instincts, reviewing KPIs every quarter and iterating rapidly based on what the numbers were telling me.
