To create a new version of their existing Sudoku game, called "Sudoku Real Money", which would allow users to earn real money by playing Sudoku and other games, with features such as virtual coins, gift cards, and withdrawal options via Visa or PayPal.

We aligned on the product goals, key features, and the direction for transforming the old Sudoku app into a reward-based experience.

Reviewed the existing version, uncovered usability issues, and identified friction points in both gameplay and earning mechanics.

Studied similar reward-driven products and user behavior patterns to clarify expectations around playing, earning, and withdrawing.

Mapped out clear user flows and created wireframes for all core parts of the product: gameplay, rewards, wallet, and cash-out.

Explored two visual directions, comparing clarity and usability, and selected the primary interface style together with the client.

Expanded the chosen direction into production-ready screens, ensuring consistency, readability, and a scalable component approach.

Built a reusable library of components, styles, icons, and interaction patterns to support smooth development and future growth.

Prepared store assets and marketing visuals, then delivered structured design files and documentation for an easy implementation phase.
