From Idea to Code

The mechanics of the promotion were as follows:

1. Buy the product in special promotional packaging.
2. Register your receipt on the website.
3. Play the games.
4. Get points.
5. Participate in the prize draw.

Six different game mechanics were added to the website:

• Battleship — for strategists.
• Fruit Ninja — for virtual blade masters.
• Matchstick puzzles — for those who like to train their brain.
• Quiz — for the erudite and knowledgeable.
• Hidden object search — for the most attentive.
• Detective puzzles — for those seeking the truth in the details.

Each game was developed with UX in mind: timers, interactive elements, and instant feedback. 

How Did It Work Technically?

The website was implemented using the stack: HTML/JS/CSS, Java, Vaadin. 

Automatic receipt moderation was done via the Federal Tax Service (FTS) API — the system automatically checked uniqueness, purchase date, presence of the promotional product, and Taxpayer Identification Number (INN). If something went wrong, the user received a clear notification without unnecessary bureaucracy.

The admin panel allowed managing content, monitoring receipts, and tracking each new participant. And there were quite a few participants:

• 71,000+ website visits.
• 7,000+ registered users.
• 10,000+ uploaded receipts.
• And, attention: 13,000+ units of product sold.

The Result?

The project was a success. Sales increased, and users were satisfied)
