'Champions League Album' - Football Card Album In Mini-app

Objective

Liga Stavok, Russia's leading sports betting platform, aimed to capitalize on the UEFA Champions League season to build sustained user engagement through collectible mechanics. The campaign was designed to motivate daily platform interaction, prime users for betting activity, and drive participation in a high-value sweepstakes tied to the tournament's flagship event.

Solution

Agency Trend Surfers built an interactive Telegram mini-app (2025) where users completed daily quests (word-of-the-day challenges, missions, daily tasks) to earn card packs. These packs populated a virtual album featuring player cards from Champions League club rosters, with a fill-progress indicator and notifications for rare cards. A leaderboard ranked participants by collection progress, with raffle mechanics awarding prizes to consistent players: a trip to the Champions League final in Budapest, freebets from 20,000 ₽, an iPhone 17 Pro, and a PS5. The experience was fully responsive for mobile devices, emphasizing accessibility and quick daily play sessions. Liga Stavok later reused the same collectible-album format for the 2026 World Cup, showing the mechanic's continued rollout beyond the original campaign.
