    Our favorite features

    Leaderboard & competition mode

    A ranking system lets players measure themselves against one another and track their progress. This competitive mode reinforces engagement and creates community dynamics around the game.

    AI Battle mode

    A solo mode lets users play against an AI with different difficulty levels. This feature offers an ideal environment to practise and progress at one's own pace.

    Conception

    Reinventing a millennia-old game for mobile starts by understanding what makes people come back to it. The design phase laid down two pillars: a game-AI engine able to adapt to the player's level, and a competitive system with real-time ranking to stimulate progression and loyalty.

    The user flows were designed to minimise the time between opening the app and starting a game.

    Design

    Deep burgundy, leather textures, gold serif typography — the visual identity asserts a premium heritage while remaining perfectly legible on small screens. The design system was extended to three distinct game modes (solo, multiplayer, competition) with a strong consistency that reinforces a sense of belonging to a community of serious players.

    Development

    Zetos developed the AI game engine, the matchmaking system and the dynamic leaderboard on an architecture able to absorb simultaneous sessions in real time.

    Technical stability was as much a priority as the experience itself — one bug in a competitive match means one lost user.

    Technologies used

    The Doubles mobile app runs on a robust architecture using Kotlin, Swift and React on the frontend, paired with a Java + MySQL backend, all optimised with Redis and hosted on AWS.
