Collect, trade, and battle with virtual tennis cards



Tennis Relics is a digital sports card platform centered on tennis players, legends, and prospects. It addresses the lack of dedicated virtual card collecting ecosystems for tennis enthusiasts by bringing card collecting, trading, and mini-games into a single web application. Users can collect player cards across different rarities, track their collection value in a personal binder, and earn in-game coins through daily interactions.
The platform separates itself from static digital binders by combining traditional collecting mechanisms with interactive mini-games and secure exchange systems. Users can use their digital cards directly in turn-based matches against computer rivals or other players, creating an active reason to build a balanced squad alongside casual collecting.
All trading and marketplace mechanics use an internal virtual coin economy. Digital ownership is managed through database-verified transfers, ensuring exchanges occur simultaneously and preventing unfulfilled trades.
Tennis Relics is designed for tennis enthusiasts and digital card collectors looking for casual gameplay and item management.
A tennis fan can sign in each morning to answer the daily court trivia question, maintain a 7-day login streak, and collect coins to spend on higher-tier Grand Slam packs.
Two friends can connect online using a quick 6-character room code to enter a head-to-head turn-based tennis duel, picking shot types like Safe rally, Power shot, and Drop shot to reach three points.
A trading card hobbyist can monitor the marketplace and auction listings to hunt down missing rare cards, bidding surplus coins to complete their team binder.
Tennis Relics is completely free to play. There are no paid subscription tiers, real-money purchases, or lifetime deals mentioned. All card packs, marketplace purchases, and auction bids use in-game virtual coins that players accumulate through login streaks, quizzes, matches, and challenges.
Is Tennis Relics free to play?
Yes. The platform operates on an internal virtual coin system that you earn through daily logins, quizzes, challenges, and match victories without real-money purchases.
How do Court Battles work?
Court Battles are turn-based matches where you choose a card from your binder and select shot types like Safe rally, Power shot, or Drop shot. The first player to reach 3 points wins the match and earns coins.
How does safe trading work?
Trades are protected by Supabase ownership checks. Cards only transfer once the recipient confirms the trade, ensuring both cards move at the exact same time or the exchange is cancelled.
Can I play against other people online?
Yes. You can host an online match, receive a 6-character match code, and share it with another player to compete directly over the web.
