Overview
A PvP game where players predict the BTC price in short head-to-head rounds — designed as a game first and a betting app second.
The task
Betting on crypto prices usually means a chart and two buttons. Predictrum wanted it to feel like a game: real opponents, short rounds and cards that change the outcome — while staying clear about where the money goes. Even the landing page sells the arena, not the odds: characters and cards first, fees and fairness after.
Lobby and duel
Everything starts in the lobby: pick a game mode, a bet room and hit Play. From there it's a duel — two players, 10 rounds, one question each round: will BTC go up or down? Before every round you play a card, and HP bars show who's ahead. I designed the whole loop: matchmaking, the VS screen, card choice, the 10-second round and every ending — win, draw and loss.
On mobile and solo
Most players will be on their phones, so every duel screen was designed for mobile first, then scaled up to tablet and desktop. For players who want to warm up, there's a classic solo mode against the market — the same chart and the same 10-second rounds, just without an opponent.
Around the game
A wallet with USDT deposits, withdrawals and full transaction history, including empty and error states. Referrals, profile and game history keep players coming back, and six short cards teach the rules before the first match. The card set holds the game together: 18 cards across attack, defense and combo, each with its own cost and effect.
