Blackwood Manor has been waiting for you. Rayvin is a gothic tarot match-3 built around a single, satisfying gesture: you don't swap tiles — you draw. Trace one continuous line through three or more matching arcana in any direction, including diagonals, and watch the cards dissolve into mist. FIFTY-FIVE LEVELS, FIVE CHAPTERS An occult mystery in five acts, told across fifty-five hand-tuned levels. Earn your way deeper into the manor one chapter at a time, breaking the wax seals as you go. LIVING PORTRAITS Five antagonists guard the manor's secrets. Tap a character's medallion and their oil portrait unrolls — and speaks to you. Lady Evelyn Blackwood. Malakar. Mademoiselle Vespera. Father Lucien. Arch-Sorceress Morvath. HAZARDS WORTH THE CANDLE Shatter iron chains. Cleanse shadow corruption before it spreads. Break stone gargoyles that refuse to be matched. Every hazard you clear pays you in both score and progress. RELICS AND RITUALS Spend Arcana Essence in the Reliquary on the Bone Hammer, the Phantasmal Scythe, and the Tarot Shuffle. Draw from the daily altar for a card and a reward, and keep your streak alive. NEVER STUCK If a board ever runs out of legal moves, the arcana rearrange themselves — free, costing you neither a move nor a relic, with everything you've already cleared left intact. PAY ONCE. THAT'S ALL. No advertisements. No in-app purchases. No energy timers. No accounts to create, no email to hand over, and nothing asked of you a second time. GENUINELY PRIVATE Rayvin collects nothing. There is no analytics, no tracking, no third-party code, and no server — the app makes no network requests at all. Your progress lives on your iPhone and nowhere else. It plays perfectly on Airplane Mode. Light a candle. The cards are waiting.
