Fivefold Master Duel (Prototype)

Note: This is currently an early prototype version. We have a lot of exciting updates and improvements planned for the future!

FIVEFOLD: Master Duel

FIVEFOLD: Master Duel is a strategic, turn-based card battler set in a dark fantasy world. Use standard playing cards combined with an arsenal of powerful magical Function cards to outsmart your AI opponent.

Features:

• 🃏 Unique Poker-Based Combat: Build the strongest 5-card combo (Pair, Flush, Full House, etc.) to deal damage.
• 🌑 DARK GAME Expansion (Now Live!): A massive alternate gameplay system featuring Jokers, Dark Rare Function Cards, and entirely new, rule-breaking "Epic Combos" that go far beyond traditional Poker formats (summon the Demon King, Legendary Hero, or Avatar Reborn for devastating One-Turn-Kills!).
• 💀 Roguelike Survival Mode: Descend into the endless Abyss! Face escalating waves of enemies, draft persistent decks, earn powerful relics/buffs, and sacrifice unused cards at the Divine Altar to survive the grueling Superior Hell difficulty.
• 🛠️ Custom Deck Builder (Mystic Arsenal): Tailor your strategy before the duel. Choose exactly 8 Function Cards (or 10 in Dark Game) from a pool of over 50 unique Common, Rare, and Dark Rare spells to create your ultimate deck archetype.
• ✨ Spells, Traps & Clash Phase: Play spells directly from your hand, or Set structure and trap cards (like Shield, Combo Breaker, or Fortress) face-down to counter your opponent's attacks during the tense interactive Clash Phase.
• 👑 Royal Unlocks & Overdrive: Face cards (J, Q, K) have unique scaling mechanics based on the board, hand, and graveyard. Unlock the Ace to activate Overdrive, doubling your damage cap and unleashing ultimate cinematic attacks!
• 👿 4+ AI Difficulties: From a casual "Easy" mode to the ruthless, cheating "HELL" mode (and the hidden "Superior Hell" in deep Survival runs).
• 🏆 Rank System: Earn multiplier points based on your performance, win streaks, and difficulty to climb the ranks from Peasant to Celestial (or even the hidden God rank!).
• 🎓 Interactive Tutorial Hub: Master the Abyss with a fully playable 7-lesson tutorial, including a Sandbox "Trial Chamber" to test your craziest combos.

How to Play:

• 🎯 Objective: Deplete the AI opponent's HP to 0 before they defeat you.
• 🃏 The Basics: Summon cards from your Hand to the Combat Zone. Once you have exactly 5 normal cards (or a Mythical Stand) on the field, click "Declare Combat" (or End Turn) to battle.
• ⚔️ Combat Power & Clash: Your damage is based on classic Poker combinations. Before damage is calculated, the Clash Phase begins, allowing players to flip face-down Traps to defend or disrupt the enemy.
• ✨ Cast & Set: Play Function Cards (the glowing cards) directly from your hand to cast spells (draw cards, steal from the grave, buff stats). Some cards must be Set face-down to protect you during the Clash Phase.
• 🔥 Triple Suit & Four-of-a-Kind: Hold 3 cards of the same suit in your hand to unlock a devastating special attack (reduce enemy stats, steal cards, or destroy enemy combos). Hold 4 cards of the same rank to sacrifice them and revive any card from the graveyards!
• 🔄 Adapt: Not happy with your field? You can replace up to 2 cards on the board per turn to perfect your combo!
• 📖 Tip: Use the in-game "Game Guide" or "Combo Collection" to check exact damage formulas, Royal card unlock conditions, and Epic Combo recipes!

🚀 Future Updates (Roadmap):

• PvP Mode: Battle against other players online in real-time matchmaking.
• Story Mode / Lore Campaign: Dive deep into the dark fantasy lore behind the Avatars, Archons, and the Demon King.
• More Roguelike Events: Additional random encounters, elite bosses, and branching paths for Survival Mode.
