Neon 21 is a cyberpunk blackjack card game meets roguelike deck builder — play offline, no wifi needed. Build your deck, collect relics, and outplay AI bosses one hand at a time.

The house always wins. Prove it wrong.

━━ BLACKJACK MEETS ROGUELIKE STRATEGY ━━

Every combat is a strategic game of blackjack. Hit, stand, and outplay your opponent to deal damage. Bust and you take the hit. The closer you play to the edge, the harder you hit back.

Navigate a branching map through three acts — fight enemies, challenge elites, visit shops, rest at safe houses, encounter story events, and face bosses who rewrite the rules of the game.

━━ DECK BUILDING & RELIC SYNERGIES ━━

Collect powerful Relics that permanently alter your strategy:
• Neural Firewall — your first bust becomes an instant 21
• Volatile Core — bust damage redirects to your enemy
• Quantum Deck — see the next card before you draw
• Ghost Protocol — every push deals damage to the enemy
• Shadow Deck — 20% chance each hit draws two cards
• Thorn Wire — enemy takes damage whenever they draw

Deploy Ability Cards mid-combat for the tactical edge:
• Double Down — draw a card and double your damage
• Overdrive — push your bust threshold to 23
• Nullify — strip the highest card from the enemy's hand
• Data Spike — deal direct damage bypassing the round
• Card Scan — reveal and reorder the top 3 cards in your deck

━━ 30+ ENEMIES & 6 BOSSES ━━

Each boss rewrites the rules of blackjack:
• ARIA-7 — target is 22, bust at 23+
• The House — pushes deal damage; below 50% HP all damage doubles
• The Architect — your hand value is hidden for the first two rounds
• The Pit Boss — bust threshold rotates each round: 22 → 25 → 28 → 24
• Lady Luck — even rounds double all damage; odd rounds punish pushes
• The Algorithm — mirrors your hit count, drawing exactly as many cards as you

Elite enemies add their own twists — aces forced to 1, face cards worth 0, targets raised to 26, and more. Every fight demands a different strategy.
