Barcode Dungeon
Idle RPG from your barcodes
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Barcodes become heroes & gear. Scan daily to grow gear with Limit Break, or pull Mythic weapons in the Gacha. Same barcode = same hero, always. Fully offline. No ads.
[Every barcode around you becomes your adventure]
Scan QR codes or product barcodes — characters and gear are generated deterministically. Same code, same hero. Always.
■ Core Loop
· QR code → Companion (character)
· Product barcode → Gear (weapon or armor)
· Bring up to 3 companions on dungeon expeditions (progress even when the app is closed)
· Auto-battle earns Gold and EXP
■ Gacha & Limit Break (latest update)
· Mythic Gacha: spend Gold to pull T7–T10 legendary gear from world mythology
· Limit Break: re-scan the same barcode daily → spend Gold to raise star level (no cap)
· Full Scan Set (barcode weapon + armor): Attack +15%
· Full Mythic Set (gacha weapon + armor): Gold earned +20%
■ Determinism & Permanence
"Same barcode = same hero, forever." Even if the app is gone, your barcode brings back the same companion. Like a charm.
■ Deep Systems
· Prestige & Seals: reincarnate when your hero reaches the required level (scales up with each prestige) for permanent bonuses + stackable seals (Attack / Gold / Soul)
· Collection Multiplier: more gear and monsters discovered = stronger party
· ~3,000 monster species codex
· T1–T10 gear (history of technology → world mythology)
· Five Elements, race bonuses, prefix hack & slash
■ Three Principles (never change)
① Fully offline, zero servers
② Deterministic generation (same code = same result, always)
③ Zero ads
[Pro]
· Team 2 (two simultaneous expeditions)
· Companion renaming
· Camera scan for T10 gear

Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
The scanner has been recalibrated — more true forms are now revealed.
■ 6-Star Appearance Rate Greatly Increased
The chance of encountering a 6-Star companion via camera QR scan has been
significantly boosted. Legendary allies are now far easier to find.
■ "Awakening" System Unlocked
Spend 100 Souls to awaken a companion from their card.
An awakened companion gains power equivalent to 6-Star.
■ Special Reveal on First Launch
If any of your companions have been revealed as 6-Star by this update,
the scanner will announce their names when you open the app.
■ Training Ground Rebalanced
The stronger your party becomes, the easier the Training Ground gets.
Growth now feels more rewarding.
