Barcode Dungeon
Idle RPG from your barcodes
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Barcodes become heroes & gear. Defenders protect, Healers recover, Attackers blitz. 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

■ Game Balance Adjustments
Dungeon difficulty, EXP gain, and Gold rewards have been rebalanced

Defenders help your party reach deeper floors safely. Healers reduce
the chance of wipeout. Rarity, Weapon Tier, and roles now visibly
affect expedition outcomes.

Standby members are now grouped by Rarity; weapons are grouped
by Tier — easier to manage at a glance.
