🌊 Dive cycle
Your sub auto-dives, collects loot, and surfaces to sell. You don't pilot it — you upgrade it.
⚡ Boost
Tap the boost button for +200% speed and pickup rate. Tap again while active to add +1 second, up to a 10s cap. Cooldown starts after it ends.
🔧 Outfitting
Spend cash to upgrade Hull, Thrusters, Cargo, Sonar, and Appraiser. Levels reset on Promotion.
🎒 On Deck & encounters
Items collected this dive show in the Sub tab. Every encounter — bonuses (Lucky Current, Mermaid's Kiss, Treasure Map) and the Shark Attack hazard — comes from the Salvage Slot.
🎰 Salvage Slot
The slot in the corner auto-pulls every 15s. Triple matches: 🌊 Lucky Current (2× cargo, 15s), 🧜 Mermaid's Kiss (2× value, 15s), 🗺 Treasure Map (legendary picks at 10× value, 30s), 🌟 Jackpot (all three, 30s). 🦈 triple = Shark Attack (no loot for 10s).
📦 Treasure chests
Bronze/Silver/Gold chests spawn occasionally. Tap to add to your tray (next to the cash). Tap a tray chest to open — multi-item rolls biased toward higher rarity.
⚓ Promotion & pearls
Hit a tier's level threshold (every 10 levels) to promote. Promotion banks pearls based on your run's lifetime earnings and resets level/cash/upgrades. Each pearl is +0.5% loot value, forever.
🏆 Honors
Achievements unlock as you play but aren't free — open the Honors tab and tap each one to claim its cash reward.
