## What is Trench Tycoon?

Somewhere below the last line on the chart, there is still ore. Trench Tycoon is a deep-sea mining tycoon about going down there to get it: one lantern, one rig, one octopus foreman in a brass diving helmet — and a city on the seafloor that grows deeper and stranger the longer you play.

LIGHT THE ABYSS
Every machine you buy appears in the scene and gets to work: drills bite into the seabed, drones and rovers ferry the ore, ships haul it to the surface, refineries turn it into something worth the trip. Grow a fleet and it changes shape — bigger hulls, brighter lamps, new silhouettes — until the black water is full of warm little lights. Whales, giant squid and stranger things drift past in the dark; tap them for a bonus.

FIND THE BOTTLENECK
Your operation is a real logistics chain: extract, collect, transport, refine. Income is whatever the slowest stage can move, and the amber line key on the work drawer shows you where that is. Fixing the bottleneck beats buying the most expensive thing.

DEEPER, STRANGER
When the company has earned enough, move the whole operation to a new trench — nothing resets. The water gets darker, the scenery shifts with it, and each trench opens a new form for one of your lines: drills become vent harvesters, drones become rover fleets, and a refit in the shipyard turns the whole line over. A research lab full of illustrated blueprints grows with you, and some of it only opens further down. Nine trenches, down to Challenger Deep.

THE FOREMAN'S JOB BOARD
When you want something for your hands, the octopus foreman keeps a board of quick jobs: ping the dark with sonar, match ore samples, stop the drill dead centre, follow the gold nugget through a shell shuffle and repeat the control panel's lamp sequence. Each game takes under a minute and pays out in credits — pure skill.

STILL WORKING WHILE YOU'RE AWAY
The rigs keep mining for hours after you close the app, up to a cap that research and the Pro Pass can raise. Come back, collect, upgrade, leave.

ALSO DOWN THERE
• Two codices to fill: the visitors of each depth, and the rare ores your foreman turns up when you tap the rig.
• A 30-day attendance calendar and a board of achievements.
• Everything on screen is drawn in code — no stock art — in English and Korean.

FAIR BY DESIGN
• Free to play with no forced ads: rewarded ads play only when you tap a reward button, and everything in the game is reachable without them.
• Optional purchases: the Pro Pass (every ad reward instantly, a longer offline haul, Pro research, the full codex and rig skins), a 24-hour time warp and a permanent ×2. No loot boxes, no energy system.
• No account and no server. Progress is saved on this device only; non-consumable purchases restore through your Apple Account.

From one lantern to a city on the seafloor. That's the plan, Boss.

## Version history (last 2 releases)

### 1.2.0 — 2026-10-16

Every line now grows a fourth form deep in the trenches: the Mantle Crystal Miner, the Hive Carrier, the Hadal Elevator and, at Challenger Deep, the Pure Gold Distillery. Each one opens for a refit once the form before it reaches Mk V. Challenger Deep also reveals the extract line's fifth form, the Ancient Rock Breaker; its refit opens once two hundred Mantle Crystal Miners are on the job. Job board mastery: three perfect boards raise a game's mastery, and every level pays more. Shell shuffle adds a shell every round and swaps two pairs at once from four shells, now at a calmer pace; a perfect sample match allows five misses. Big numbers read Qa, Qi, Sx and so on after T. When a refit opens, your mechanic saves for it on every line until you refit.

### 1.1.0 — 2026-10-14

No release notes.
