## What is HydroValve?

Route water from SUPPLY to every DRAIN — through pipes that stay EMPTY while you build. There's no preview and no undo once the valve opens: trace the flow in your head, commit, and watch your route hold… or leak.

Every leak drains the same shared tank. At 0%, the run is over.

SURVIVAL — Permadeath against a build clock. At zero, the valve opens itself. Learnable, fixed levels: every scene is the same every run — master them.
CHALLENGE — The plumbing is already installed… and sabotaged. Find and fix every fault before you commit.
CAMPAIGN — Descend through six facilities. Saves after every level, but once open, the valve NEVER shuts.

LIVING MACHINERY — Treatment units scrub fouled water. Gate valves ship shut. Welded faults resist repair. Cracked floors bleed your reserve. Deep levels stack everything at once.
KEEP IT PURE — Water fouls as it travels. Run it too far unwashed and it clogs — then bursts. Route through purifiers, or drop portable filters where you need them.
WORLD RECORDS — Post your best runs to a live worldwide leaderboard. Three letters, your level, your time. No account, no sign-up.
PERFECT ROUTING — Every clear is graded against par. Zero waste earns three stars.

Six facilities. Twenty achievements. One shared tank.
Hold the pressure.

## Version history (last 3 releases)

### 1.2 — 2026-09-19

Tuning update.
- Ad placements refined: an ad may show when you return to the main screen after a run, and after every third level cleared in a row. Never back-to-back, and Remove Ads turns them all off.
- Fixed a records-screen request bug.

### 1.1 (3) — 2026-09-17

Player accounts have arrived. Sign in with Apple or Google — or clock in as a guest — and your world records follow you between devices. A new PROFILE page shows your personal bests and lifetime service record, and you can delete your account any time.

Two new shifts: DAILY SHIFT gives the whole world the same board, one attempt a day. BLIND SHIFT shows you the plumbing for ten seconds, then the lights go out. Six new achievements to match.

Leaderboards now keep one best entry per player. Optional rewarded boosts: Overtime, Fault Scan and Tank Patch. Plus fixes and polish.

### 1.0 — 2026-09-16
