About this game

Welcome to Vault Run, a high-risk, high-reward casual strategy game where every decision could multiply your haul—or erase it in an instant.

You play as a master infiltrator breaking through layered vaults. Each lock presents a simple but tense choice: HIGH or LOW. Predict correctly to open the vault and increase your loot. Make the wrong call (or run out of time) and the Alarm Bar rises fast. When the alarm reaches full, the run ends and all unsecured loot is lost.

Core Features

HIGH / LOW Lock Decisions

Each vault shows a base value.

Choose whether the real code is higher or lower.

Correct choices open the lock and boost your rewards.

Extract Anytime

You can extract at any moment to secure what you’ve earned.

Staying longer increases rewards—but also increases risk.

Alarm System

Wrong choices and timeouts raise the Alarm Bar.

Let it fill up and your unsecured loot is gone.

Manage your risk, control your pace, and know when to leave.

Crew & Tools

Build a crew that provides passive boosts like reduced alarm gain, extra time, and better reward scaling.

Equip tools with powerful effects: reduce alarm pressure, skip dangerous locks, reveal better odds, or provide emergency protection.

Upgrade your loadout to reach deeper vault tiers.

Progression & Vault Tiers

Deeper tiers introduce tougher patterns, higher pressure, and bigger payoffs.
Earn rewards after every run to improve your crew, tools, and access.
