## What is RustGrade?

RustGrade is a crate opening and skin upgrade simulator inspired by survival games. Open crates, build your inventory and push your items higher on the upgrade wheel. Everything runs on in-game balance: no real money, no in-app purchases.

CRATES

Twenty crates, from a cheap barrel to the heli crate: elite crate, locked crate, airdrop, Bradley crate. Contents and drop chances are shown before you open. Open one at a time or up to ten at once, and get a free crate for watching a short video.

UPGRADE

Pick one or several items, choose a more valuable target and spin the wheel. The chance is shown in the center of the wheel before the spin and stays the same while the arrow flies. Get lucky and the target is yours; if not, you still get a consolation prize.

• One-tap targets: x2, x4, x8 buttons and your own chance presets
• Not enough chance? Boost it with your in-game balance
• Fast spin when you are short on time

SHOP AND INVENTORY

• 5,000+ skins: weapons, armor, clothing, doors and boxes for your base
• Filters by price, category and rarity, search by name
• Sell in one tap, item by item or the whole inventory

PROFILE

Upgrade stats: best streak, best drop, average chance and full history. Sound and vibration are adjustable.

No sign-in required: everything is available right away and progress is stored on your device. Sign in with Apple or Google to keep it in the cloud and move it to another phone. You can delete your account right in the app.
