UPGRADER: Upgrade Your Inventory!

UPGRADER: Upgrade Your Inventory! is a CS2 skin upgrade simulator where you gamble with your inventory, your luck, and your strategy. Three modes push your chances in different ways: Upgrade, Battle, and Contract. Over 1,000 items with real-world prices are available, including rarities like Glock-18 and Souvenir AWP Dragon Lore. Daily rewards bring knives, premium skins, and bonuses for completing tasks, while the leaderboard shows who really runs the skin economy.

How to play?

In Upgrade mode, pick a skin from your inventory, then choose a more expensive target skin. The bigger the price gap, the lower your success chance. Win, and you get the target skin; fail, and you get a consolation prize. In Battle mode, set the case price and number of participants. Everyone gets a random skin, and the player with the most expensive pull takes the entire pot. In Contract mode, trade 3 to 10 skins for a single, rarer item. Click with your mouse or tap the screen to pick skins, place bets, and launch upgrades, battles, and contracts. Sell skins for coins, then buy new ones in the store to grow and refresh your collection.
