Cs Mafia is a CS2 case-opening platform built around provably fair mechanics. Every case opening, battle round, and upgrade roll is generated from a publicly committed server seed, a player-controlled client seed, and a monotonically incrementing nonce, outcomes can be independently verified after the fact.

Open cases to pull skins across the rarity spectrum. Run case battles with up to four players and fifty rounds, the highest total value takes everything. Upgrade skins by staking your inventory toward a higher-value target, odds and house edge are shown before every roll.

Skins can be sold back for instant balance, used as upgrade stakes, or withdrawn to your own Steam account by trade. Balance is spent on the site and is not paid out as cash.

Cs Mafia is for entertainment. 18+ only, or the legal age in your jurisdiction if higher. Coins and items are part of the experience and have no real-world monetary value.
