csmafia 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, with the highest total value taking 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 set aside for case battles. Steam trade withdrawal is in development pending licensing. Balance withdrawal is crypto-only.

csmafia 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.

Our goal is for the Service to stay a fun, light experience. This page explains how to keep it that way and where to find help if play stops being fun.

1. Play for entertainment

csmafia is meant to be fun. The coins and items on the Service are for entertainment and have no real-world monetary value. You should only ever spend what you are comfortable using for entertainment, and never treat the Service as a way to make money or to recover money.

2. Adults only

The Service is strictly for persons aged 18 or older (or the age of majority where you live, if higher). We take age limits seriously and will close any account we believe belongs to a minor.

3. Stay in control

A few simple habits help keep things fun:

  • decide in advance how much time and money you want to spend, and stick to it;
  • treat any spend as the cost of entertainment, not an investment;
  • never chase a result, and don't spend to win something back;
  • take regular breaks, and don't play when stressed, upset, or under the influence.

4. Self-exclusion, limits, and cool-off

If you want help staying in control, contact us at [email protected] and we can apply a cool-off period, set limits, or self-exclude your account for a fixed period or permanently. While a self-exclusion is in force we will close access to your account and will not reverse it before the period ends.

5. Signs it may be becoming a problem

It may be time to stop and seek support if you:

  • spend more time or money than you intended;
  • play to escape problems or feelings of stress or low mood;
  • feel anxious, guilty, or irritable about your play;
  • borrow money, or neglect work, study, or relationships, to keep playing.

6. Where to get help

If you or someone you know needs support, free and confidential help is available, including:

  • Gambling Therapy — international support and live help: gamblingtherapy.org
  • GamCare — advice and a free helpline: gamcare.org.uk
  • BeGambleAware — information and support: begambleaware.org

Support services are also available in many countries through local health services and charities.

7. Protecting minors

If a minor has access to your devices, please use parental controls and keep your sign-in details private. Tools such as family filters can help block access to age-restricted content.
