CS2BonusCode Testing Methodology
CS2BonusCode.com verifies promo codes through a fresh-account testing process. Codes that fail testing are removed. This site earns affiliate commissions from the platforms listed — see our affiliate disclosure.
The 8-Step Verification Process
- Create a new Steam account. A new Steam account is created with Steam Guard Mobile Authenticator enabled. Using a fresh account eliminates any prior account state that could affect bonus eligibility.
- Register on the target site via Steam login. The new Steam account is used to register on the case-opening site. We confirm the account has no prior history with the platform.
- Enter the promo code in the designated field. The code is entered exactly as listed on CS2BonusCode.com — including exact capitalization. We verify the code is accepted without error.
- Deposit the minimum amount. A deposit is made using the site's minimum amount ($1.00 on most sites, $2.00 on Key-Drop). We use a consistent payment method across tests where possible.
- Verify the bonus balance matches the advertised percentage. After the deposit clears, we check the account balance against the expected value. A 20% bonus on a $10 deposit should produce exactly $12.00 in site balance.
- Open one case and request a withdrawal. To test the full flow, we open one $0.10 case and request the skin be withdrawn to the Steam account via Trade Offer.
- Measure withdrawal time. We record the time from clicking "Withdraw" to receiving the Steam Trade Offer notification. Results are updated in the comparison table on the home page.
- Record and publish results. Results are saved with timestamps. If a code fails (not accepted, wrong bonus amount, withdrawal issue), the code is flagged, verified on a second account, and removed if failure is confirmed. Updates post within 24 hours.

Ranking Criteria

- Withdrawal speed: Measured in seconds or minutes
- Trust signals: Years of operation, registered users, corporate registration country
We earn affiliate commissions from the platforms listed. This does not change the promo codes or bonuses available to you — compensation comes from the platform, not from users.
What We Do Not Do
- We do not copy codes from aggregator sites without testing them independently.
- We do not estimate or guess bonus percentages — all values are confirmed by deposit.
- We do not list sites we cannot test on a real account with real deposits.
