Dolphin — Review and User Feedback on the CS2, Dota 2, and Rust Case Opening Site (2026)

Dolphin is an online platform for opening cases in CS2, Dota 2, and Rust, where users can obtain skins, participate in raffles, and use promo codes for bonuses. The site appeared relatively recently but has already attracted attention due to its simple interface, a wide selection of cases, and additional game modes.

Interface and Navigation

The site features a dark-blue color scheme with smooth transitions and minimal animations. The interface is intuitive: even a new user can easily navigate the case section, promotions, and profile settings. The homepage contains key sections such as “Vip-Club”, “Raffles”, “Partnerships”, as well as a block with current events and popular cases.

At the top, there is a Live feed showing current user wins, while the left side hosts the game menu. The footer contains links to social media, contact information, and legal details. In the user profile, you can view activity statistics, deposit and withdrawal history, current level, and inventory. The interface is available in Russian only.

Registration on Dolphin

Registration takes less than a minute. You can log in via Steam, VK, or Telegram, confirming that you are 18+ and agree to the platform’s terms.

No identity verification is required, so you can start playing immediately after registration and depositing funds.

Deposits and Withdrawals

Dolphin supports a wide range of deposit and withdrawal options, including bank cards, payment systems, and cryptocurrency.

Available deposit methods:

• Bank cards: VISA, MasterCard, MIR

• Payment systems: SBP, FreeKassa, FK Wallet, YooMoney

• Skins: Skinsback, Skinify

• Cryptocurrencies: USDT, TRON, BTC, BNB, ETH, LTC, TON

• Gift cards: Kinguin

Withdrawals can be made to a Steam balance, as skins, or via cryptocurrency (USDT TRC-20). Users report that transactions are processed quickly, and the status of withdrawals is displayed in the profile.

Case Opening

The main feature of the platform is cases, created exclusively by the site team. These cases are unique and not repeated on other platforms.
Cases are divided by game (CS2, Dota 2, Rust), and filters allow sorting by name, category, or price.

Upgrade Mode

The upgrade mode allows players to improve an existing skin without opening a new case. Users select an item, indicate the target skin, and start the process. The probability of success depends on item value — the higher the risk, the higher the potential reward.

Contracts

In the contracts section, users can combine three to ten items into one. The final drop is determined randomly, adding an element of unpredictability.

Case Battle

The Case Battle mode is a duel between multiple users, where everyone opens identical cases. The player who receives the most valuable drop wins the entire reward. This mode appeals to those who prefer a competitive format.

Current promo codes:

• Freeru — +15% to the deposit (min. 40 ₽)

• cfg — opens a free “Antarctica” case with a 50% deposit playthrough requirement

Additional rewards:

• 10 coins for subscribing to Telegram and VK

• 70 coins for completing a Steam profile (prefix + avatar)

• Bonus Wheel available every 48 hours, offering cases, skins, or promo codes

The site also hosts regular raffles for users who have deposited funds in the last 24 hours. Each event specifies minimum participation amounts and prize pools.

Vip-Club Loyalty Program

The Vip-Club system is designed for regular users. Every spent unit of currency earns XP, which increases the user’s status.

There are five levels: Bronze, Silver, Gold, Diamond, and Sapphire. Higher levels offer more benefits: cashback, free cases, exclusive promo codes, and priority support.

Skin Marketplace

In 2026, Dolphin introduced a full skin marketplace, where users can buy skins for CS2, Dota 2, and Rust using their platform balance. Purchases are instant, and items appear automatically in the inventory. This option is convenient for users who prefer direct exchanges without intermediaries.

Customer Support

Support is available via Live Chat at the bottom-left corner of the site. Responses are provided by real moderators, not bots, usually within minutes.

Users can also contact the administration via official social media channels listed in the footer. Support is available daily and assists with deposits, withdrawals, bonuses, and technical issues.

Conclusion: Is Dolphin Worth Playing?

Dolphin is a modern platform for opening cases in CS2, Dota 2, and Rust, offering multiple game modes, bonuses, and promo codes for free cases.

The site stands out with intuitive navigation, a variety of modes (upgrade, contracts, case battles), and a loyalty system via Vip-Club. However, it remains an entertainment platform where winnings are not guaranteed, so participation should be measured and responsible.
