Games You Can Play Using Your CobaltLab Bonus

CobaltLab features a diverse set of games where you can use your bonus funds, rakeback, and Sulfur. Playing these games provides an interactive and entertaining experience for users. Most games offer a competitive RTP and are designed to appeal to both casual players and high-stake gamblers.

Here’s a breakdown of the top games:

Mines (RTP 95%)

One of the most popular games on the site. You choose a grid (5×5 to 8×8) and try to click on safe tiles while avoiding hidden mines.

• Each safe cell revealed increases your multiplier.
• Cash out at any time or risk it all to keep going.
• Max bet: 150 Sulfur | Max win: 10,000
• Available in both manual and auto mode for strategic or fast-paced gameplay.

Mines Battle (RTP 95%)

A multiplayer twist on the classic Mines format. You play against another user on a 5×5 grid.

• Normal Battle: Take turns selecting cells; highest total value wins.
• Cursed Battle: First player to hit a mine loses instantly.
• Max win: 1,500 – higher pots with more players in the room.

Crates & Case Battles (RTP 92%)

Crates are the backbone of Rust skin gambling, and CobaltLab does it right.

• Crates: Choose from hundreds of themed cases. Open up to 4 crates in one round. Each drop is verifiably fair.
• Case Battles: Compete in real-time with others. Whoever gets the highest value from their crates wins the battle. Some battles offer random-chance outcomes weighted by total drop values.

Before depositing or withdrawing skins, always check your inventory status and any trade restrictions to avoid errors and ensure successful transactions.

Provably Fair Gaming: How CobaltLab Ensures Transparency

CobaltLab runs on a Provably Fair infrastructure, giving players full visibility into how results are calculated – ensuring no manipulation is possible. The platform also safeguards user data through security measures like SSL encryption and provably fair systems, emphasizing trust and data protection. Each game outcome can be independently verified using seed-based cryptography or blockchain hashing.

For Solo Games (e.g., Mines, Crash, Wheel):

• Results are based on combined client and server seeds.
• You can reveal and verify these after each round.
• SHA-256 hashes are used to ensure pre-game commitment to outcomes.

For Multiplayer Games (e.g., Mines Battle, Case Battle):

• CobaltLab integrates EOS blockchain hashes into the outcome generation.
• This makes multiplayer sessions tamper-proof and fully traceable.
• The system ensures that neither the player nor the server can predict or alter the results once a game starts.

With this level of transparency, users can confidently play knowing that fairness isn’t just promised – it’s provable.
