CobaltLab Overview

CobaltLab is a Rust skins gambling platform centered around case openings and crate-based game modes. The site focuses heavily on solo case openings against the house and Crate Battles, where multiple players open the same set of crates and compete based on total item value. Additional game modes include Crash, Mines, Wheel, and duel-style head-to-head games.

CobaltLab Games

CobaltLab offers both PvP and house-controlled games. Crate Battles and similar battle formats are PvP, including 1v1, free-for-all, and team-based modes, where players compete based on the value of opened items. Standard case openings, Crash, Mines, and Wheel are house-controlled games. The platform explains each game’s rules but does not clearly label which modes are PvP or house-run. Many games use Rust-themed crates, scrap, and visuals, which do not affect mechanics or odds.

CobaltLab Fairness & RNG

CobaltLab states that game outcomes are generated using a provably fair system that combines server and client seeds with a future EOS blockchain block hash. The EOS blockchain is used as an external source of randomness, meaning results are not known before the relevant block is mined.

For standard games, outcomes are produced using HMAC-SHA256 with the server seed, client seed, nonce, and game parameters. The server seed hash is shown before betting starts, and the full seed is revealed afterward for verification.

For games such as roulette, case battles, and mine battles, the platform commits to a future EOS block at round creation. Once betting closes, the game waits for that block to be mined and uses its hash, combined with the round seed and game ID, to generate the final result. Verification data and example code are provided after the round.

CobaltLab Deposits & Withdrawals

CobaltLab supports a wide range of deposit methods. Users can deposit via cards, gift cards, bank transfer, Google Pay, Rust skins, and multiple cryptocurrencies, including Bitcoin, Ethereum, USDT, TON, Solana, Tron, Litecoin, BNB, and Avalanche.

Withdrawals are more limited than deposits. Supported withdrawal methods include Rust skins, Ethereum, USDT, and Litecoin. Deposited balances and items are custodial while held on the platform. The site does not publicly list minimums, fees, or guaranteed withdrawal processing times.

CobaltLab Bonuses

CobaltLab promotes multiple bonuses and reward systems, including free cases for new users, deposit bonuses via promo codes, task-based rewards, rakeback or cashback systems, and leaderboard-style competitions. The platform also features XP or level-based rewards.

Detailed bonus terms, wagering requirements, and eligibility restrictions are not clearly outlined in publicly visible pages.
