What’s included: FatBoss runs a first-deposit welcome offer worth up to £200 with 100 free spins. The match pays at 100% on your first deposit, so a £20 deposit adds £20 bonus funds, and a £200 deposit adds £200 bonus funds. The 100 free spins are credited as one bundle on a selected slot and any winnings from the spins are added as bonus funds.
How to claim (step by step):
Wagering requirements: Bonus funds and free-spin winnings come with a 35x wagering requirement. That means if you take a £50 bonus, you need to place £1,750 in qualifying wagers (£50 × 35) before the bonus balance converts to cash. Only real-money cashouts are possible after meeting the wagering requirement, and bets above £5 per spin while wagering can void the bonus.
Time limit: You get 7 days to use the 100 free spins after they are credited, and 30 days to complete wagering on the bonus balance. If the deadlines pass, the remaining bonus funds and any related winnings are removed from the account.
Open the FatBoss site, tap Sign Up, enter your email and a password, then confirm the email link. After that, fill in your name, address, and date of birth so deposits and withdrawals work normally.
Open the Promotions page and tap the specific welcome offer to see the full terms. You’ll see the wagering multiplier, the maximum bet allowed while wagering, and which games count before you claim it.
FatBoss accepts Visa and Mastercard in most supported countries, and the minimum deposit is £10 or the equivalent in your account currency. If your bank blocks gambling transactions, switching to a wallet option inside Cashier usually fixes it.
E-wallet withdrawals are commonly paid within 0–24 hours after approval, while card and bank withdrawals can take 2–5 business days. “Pending” means the casino is running security checks or you still need to pass verification.
Upload a photo ID and a proof of address in the Verification section, then wait for the review result in your account. If you deposited by card, you may also need to upload a masked photo of the card showing only the last 4 digits.
You can play directly in your mobile or desktop browser with no download. FatBoss runs on a responsive site, so slots and live casino load from the same account.
Use Live Chat from the Help section for the fastest reply, or email support if you need to attach screenshots. Keep your transaction ID and the exact time of the issue ready, because support will ask for both.
