Sign In
Logging in to Prism Casino gets you straight to the action and into the current Welcome Bonus: a 450% deposit match plus 300 free spins with bonus code THEBIG450. That promotion — especially for crypto deposits — is running with limited availability, so sign in to your account, enter the code, and confirm eligibility while the offer stands. New players also have access to a no-deposit bonus and daily free spins, so the moment you authenticate your account you’ll see multiple ways to grow playtime and potential returns.

Secure access and flexible funding options
Prism supports both fiat and a broad range of cryptocurrencies, so signing in opens fast deposit methods and crypto-specific promos. Available payment methods include Visa and MasterCard, Bank Wire Transfer, Neteller, Western Union, and a full crypto roster: Bitcoin (BTC), Bitcoin Cash (BCH), Ethereum (ETH), Litecoin (LTC), Dogecoin (DOGE) and Ripple (XRP). Currencies accepted range from USD to Bitcoin, Litecoin, Bitcoin Cash, Dogecoin and Ethereum — ideal if you prefer crypto banking or want traditional card transfers.
Account verification after sign-in clears the way for instant deposits and quicker withdrawals where eligible. If you plan to use bonus codes or promos, make sure your account has no pending withdrawal and meets the bonus terms before claiming.
Immediate perks after signing in — from free spins to VIP treatment
Once signed in you’ll see the full promotional lineup: the headline 450% + 300 free spins Welcome Bonus (THEBIG450), daily 60 free spins, occasional no-deposit rewards for newcomers, and frequent deposit bonuses. VIP members enjoy elevated deposit matches, cashback options, special tournaments, a personal VIP host, tailored promos and birthday bonuses up to $2,500.
Cashback programs are detailed and generous: a monthly cashback draw can return up to 30% of last month’s net losses (up to $5,000), while weekly cashback drops can return up to 45% of the prior week’s net losses (up to $1,000). These cashback offers carry a 30x wagering requirement; as always, review individual bonus terms before accepting any promotion since bonuses cannot be combined and some coupons won’t apply if you have a pending withdrawal or existing balance.
