Grade: closed
Grand Vault Casino was a sweepstakes casino operated by 247 Entertainment LLC (registered in Delaware) with platform management support from AppGreat EU SRL and National Sweepstakes Group LLC — the same partnership behind Spins America and Spin4America, both of which are blacklisted by SweepsGuard. Grand Vault launched in September 2025 and appears to have shut down by mid-2026, with its domain (grandvaultcasino.com) no longer resolving.
Grand Vault had limited independent player feedback during its short lifespan. Third-party review sites generally described it as functional but unpolished, with email-only customer support and a modest game library of 350–500 titles. The site shared the same operator ecosystem as Spins America, which holds a 2.5 out of 5 on Trustpilot with over 120 reviews dominated by complaints about stonewalled redemptions and unresponsive support.
Grand Vault was the second sweepstakes platform launched by National Sweepstakes Group LLC and AppGreat EU SRL, following Spins America (December 2024) and preceding Spin4America (early 2026). The site operated for approximately 8–9 months before its domain stopped resolving. The rapid cycling of brands — three sites in under 18 months, with the second already shut down — reinforces concerns about the operator's commitment to sustained, good-faith operations.
Grand Vault Casino is marked as Closed on SweepsGuard. The site's domain no longer resolves and the platform appears to have ceased operations. Players who had active balances or pending redemptions at Grand Vault should contact support@grandvaultcasino.com, though the responsiveness of that channel is uncertain given the site's apparent closure. Grand Vault's parent operator, National Sweepstakes Group LLC, continues to operate Spins America and Spin4America, both of which are blacklisted by SweepsGuard.
