Grade: C
Launched in October 2023, Stackr Casino is operated by Stackr Social, LLC and has quickly established itself as a crypto-focused sweepstakes casino in the US market. The platform features 600+ games from notable providers including Hacksaw Gaming, Nolimit City, Betsoft, and Backseat Gaming. Stackr made headlines by becoming the first sweepstakes casino to bring Nolimit City games to the US market. With a 4.3/5 Trustpilot rating and a focus on cryptocurrency redemptions, Stackr appeals to players seeking fast payouts and modern game selections.
Stackr maintains a 4.3/5 rating on Trustpilot based on 3,000+ reviews, reflecting generally positive but mixed player experiences. The majority of positive reviewers praise the fast crypto redemptions (often within 24-48 hours), extensive game selection, and responsive customer support when accessible. However, several players report account closure issues related to alleged duplicate accounts, verification delays, and the restrictive $500 daily withdrawal limit. The platform responds to approximately 61% of negative reviews, though response times typically exceed one month. As a newer platform launched in late 2023, Stackr is still building its long-term reputation in the industry.
Since launching in October 2023, Stackr has maintained a generally positive record with successful crypto redemptions reported by many players. The platform has demonstrated commitment to processing payments, particularly via cryptocurrency, with many users praising the speed of crypto withdrawals. However, as a newer operator, some growing pains have been reported including occasional account closure disputes and verification challenges. The company responds to player concerns and maintains communication channels, though response times can be lengthy. The platform has shown willingness to address legitimate issues when they arise, and the majority of players report successful redemptions when following proper verification procedures.
SweepsGuard has received two complaints about Stackr Casino, and in both cases the platform did not respond or engage with the mediation process. The most recent (Case #66) involved a Wisconsin player who reported a $123 redemption reduced to $100 before their account was banned, with Stackr citing a rule that bonus Sweeps Coins must be played rather than accumulated; the casino did not respond to mediation. A second unanswered complaint is a growing concern, and continued non-engagement will weigh against the grade on the next review. The lack of response to a player complaint is a notable concern, particularly for a newer operator still building trust with its player base. Combined with the crypto-only payment model, relatively high $100 minimum redemption, $500 daily withdrawal cap, and slow response times to negative Trustpilot reviews, there are enough friction points to warrant caution. While many players do report successful redemptions and the game library is strong, the unwillingness to engage with third-party complaint resolution raises questions about long-term support reliability. We encourage players to complete verification early, maintain realistic expectations regarding withdrawal limits, and understand that bonus winnings are capped at 100 SC monthly. Should the casino begin engaging with complaints or demonstrate improved responsiveness, we will revisit this assessment accordingly.
