Grade: F
Monster Treasure has closed and is no longer operating, so there is no safe way to play there or redeem a balance. SweepsGuard keeps its record published so players can see how the site behaved before it shut down.
Update (August 2026): Monster Treasure is offline. Every address on monstertreasure.com now returns a 404, including the homepage and each of the site's main sections; the www address no longer resolves at all. What is left is a stripped application shell that cannot load its own content. No closure notice was posted and no final redemption window was offered before the site went down.
Monster Treasure was a sweepstakes casino operated by MTreasure Labs Inc., a Texas corporation registered at 1999 Bryan St. Suite 900, Dallas, TX 75201. It launched with a standard selection of slots and casino games on a dual-currency sweepstakes model. It was blacklisted before it closed, over a documented pattern of denied redemptions, a broken refund agreement, and unexplained account closures — and the closure does not retire that finding.
Player reception was consistently negative throughout the platform's life. Reviewers reported redemption difficulties, conflicting explanations from support, and no meaningful resolution when disputes arose. The pattern was unmistakable: purchases went through without trouble, while redemptions were routinely denied or stalled.
Monster Treasure prioritized taking player money over honoring its own commitments. It accepted purchases, denied pending redemptions with a generic justification, offered a refund it never delivered, and closed the account. It has now exited without telling anyone. One case did end better than most: after SweepsGuard mediation, Monster Treasure reopened a previously closed account and paid a $1,000 redemption to a player in Ohio, though a second redemption was canceled under a one-at-a-time rule.
Do not attempt to fund an account — the platform is gone. This listing stays published permanently as a record for anyone searching the name, and the blacklist designation stands on the conduct documented while the site was live. If you were holding a balance when it went dark, file a report with us so the loss is on the record; that history is what lets us recognize the operator if MTreasure Labs Inc. reappears behind another brand.

Full Monster Treasure complaint history
Monster Treasure's final SweepsGuard grade was F, last updated June 20, 2026. The site has since closed, so that grade is a record of how it behaved while it was running, not a live assessment.
You can, but Monster Treasure is closed, so there is usually nobody left to answer and unpaid balances are rarely recovered. We still log every report at sweepsguard.com/submit-complaint, and it still helps: it keeps the public record accurate and it tells us if the same operator turns up again under a new name.
