This comprehensive review provides the detailed research and analysis you need before downloading.

It operates outside official stores, requiring users to download the APK from its website or third-party sources.

Earning Methods

2. Casino & Slot Games

Trust & Scam Reports
- ScamAdviser flags big-mumbai.club with a low trust score due to hidden WHOIS data and phishing reports.
- Conversely, bigmumbai.in received a 61/100 medium trust score, but analysts still caution “medium-to-low risk”.
- Reddit threads warn users that the app itself cautions “be cautious as it may be a scam” — yet many still try their luck.
Withdrawal Experience & Complaints
Despite initial smooth payouts, withdrawal issues quickly surface:
- Pending for weeks: Users report funds stuck in “processing” status.
- Partial payouts: Some users receive less than requested.
- Unresponsive support: Customer service either delays or ignores tickets.
- A popular YouTube review highlights “withdrawal completed but never received” cases.
Major Red Flags
- APK-Only Distribution
- No Play/App Store listings bypass security vetting.
- Ponzi-Style Mechanics
- Old users paid with new deposits, unsustainable long-term.
- Opaque Ownership
- Developer identity hidden; no corporate address.
- Unrealistic Promises
- High multipliers on colour bets encourage reckless gambling.
- Inconsistent Trust Scores
- Mixed signals from scam-checking tools create confusion.
Verdict: Legit or Fake?
Big Mumbai Game may pay small amounts initially to build credibility, but its APK-only model, withdrawal failures, and Ponzi-style payout structure strongly suggest it’s a high-risk platform—not a sustainable income source. Proceed with extreme caution and never invest more than you can afford to lose.
