Strengths
Weaknesses
Cosmobet is a casino-sportsbook hybrid. Three years, 4,500 games from 48 providers. 18,000 monthly players. US score: 5.93/10. Casino Guru: 6.2/10. The game library and provider roster are competitive (Pragmatic Play, Evolution, Play'n GO). The three-year track record is the main limitation. The 67% complaint resolution rate needs improvement. For US players who want casino and sports in one crypto-friendly platform, more established options exist.

“Casino-sportsbook hybrid. Young brand with limited complaint data. KYC delays and bonus disputes are the main issues. 67% resolution rate is below average. The sportsbook side generates additional complaints around voided bets. No confirmed nonpayment patterns. Three years is too early for definitive trust assessment.”
Three years. Nexus Group Enterprises N.V. 18,000 monthly players. Casino Guru: 6.2/10. 67% resolution rate. Trust tier: newer. Too early for definitive conclusions.
