What players report
External Reputation Signal · Trustpilot / communityExternal review signal: low concernTrustpilot 4.1/5 (173 reviews) · Licensed; strong score, smaller sample
Well-rated: HighRoller scores 4.1 out of 5 on Trustpilot (173 reviews), with fast payouts and helpful support praised. Watch-outs are some accounts restricted after repeated wins and support that isn't 24/7. If you play, keep records if a winning account gets restricted.
External reputation signal from third-party player reviews — not a SlotAff safety verdict, Trust score or licence assessment. Player claims are reports, not verified facts.
Common complaints
- Some accounts restricted/banned after repeated wins
- Support not 24/7 (roughly 8am-1am CET)
- Occasional mid-session game crashes
Fair points
- Fast withdrawals — often within hours or minutes
- Friendly, professional customer service
