Bonus terms — fairness check

Fair terms

No high-risk clauses flagged in the terms we hold — standard, player-friendly wording.

Auto-flagged from the operator's own bonus terms (quoted verbatim) — not legal advice. No flag means our checks found none in the terms we hold, not that the terms are perfect. Always read the full T&Cs.
