Player's complaint
Editorial note: most UK casino bonus terms cap the per-spin stake while bonus credit is active — typically £5 per spin. Auto-spin features and stake-bumping habits can breach the cap unintentionally, causing the operator to void the bonus and any winnings derived from it. The contractual basis for voiding is sound but the case is one of the most common sources of player frustration. Editorial recommendation: set the spin stake explicitly at a value below the operator's bonus max-bet before clearing wagering, and disable auto-stake-increase features.
