BK8's VIP programme runs five tiers — Bronze, Silver, Gold, Platinum, Diamond — with promotion triggered automatically by cumulative qualifying activity (deposits and/or turnover) over a rolling window. You don't apply; the system tracks your activity and promotes when thresholds are met. Demotion is also automatic if activity drops below the tier-maintenance threshold for a cycle. Tier status is account-level (not per-product), so activity across sportsbook, slots, live casino and the rest all contributes to the same tier-promotion counter.
Each tier unlocks four kinds of benefit: higher cashback rates than the standard slate (see /promotions/cashback), faster withdrawal processing lanes, larger birthday and seasonal credits, and — at Platinum and Diamond — a dedicated VIP account host as a named contact. The upper-tier benefits are the part most readers underestimate; host access in particular is harder to put on a comparison table but materially changes how the account works.
