What is Maximum Win Cap?

A maximum win cap is the ceiling on what you may keep from a bonus, however much the games actually pay. Anything above it is removed before withdrawal. Caps come in layers and the tightest one governs. A single offer might cap free-spin winnings at €150, cap the cash bonus at the bonus amount itself — so a €1,000 bonus cleared perfectly returns at most €1,000 — and sit under a global ceiling of €10,000 across every promotion, tournament and loyalty prize the account ever receives. The headline percentage tells you almost nothing without these numbers. A 390% package with a per-stage cap equal to the bonus is a smaller offer than a 100% package with no cap, and the difference only appears in the terms. Check the cap before the match rate.
