For "free spins add card", start with how the offer is built. A welcome offer is rarely one bonus. It is usually a package spread across several deposits, each with its own match percentage, ceiling and conditions, and sometimes with free spins attached. The headline adds the parts together, which makes the whole look larger than any one step. Taking the package apart shows what each deposit actually earns and what it asks in exchange.
Reload offers return after the welcome package, often weekly, with smaller matches and the same kind of wagering. Whether any bonus is sticky or cashable matters as much as its size. A sticky bonus can be played with but is removed at withdrawal, so only the winnings above it can be cashed. A cashable bonus becomes part of the balance once the requirement is met. The terms name the type, sometimes under a different label.
A match bonus adds a percentage of the deposit, up to a ceiling. A hundred percent match up to a stated maximum doubles a deposit that stays under the ceiling, and adds nothing to the part above it. Higher percentages usually come with lower ceilings or heavier wagering. Comparing offers by the bonus a planned deposit would actually receive, instead of the largest figure in the banner, keeps the comparison honest and often reverses the order of two competing offers.
Every offer names a qualifying deposit, a minimum below which no bonus is paid. Some also require a code at the cashier or a tick in an opt in box before the payment, and a deposit made without it rarely earns the bonus afterwards. Certain payment methods, often electronic wallets and prepaid cards, are excluded from welcome offers in the terms. Checking the method and the code before paying avoids a deposit that quietly earns nothing.
A sticky bonus is removed at withdrawal, leaving only the winnings above it, while a cashable bonus joins the balance once wagering is met.
Each tier unlocks only after the previous one is claimed, often within a set number of days from registration, and later tiers usually match smaller percentages.
No deposit offers give credit or spins for simply registering, so casinos pair them with high wagering, a low withdrawal cap, a short deadline and one claim per household.
Every offer names a qualifying deposit, and a payment below that minimum earns no bonus at all.
