To make sense of "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 single step. Taking the package apart shows what each deposit actually earns and what it asks in return.
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.
Packages split across several deposits release each tier only after the previous one is claimed, and often only within a set number of days of registration. Later tiers tend to carry smaller percentages. Each tier normally has its own wagering requirement, and some casinos stack them, so an unfinished requirement from the first deposit blocks the second. Reading the tiers as separate offers, each with its own cost, shows which of them are worth claiming.
A sticky bonus is removed at withdrawal, leaving only the winnings above it, while a cashable bonus joins the balance once wagering is met.
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.
Some offers only apply when a box is ticked before payment, and a deposit made without opting in usually earns nothing afterwards.
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.
Bonuses that return after the welcome package, often weekly, with smaller matches and the same kind of wagering attached.
Not always. Terms often exclude certain methods, commonly electronic wallets and prepaid cards, from welcome offers.
