To make sense of "casino bonus terms", 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 exchange.
No deposit bonuses give a small amount of credit or a few spins for registering, with no payment at all. The conditions are the tightest of any offer: high wagering, a low cap on what can be withdrawn and a short deadline. Identity checks usually come before any withdrawal, and one such offer is allowed per person or household. Treated as a free look at a casino, a no deposit bonus is useful; treated as a way to earn, it seldom is.
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 earns nothing at all.
Some offers only apply when a box is ticked before payment, and a deposit made without opting in usually earns nothing afterwards.
Bonuses that return after the welcome package, often weekly, with smaller matches and the same kind of wagering attached.
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.
A match bonus adds a percentage of the deposit up to a stated maximum, so a full match doubles a deposit under the ceiling and adds nothing above it.
Not always. Terms often exclude certain methods, commonly electronic wallets and prepaid cards, from welcome offers.
A sticky bonus is removed at withdrawal, leaving only the winnings above it, while a cashable bonus joins the balance once wagering is met.
