For "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 The conditions are the tightest of any offer: high wagering, a low cap on what can be withdrawn and a short deadline.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.
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.
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 sticky bonus is removed at withdrawal, leaving only the winnings above it, while a cashable bonus joins the balance once wagering is met.
Every offer names a qualifying deposit, and a payment below that minimum earns no bonus at all.
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.

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.
