Offer shapes, not offer shouts.

UK casinos mostly recycle the same few bonus structures. Knowing the shape helps you read any brand — including the five on our homepage — without treating the headline as the whole deal.

Educational overview — not a promotion for any single offer.

Deposit match

The operator adds bonus funds equal to a percentage of a qualifying deposit, up to a cap. Those funds usually sit as bonus balance until wagering is met. Game contribution matters: slots may count 100%, while many table and live games count less or zero.

Free spins

A set number of spins on named slots, each with a fixed stake value. Winnings may be paid as cash or as bonus money that still needs wagering. Expiry windows are often short. Always check eligible titles — a spin on a game you dislike is still a spin used up.

Cashback

A percentage of net losses returned over a period, sometimes as bonus funds with lighter wagering, sometimes as cash. Cashback is not a win booster; it softens a losing stretch after the fact. Caps and excluded games still apply.

Wagering requirements

A multiplier tells you how many times you must stake bonus funds (and sometimes the deposit) before withdrawal. Example pattern: £20 bonus at x30 means £600 of qualifying stakes. Max bet rules during wagering are common — break them and the operator can void the bonus.

Quick checklist before you opt in

  • Multiplier and whether the deposit is included
  • Game weighting and excluded titles
  • Max bet while the bonus is active
  • Time limit to finish playthrough
  • Country and account eligibility (UK login, one welcome per person/household)

How this maps to our shortlist

888 Casino often leads with a classic match package. NYSpins frequently blends match and spins. Voodoo Dreams leans spin- or fund-led. Midnite tends to publish caps clearly in-product. TigerBet’s combined sport-and-casino packaging needs a careful read of which product’s rules apply. None of that is a promise that today’s banner matches yesterday’s — open the live terms.
