Offer structures, without the hard sell

This page explains how common UK online casino promotions are built. It is factual and evergreen. Spin Selection does not attach “best” or “guaranteed” language to any figure, and we do not invent precise welcome amounts here — check each operator’s own terms.

Welcome offers

A welcome package is usually a match-style bonus, a bundle of free spins, or a hybrid of both, sometimes split across the first few deposits. Sports-led brands such as Star Sports or TigerBet may frame the first offer around betting with a casino add-on; casino-first brands lean toward spins or slot match language. Opting in is a choice — you can often play without the bonus if the terms feel awkward.

Free spins

Spins are typically locked to named games and carry a maximum conversion value. Winnings from spins often sit in a bonus balance until wagering is met. Because our comparison angle favours live casino, remember that spins rarely contribute much — if anything — toward clearing a bonus when you sit at a dealer table.

Cashback

Cashback returns a portion of net losses over a period, sometimes as bonus funds with their own playthrough. It is a cushioning mechanic, not a profit promise. Read whether cashback is calculated on slots only or across live games too.

Wagering requirements

Wagering (playthrough) states how many times you must stake bonus funds — or bonus plus deposit — before withdrawal of related winnings is allowed. Game weighting matters: slots might count 100%, while blackjack or roulette count far less or zero. That is why a live-casino-heavy session can clear a bonus slowly even if you are active for hours.

Practical checks before you opt in

• Time limit to complete wagering
• Max stake while a bonus is active
• Which games contribute, especially live tables
• Whether the offer conflicts with other promotions

On our homepage we only note offer type in the criterion list. For safer play tools that sit above any promotion, see responsible gambling.
