Start With the Wagering Requirement, Not the Headline Figure
A generous-looking bonus means very little until you have checked the playthrough attached to it. In the United Kingdom, most licensed operators publish wagering requirements somewhere between 30x and 65x, and the gap between those figures changes the real cost of an offer dramatically.

Take a £100 bonus at 35x wagering. You must stake £3,500 before any of it converts to withdrawable cash. The same £100 at 65x demands £6,500 in qualifying bets. On that maths alone, the lower multiple wins even if the headline amount is smaller.
Check whether the multiple applies to the bonus alone or to bonus plus deposit. A 30x requirement on a £50 bonus and £50 deposit means £3,000 in play, not £1,500. The distinction is printed in the terms, usually under a heading marked ”significant conditions” , read that section first.
Match the Offer to How You Actually Play
Every bonus has a personality. Free spins suit slot players who want low-stakes entertainment with a capped upside, while deposit matches reward larger bankrolls spread across a longer session. Comparing them fairly means comparing them against your own habits.
Weigh up the details that quietly decide value:
- Game weighting , slots typically contribute 100%, but table games often count at 10% or less, which stretches a requirement fivefold.
- Maximum bet while wagering , commonly capped at £5 per spin or hand. Exceed it and the bonus can be voided.
- Spin value , 50 spins at 10p each is £5 of play. Always compare the cash equivalent, never the spin count.
- Expiry , 7 to 30 days is standard. A short window plus a high multiple is a red flag.
According to UK Gambling Commission data, slots account for roughly three-quarters of online casino gross gambling yield, so weighting rules rarely trouble pure slot players. If you drift towards roulette or blackjack, the arithmetic shifts sharply.
Read the Withdrawal Caps and Eligibility Rules
Winnings caps are the most overlooked term in bonus comparison. Some offers cap total winnings from free spins at £50 or £100; others impose a maximum conversion of the bonus itself. A 100% match sounds premium until you discover the conversion ceiling sits at £200.
Check payment method eligibility too. Deposits made via certain e-wallets may be excluded from bonus qualification, and the same restriction often applies to Skrill and Neteller. If your usual deposit route is excluded, the offer is effectively invisible to you regardless of its merits.
Finally, count the overall cost honestly. Add the deposit, note the playthrough, and estimate the expected loss at typical slot return-to-player figures of 94-96%. That calculation converts marketing language into a number you can compare across three or four sites in minutes.
