Begin with your intended deposit
Put your intended deposit beside both offers before looking at the largest number in either advert. Two sister casinos can promote very different packages despite a clear operator connection. If reaching a package maximum would mean depositing far more than you planned, that maximum is not the figure that should decide between them.
Now check whether you can actually claim each offer. Existing-customer rules and related-brand conditions may affect eligibility. Leave that point marked as unresolved until you have an answer; there is little value in carefully ranking a package you might not qualify to use in the first place.
This guide deals with the offer itself. The general sister-casino choice guide covers product fit and navigation. Keeping those decisions separate prevents an attractive reward from distracting you from a casino that lacks the game or room you wanted.

Put the same fields side by side
Record the current wording for each offer. Do not borrow an absent term from another brand in the same family.
| Field | What to establish | Why the headline is incomplete |
|---|---|---|
| Qualifying deposit | The amount and any eligible payment conditions | A package ceiling may require several stages |
| Reward | Cash, bonus credit, spins or another component | Different reward types are not equivalent cash amounts |
| Wagering basis | The multiplier and the funds it applies to | The same multiplier can produce different turnover |
| Game contribution | Which games count and at what rate | Your preferred game may contribute little or nothing |
| Limits and expiry | Stake limits, time window and any stated caps | A reward can be impractical despite a large total |
| Eligibility | The named customer conditions | A sister-site relationship does not guarantee another welcome offer |
Keep the offer URL and date with the comparison. Promotions can change independently of the operator relationship. An old family description is not evidence of today’s bonus terms.
A £20 example: read the base
The following figures are hypothetical, not offers at the casinos featured on this page. They show why the amount used in a wagering calculation matters.
Suppose both offers match a £20 deposit by 100%, giving £20 in bonus credit. Offer A requires 30 times the bonus. Offer B requires 30 times the deposit plus bonus. The advertised match and multiplier look the same, but the calculation is different.
| Hypothetical offer | Calculation | Required qualifying turnover |
|---|---|---|
| A: 30× bonus only | 30 × £20 | £600 |
| B: 30× deposit plus bonus | 30 × (£20 + £20) | £1,200 |
Turnover is the total qualifying stakes under the offer rules, not an additional deposit requirement and not a prediction of how much you will win or lose. The reward can be lost before any requirement is completed. The arithmetic describes the condition, not a strategy for profit.
Now consider contribution. If an eligible game counts at 50%, a £1 stake contributes 50p towards the requirement. A 0% contribution means that game’s stakes do not advance it. Read the actual contribution rules before assuming every casino game works the same way.
A percentage and a cap do different jobs
The percentage describes the match rate. The cap limits the bonus amount available under the stated terms. Neither tells you the other.
In a simple hypothetical 100% match capped at £100, a qualifying £20 deposit would generate £20 of bonus credit, not the full £100. Reaching the cap would require the qualifying amount described by that offer. This example assumes a straightforward one-stage match solely to illustrate the arithmetic.
A multi-deposit package is different. An advertised total can combine several deposits, spin allocations or other rewards. Separate the first stage from later stages and decide whether the first stage alone is relevant to your intended visit.
Do not increase the planned deposit just to make two package maxima comparable. The useful comparison is what each offer provides for the amount and activity you had already chosen, under its actual conditions.
Free spins and cashback need detail
A free-spin count leaves several questions unanswered. Which game is used? What is the value per spin? When do the spins expire? Are winnings cash or bonus funds, and are there conditions attached to them? Two identical spin counts can describe different rewards.
Cashback is another component with its own definition. Read the period used, the calculation basis, any cap and the form in which the reward is paid. A percentage without that context does not tell you the amount you would receive.
Keep recurring rewards separate from a welcome package. A promotion described as ongoing may use different eligibility or activity requirements from the first-deposit offer. Combining them into one impressive total can obscure the conditions that matter to your account.
The same care applies to bingo tickets and game-specific credits. A reward usable only in selected sessions should be compared with those sessions in mind. It is not interchangeable with cash or unrestricted casino play.
A sister account may matter
Read whether the offer addresses existing customers of related brands. A separate casino name does not automatically create a new-customer entitlement. Equally, a shared operator is not sufficient evidence that you are excluded. The named promotion’s wording must settle the issue.
If you already hold an account at one brand, ask the destination about that account and the exact offer. Include the current public link. A general question about sister sites may establish the company connection while leaving eligibility unresolved.
The account guide separates login and wallet questions from promotion eligibility. The Winomania profile provides a named example of operator-connected brands whose individual conditions still need their own reading.
Do not treat a working login or accepted registration as proof that every advertised promotion applies. Access and eligibility answer different questions.
Contribution changes the useful calculation
Return to the hypothetical £600 wagering requirement above. If the chosen game’s stakes contribute at 100%, each £1 qualifying stake advances the requirement by £1. If they contribute at 50%, each £1 advances it by 50p. At that rate, £1,200 in stakes would be needed to generate £600 of qualifying contribution, assuming all other terms are satisfied.
This is arithmetic, not a plan for completing the offer. Funds can be lost before the requirement is met, and the game rules and promotional conditions can impose other limits. The calculation simply shows why a contribution rate belongs beside the multiplier.
A lower wagering multiplier can therefore be an incomplete advantage if the game you intended to play contributes less. Compare the whole applicable condition, not one number in isolation.
A 0% game is different again: its stakes do not progress the requirement under that rule. The fact that a game is available in the casino does not mean it is eligible for the promotion.
Do not use a provider name as a shortcut. An offer may describe eligibility by individual title, category or another defined list. Read the actual wording at the destination.
The right question is practical: does this offer fit the game and activity I already intended? If not, its headline value is less relevant, even before comparing it with a sister casino’s package.
Two hundred spins can mean different rewards
Consider two hypothetical allocations of 200 spins. At 10p per spin, the stated spin stake value totals £20. At 20p per spin, it totals £40. Neither figure is a promise of cash winnings or an amount available to withdraw.
The game matters too. An allocation tied to a title you did not intend to play is not equivalent to unrestricted choice. Read whether the offer names one game, a selection of titles or a schedule of allocations.
Delivery can affect practicality. Spins might be available together or released in stages, depending on the actual terms. If a stage expires before your intended visit, the full headline count may not be relevant to you.
Then read the treatment of winnings. Are they paid as cash or as bonus funds with conditions? Does the promotion identify a cap or another restriction? The spin count supplies none of these answers.
This is why comparing spins solely by quantity can mislead. Keep count, stake value, game, delivery, expiry and winnings treatment as separate fields.
The example does not describe the live spin terms of LegionBet or SlotRoyals. Their actual conditions must be read at the destination. The figures here only demonstrate how two similar-looking headlines can represent different rewards.
A cashback percentage needs a definition
Suppose a hypothetical promotion offers 10% cashback, capped at £10, on a stated qualifying amount over a defined period. If the qualifying amount were £30, the percentage calculation would be £3. If it were £200, the percentage would produce £20 before the cap, but the stated cap would limit the reward to £10.
The important unresolved detail is what counts as the qualifying amount. A promotion may define its own measurement period, eligible activity and calculation. Do not assume it applies to deposits, stakes or any other figure without reading the terms.
The form of the reward matters as well. Cashback can be described in promotional language while its terms specify cash, bonus credit or another type of reward. Those forms should not be treated as interchangeable.
Check whether the reward is automatic, must be claimed or has an expiry. A recurring headline can still have a defined claim window or qualifying conditions.
Cashback is also not a reason to increase activity. The comparison should explain what the offer does under its own rules, not present the reward as a way to remove the cost or risk of gambling.
Keep the calculation beside the actual offer definition. A percentage copied without its basis, cap and reward type is too incomplete to rank fairly against another casino’s promotion.
Expiry and stake limits can decide the choice
A time window is part of the offer, not small print to consider after the headline. If the promotion requires qualifying activity within a period that does not suit the visit you intended, a larger reward may not be useful.
Read when the clock starts. It may be tied to registration, deposit, activation or another stated event. Do not assume the same trigger across two sister brands because the offers look similar.
Maximum-stake conditions are another separate field. If the promotion limits the stake permitted while using a reward, that rule can affect whether the offer fits the games and stakes you planned. The general game limit does not necessarily describe the promotional limit.
Keep any maximum conversion or winnings condition visible where the terms state one. A headline bonus ceiling and a withdrawal-related cap are different concepts; confusing them can make a package appear to offer something its conditions do not.
This does not mean that every offer contains every restriction. The method is to record what the actual terms establish, leave absent or unclear fields unresolved and avoid importing rules from another casino.
When a key condition is unclear, ask about that one term before activating the offer. A precise question about the start of an expiry period or an eligible game is easier to answer than “Is this a good bonus?”
A complete hypothetical comparison
Imagine two eligible offers for the same intended £20 deposit. One gives a larger bonus but limits the qualifying games to titles you do not normally choose. The other gives a smaller reward on the game you intended to play, with clearly stated conditions.
The larger reward is not automatically the better fit. Your original product choice still matters. Changing the game and extending the visit simply to pursue the larger package would be a different decision from comparing the two offers for the activity you planned.
Now suppose the smaller reward has an expiry you cannot use. That may remove its apparent advantage. A useful comparison can end with neither offer matching the intended visit.
The final note should identify the actual deciding condition: game eligibility, expiry, reward type, verified customer eligibility or another specific field. Avoid a general “best value” conclusion when the conditions do not support one for every customer.
The same method works whether the casinos share an operator or are independent. The relationship can affect which eligibility terms deserve attention, but it does not change the need to read the reward mechanics.
A complete comparison is therefore a modest piece of work: one planned deposit, two current offers, the relevant conditions and a clear reason for the outcome. It does not need a strategy for collecting every promotion in a family.
Keep the conclusion tied to the offer
When you finish, write down the exact promotion and the condition that decided the comparison. A conclusion such as “the selected game does not qualify” is more useful than a general judgement that the brand has poor bonuses.
Keep the current public link and date with that note. A later promotion can use different conditions even at the same casino, so the conclusion should not be carried forward automatically.
If eligibility or a key reward term remains unclear, state that as the reason the comparison is incomplete. Do not turn a missing answer into an invented advantage for the other package.
Choose on the condition that matters
After completing the comparison, identify the deciding difference. It might be a clearer reward type, a relevant eligible game, a manageable expiry or confirmed eligibility. There is no need to invent a numerical score if one of those conditions already rules an offer out.
The right outcome may be to use neither package. If both require activity you did not intend, or if a key term remains unclear, the headline amounts do not resolve that problem. A bonus comparison should help you understand the commitment rather than persuade you that some package must be chosen.
Use the comparison tool for the two named brands and the directory to find their relationship guides. The network pages explain the company link; the actual promotion page supplies the conditions.
For product comparisons such as 888 Casino and 888 Poker, first establish that the rewards concern comparable activities. A casino bonus and a poker promotion need their own product-specific reading before headline values can mean anything useful.
Two real package headlines to inspect
LegionBet and SlotRoyals are independent commercial comparisons. The hypothetical calculations above are not claims about either casino’s wagering terms.
| Casino | Welcome package | Offer |
|---|---|---|
| LegionBet | 125% Bonus up to £20,000 | LegionBet |
| SlotRoyals | Welcome Bonus 200% up to £1,700 + 200 FS | SlotRoyals |
LegionBet’s percentage and package ceiling differ from SlotRoyals’ match and spin allocation. Use the same intended deposit, then read the actual stage structure and reward conditions. The table preserves the displayed headlines; it does not supply missing terms.
