Casumo bonus terms and conditions

Casumo bonus terms and conditions in plain English

Every UK casino bonus has two layers of rules: the short list of significant terms shown next to the offer, and the full promotion and general terms behind them. Casumo's significant terms for its welcome offer are short, and the table below lists each clause with a plain reading. For the offer in context, see our main Casumo casino bonus page; for the general approach to reading terms, our bonus terms explained guide goes clause by clause across the market.

These are the key terms as last checked on 5 October 2026. Casumo's full terms on its website are the binding version, and offers can change. 18+, terms apply.

Who can claim: the eligibility and opt-in clauses

The offer is for new customers aged 18 or over. Age and identity must be checked before you can deposit or gamble, a rule in force since 7 May 2019; see our page on age verification before play. The opt-in clause means the bonus is a choice: if you skip it at sign-up or in the cashier, a later request may not be honoured. Our guide on how to opt in to a bonus shows what this usually looks like.

Welcome offers are normally limited to one per person, household or device, and holding more than one account is a breach of almost every casino's general terms. That is explained on our multi-accounting glossary page. Casumo is run by Recro Limited, which holds UKGC account 61549, so its terms are written under UK rules.

The qualifying deposit clause in Casumo's terms

Casumo's site says its general minimum deposit is £10 for all payment methods, but the welcome offer needs at least £20 on the first deposit. A £10 or £15 first deposit would therefore miss the bonus, and the clause refers to the first deposit only, so a second deposit cannot be used to qualify instead. The detail is on our Casumo minimum deposit page and the general term is defined under qualifying deposit.

The 50% match means the bonus grows with the deposit until £200, where it hits the £100 bonus cap. A £20 deposit gives £10; £60 gives £30; £200 or more gives £100.

Wagering and time limit clauses

The wagering clause asks you to play through the bonus 10 times within 7 days. Ten times is the most any UK-licensed casino can ask for since 19 January 2026. The 7-day period is the tighter constraint: £1,000 of play in a week on the full bonus works out at about £143 a day. Full worked figures are on our Casumo bonus wagering requirements page.

On average, wagering costs the house edge of the games you play. At 96% RTP, £1,000 of slot play costs around £40, leaving the £100 bonus worth about £60 on average. The bonus does not alter the odds of any game, and individual results vary widely.

The £5 max bet clause

While a bonus is active, no single bet may exceed £5. This is one of the most common ways bonuses are lost, because it applies to every bet, including a single over-limit spin late in the week. Separately, UK law limits online slot stakes to £5 per spin for players aged 25+ and £2 for those aged 18 to 24. More examples are on our Casumo bonus max bet page.

Game, play and payment restrictions explained

The significant terms bundle three restrictions into one line. Each one points to detail in the full terms.

• Game restrictions: which games can be played with the bonus and how much each counts towards wagering. See Casumo bonus eligible games.
• Play restrictions: betting patterns the casino treats as against the spirit of the bonus, often called irregular play. The Gambling Commission expects prohibited play to be clearly specified rather than left to the operator's judgement.
• Payment restrictions: deposit methods that do not qualify for the bonus. Casumo's offer says payment restrictions apply but the summary does not name the methods, so check the full terms. Our Casumo payment methods page explains how to check.

We do not give tips for getting round any of these. Breaking a restriction usually means the bonus and its winnings are removed, which is covered in what happens if I break bonus terms.

What UK rules say Casumo's bonus terms must do

Bonus terms are not just a contract the casino writes as it likes. Since the CMA's 2018 undertakings, and in the Gambling Commission's guidance, several protections apply to every licensed operator:

You can read the regulator's own wording on transparency of significant terms (opens in a new tab), on changing a promotion after opt-in (opens in a new tab) and on terms giving undue discretion (opens in a new tab). The ASA's advice on promotional terms and conditions (opens in a new tab) sets the same expectation for adverts. Our CMA bonus principles page summarises them.

How to read the Casumo bonus terms before you deposit

1. Open the welcome offer's significant terms and the link to the full promotion terms.
2. Note the minimum deposit (£20), the 50% rate and the £100 cap, and decide on a deposit you are comfortable losing.
3. Find the list of excluded payment methods and make sure your chosen method is not on it.
4. Find the game contribution list and the excluded games.
5. Write down the 7-day deadline and the £5 max bet.
6. Look for any cap on winnings from the bonus; our checked key terms do not list one, so confirm in the full terms.
7. Only then opt in and deposit.

Our casino bonus checklist turns these steps into a printable list.

Terms people commonly miss on the Casumo bonus

Most lost bonuses come from a handful of clauses rather than from anything hidden. In the Casumo offer the likeliest slips are a first deposit under £20, forgetting to opt in, depositing with a method the terms exclude, one bet over £5, and running out of the 7 days. Our list of bonus mistakes covers these and more across UK casinos.

If you think a term was applied unfairly, complain to Casumo first; the Commission's guidance gives a business 8 weeks to resolve a complaint before you can go to an independent ADR provider. Our page on Casumo bonus complaints walks through that process.

How Casumo's terms compare with a no-wagering offer

Shorter terms are not automatically better terms, but fewer conditions do mean fewer chances to slip up. PlayOJO's welcome offer has a different shape entirely: 80 free spins on Big Bass Bonanza at 10p each (£8 of spins) on a first deposit of £10 or more, with no wagering, for new UK customers excluding Northern Ireland, 18+. It can't be combined with other offers and must be claimed through the designated offer link.

Claiming the Casumo bonus on these terms

The Casumo offer box below links to the welcome bonus described here: 18+, new customers, opt-in required, 50% bonus up to £100 on a first deposit of at least £20, bonus wagered 10x within 7 days, max £5 per bet, game, play and payment restrictions apply. Read the full terms on Casumo's site, which is the binding version.

PlayOJO is listed second as the closest alternative for anyone who prefers no wagering: 80 spins at 10p on a first deposit of £10+, new UK customers excluding Northern Ireland, 18+, terms apply. Whichever you choose, set a deposit limit first and treat the bonus as extra entertainment rather than a way to make money.

18+. Gambling should be entertainment that costs money, not a way to make it. Decide a budget before you play: set a budget. Free, confidential help: National Gambling Helpline 0808 8020 133.
