Betting Promotions in Ireland Explained: Free Bets, Deposit Matches, Acca Insurance and What an Offer Is Really Worth

Updated 20 Oct 2026 · By the IrishBetGuide Editorial Team

"Bet a tenner, get thirty in free bets." You've seen the ads on the side of a bus, in the middle of a match and all over your phone. Then there are the offers for people who already have an account: acca insurance, price boosts, money back specials, loyalty schemes. Some of these promotions are worth a few euro to a careful punter. Some are worth close to nothing once you read the terms. And a few are built to get you betting far more than you planned. This page shows you how to tell which is which, with the sums done in plain numbers.

18+ only. Every offer, price and stake on this page is a made-up example to show the maths, not a real promotion. Cloudbet, which we link to, is licensed in Curaçao and is not licensed by the Gambling Regulatory Authority of Ireland (GRAI).

The main kinds of betting promotion

Almost every promotion you'll see from a bookmaker, whether it's for new or existing customers, falls into one of a handful of shapes. Once you can name the shape, you can price it.

Notice how few of these hand you cash. Most hand you something that can turn into cash if certain things happen. That's where the value leaks out, and that's what the rest of this page is about.

Promotions for existing customers

Once you have an account, the offers keep coming. These are usually smaller than welcome deals, but because they repeat every week, their value (or cost) adds up over a season.

Acca insurance is a good one to price, because it's sold as a big deal. Say you place a five-leg acca at about 1.80 a leg, combined odds of roughly 18.9. If each leg has a fair chance of about 53%, the chance exactly one leg fails is roughly 5 × 0.53⁴ × 0.47, which comes to about 19%. So about one time in five you get a free bet back. If that refund is a €10 free bet worth about €7, the insurance is worth roughly €1.30 per acca on average. Meanwhile the acca itself, with five lots of margin stacked on top of each other, costs you far more than that over time. Insurance takes a little of the sting out of accumulators. It doesn't fix them.

Weekly bet clubs work the same way in reverse: they're worth something only if you'd have placed those bets anyway. If you're adding an extra €20 a week of betting just to qualify for a €5 free bet, the club is costing you money.

Free bets: the "stake not returned" catch

A free bet is not the same as €10 of your own money. When a normal €10 bet at 3.00 wins, you get €30 back: €20 profit plus your €10 stake. When a €10 free bet at 3.00 wins, most bookies pay you €20. The stake isn't returned, because it was never yours. Bookmakers call this SNR, short for "stake not returned".

That one rule means a free bet is worth less than its face value, and how much less depends on the odds you put it on. Here's the rough value of a €10 free bet at different prices, allowing for a typical bookmaker margin of about 5%:

The formula behind the last column is simple enough: free bet × (1 − 1 ÷ odds), then knock off a little for the margin. The pattern is the useful bit. A free bet on a short-priced favourite throws most of its value away. A free bet on a bigger price keeps more of it, but you'll lose the token most of the time. That's fine if you understand it's the long-run average that counts. It's not fine if you'd be gutted to see it go.

A sensible middle ground for most people is to put free bets on prices somewhere between 3.00 and 6.00. You keep a good chunk of the value without turning every token into a lottery ticket.

Pricing a whole "bet €10, get €30" offer

Let's run a full example. The offer says: bet €10 at odds of 1.80 or bigger, and when it settles you get three €10 free bets.

• The qualifying bet: €10 at 1.80. With a 5% margin built into the price, your average cost is about 50 cent. Win or lose on the day, over the long run you give up roughly 5% of your stake.
• The free bets: three tokens of €10. Placed at around 4.00 each, they're worth roughly €7.10 each, so about €21 between them.
• Total: about €21 of value for a 50 cent average cost, so close to €20 in your favour on average.

That's a genuinely decent deal, on paper. Now the catches that can shrink it:

• The free bets expire in seven days and you forget to use them.
• They're restricted to one sport, one market or a minimum price you don't like.
• You have to place them as accumulators with three or more legs.
• They come in odd-sized chunks, like five €2 tokens, that are awkward to use.
• The qualifying bet has to be your first bet, and you'd already put a euro on something.

Every one of those knocks a few euro off. Read the terms before you deposit, not after.

Money back if your first bet loses

This one sounds like a safety net. Bet up to €20, and if it loses you get it back. Almost always, though, you get it back as a free bet, not as cash.

So the real value is: the chance your first bet loses × the value of the free bet. If you back something at 3.00 with a €20 stake, it loses roughly two times in three. The €20 free bet you'd get, used at a sensible price, is worth maybe €13 to €14. Two-thirds of that is about €9. Not bad, but a long way from "risk-free", which is a phrase you should treat as a red flag in any ad.

The trap is psychological. People bet bigger and longer on the first bet because "it's covered". Then the refund comes as a free bet with restrictions, and the €20 has to be bet again before it's worth anything.

Deposit match bonuses and wagering

Deposit matches are more common at casinos and crypto sites than at traditional Irish bookies, but you'll see them. The deal: deposit €100, get €100 in bonus funds. The catch is wagering, sometimes called rollover or playthrough. You have to bet a set amount before you can withdraw the bonus or anything you win with it.

Wagering is where these offers live or die. The more you have to bet, the more the bookmaker's margin eats. Here's what happens to a €100 bonus on a €100 deposit under different rules, assuming roughly a 5% average margin on sports bets and about 4% on slots:

That last row is the type you see a lot at offshore casinos. On average, you'd expect to burn through the bonus and a fair chunk of your deposit long before you're allowed to withdraw. These are averages, so some people get lucky, but you can't plan on being one of them.

Other terms to look for with deposit matches:

• Minimum odds: bets under 1.50 or 2.00 often don't count.
• Maximum bet: going over a small stake while the bonus is active can void your winnings.
• Game weighting: at casinos, table games may count 10% or nothing towards wagering.
• Maximum cashout: some bonuses cap what you can win from them.
• Time limit: unfinished wagering after seven or thirty days wipes the bonus.
• Withdrawal lock: asking for a withdrawal can cancel the bonus completely.

Enhanced odds for new customers

"Get the favourite at 10/1!" These look massive, but check the maximum stake. If the boost is capped at a €1 stake and the extra winnings come as free bets, the most you can gain is a few euro. They're a fun little extra, nothing more. Our page on Cheltenham bet boosts walks through how to value a boost properly, and the same test works for any sport.

Casino free spins

Free spins are the casino version of a free bet. A typical deal might be 50 spins at 10 cent each, which sounds like €5. Run through a slot with a 96% return-to-player figure, the average result is about €4.80 in winnings.

Then the wagering kicks in. If those winnings have to be wagered 35 times, that's about €168 of further spins. At a 4% house edge that's an expected cost of over €6, more than the winnings themselves. You can't lose more than the bonus money in that case, but on average very little survives to the withdrawal stage. Treat free spins as a free go on a game, not as money.

We've looked at this in detail for one brand on our page about the Cloudbet casino no deposit bonus, and our guide to online slots for Irish players explains RTP and volatility without the jargon.

Crypto welcome packages

Crypto books often skip the classic free bet and run a welcome package that drips rewards back to you over a set period, based on how much you bet. When we checked in October 2026, Cloudbet listed a welcome package running for 30 days with a headline figure of up to $2,500, plus an ongoing rewards scheme with rakeback and level-up payouts. Terms change, so read the current page before you deposit.

The key thing to understand about turnover-based rewards: you only get the big headline number if you bet a huge amount. A reward of a few percent back on the house edge is a discount on your losses, not a profit. If you'd bet €200 over a month anyway, it's a small bonus. If it tempts you to bet €2,000, it's costing you.

Crypto adds its own costs too: network fees on deposits and withdrawals, minimum withdrawal amounts, and the fact that offers are usually priced in US dollars while your bills are in euro. Our guide to crypto withdrawals covers those in more detail.

What Ireland's new rules mean for sign up offers

Ireland's new gambling regime is now in force for online betting. The GRAI began taking licence applications in February 2026, and the first remote betting licences took effect on 1 July 2026. The Gambling Regulation Act 2024 brings in much tighter controls on advertising and on inducements such as free bets and bonuses that encourage people to gamble, or to keep gambling.

How those rules play out in practice is still settling, so expect the welcome offers on Irish-licensed apps to look different from what you remember, and possibly to shrink. Offshore sites like the ones we link to aren't covered by those protections. That's worth weighing honestly: a bigger bonus from an unlicensed site comes with less protection if something goes wrong. Our page on Ireland's new gambling law has the background.

A quick way to judge any offer in two minutes

1. What do I actually get? Cash, free bet tokens, or locked bonus funds?
2. Is the stake returned? If not, value free bets at roughly 60% to 80% of face value at sensible odds.
3. How much must I wager? Multiply the wagering by the margin to get the expected cost.
4. What are the restrictions? Minimum odds, maximum bet, eligible markets, game weighting.
5. When does it expire? Seven days is common for free bets.
6. Who regulates the site? GRAI-licensed or offshore? That affects what happens if there's a dispute.
7. Would I bet here anyway? If the answer is no, the offer is pulling you somewhere you didn't want to go.

A worked comparison of three made-up offers

Say you're choosing between three welcome deals, and you'll only bet about €50 in your first month either way.

The biggest headline number, offer B, is the worst for a casual punter, because the wagering is ten times more than you meant to bet. Offer A is simple and honest. That's often the way: the plainer the offer, the more of it you keep.

Mistakes that cost people money

• Chasing the biggest number: a €500 bonus with heavy wagering is usually worth less than a €20 free bet.
• Putting free bets on short favourites: it feels safe, but you throw away most of the value.
• Depositing more than you planned to unlock the full bonus: the bonus is there to change your behaviour. Don't let it.
• Breaking a maximum bet rule: one oversized bet can void everything.
• Opening accounts all over the place: more accounts means more temptation and more places to lose track of spending.
• Using offers to chase losses: if you're signing up somewhere new to win back money you lost elsewhere, stop.
• Not keeping screenshots: grab the offer terms on the day you sign up, in case of a dispute.

Licensing and where you bet

Cloudbet, which we link to, is licensed in Curaçao and is not licensed by the GRAI. That means you won't get the protections you'd get from an Irish-licensed operator, including the GRAI's complaint and enforcement powers. Make your own decision with that in mind. Our page on whether online betting is legal in Ireland covers the legal side.

Keep it fun

A welcome offer is a sweetener, not a reason to bet. If you find yourself signing up for offers to keep betting, depositing more than you meant to, or hiding it from people close to you, take a break and talk to someone.
