Why are some games excluded from bonuses?

Why are some games excluded from bonuses? The short answer

A casino gives a bonus expecting it to cost a predictable amount. That cost depends on two things: how much wagering the terms ask for and the house edge of the games used to complete it. If you could clear the wagering requirements on a game where the casino keeps very little per pound staked, the bonus would cost the casino far more than planned. Excluding those games, or counting them at a fraction of their stake, keeps the sums in line.

That is the commercial reason. There are also practical ones (free spins are built into particular slots, progressive jackpots are funded by a shared pool) and legal ones (a casino incentive can’t include betting or bingo since the mixed-product promotion ban started). This page works through each reason with pound figures, then shows how to spot the exclusions in real terms. It sits in our casino bonus questions section, and the companion page on which games are excluded from bonuses lists the usual categories.

The cost maths: why game choice changes what a bonus is worth

Take a £50 bonus with 10x wagering, the highest multiple a UK casino can set since the 10x wagering cap arrived on 19 January 2026. You need £500 of bets before bonus winnings can be released. On average, the amount you lose while placing those bets is roughly the wagering total multiplied by the house edge. That is a long-run average, and any single session can land well above or below it.

The table shows the problem from the casino’s side. On a typical slot around 96% RTP, roughly £30 of a £50 bonus survives the wagering on average. On a game with a 1% edge, about £45 would. Multiply that difference across thousands of customers and the promotion becomes far more expensive than the marketing budget allowed for. So the operator either keeps low-edge games out of the offer or gives them a low contribution percentage, which means only part of each stake counts towards the wagering.

These figures are averages over a very large number of bets. A bonus never changes the odds of the game itself, and short sessions vary widely. Losses are the likely outcome over time.

Types of game exclusion and the reason behind each

Exclusions aren’t one rule. Casinos combine several, and the reason differs for each type of game. The table below is a general guide to how UK bonus terms tend to treat game groups; the actual list for any offer is in its own terms.

If you want the detail on particular games, see whether you can use a bonus on blackjack, whether you can use a bonus on roulette and how live casino and bonuses fit together.

Why free spins only work on certain slots

Free spins are the clearest case. A spin is credited on a specific game at a specific value, usually 10p, so it can’t simply float across the whole lobby. The casino picks the titles, and the offer terms list them as selected games. Every game outside that list is excluded automatically, which is why you generally can’t choose your free spins slot.

Our three spin-based partners show the range. PlayOJO names one game: its 80 welcome spins are on Big Bass Bonanza, a Reel Kingdom slot with a published 96.71% RTP, high volatility and a 2,100x maximum win (see our Big Bass Bonanza free spins page). Coral and Ladbrokes credit their spins on selected games that the promotion page lists; check that page rather than assuming a favourite slot is included. Our pages on Coral’s eligible games and Ladbrokes’ eligible games explain where those lists sit.

Jackpot slots: a pool that bonus money can’t fund

Progressive jackpots grow from a slice of each real-money stake, often shared across several casinos. Paying a contribution into that pool from promotional funds, or letting a 10p free spin win a pool built from cash stakes, raises awkward questions about who pays for the win. Many operators side-step this by keeping jackpot games out of their offers or by stating that free spins and bonus funds can’t win the progressive prize. Our guide to whether you can use free spins on jackpot slots explains how this tends to appear in the small print.

What UK rules say about excluded games in bonus terms

No UK rule says which games must or mustn’t count. What the rules do control is how exclusions are set out and enforced:

• Clear terms. The Gambling Commission’s social responsibility code, LCCP 5.1.1 (opens in a new tab), requires incentive terms to be clear, fair and readily accessible, alongside the 10x cap.
• No surprise bans. The Commission’s guidance on promotional play restrictions (opens in a new tab) says terms must clearly specify all prohibited types or patterns of play, and an operator mustn’t ban play that wasn’t set out in advance.
• Your own money stays free of restrictions. Commission guidance on withdrawing your deposit (opens in a new tab) says play restrictions and wagering must not apply while you play with your deposit balance.
• One product per incentive. Since 19 January 2026, the Commission’s promotions changes (opens in a new tab) stop a single offer combining casino with betting, bingo or lottery.

The CMA’s 2018 work on bonus terms pushed in the same direction, and our page on why bonus terms must be clear covers the detail.

Excluded or just weighted? How partial contribution works

Some terms don’t ban a game outright; they count only part of each stake. If a table game counts at 10%, a £10 bet adds £1 to your wagering progress. Clearing £500 of wagering that way would need £5,000 of table bets, which in practice makes the game a poor route. Our game weighting guide explains the mechanics, and do table games count towards wagering answers the common follow-up.

Weighting matters only for bonuses with wagering. Our partners Casumo (50% up to £100, 10x within 7 days) and 10bet (100% up to £25, 10x on slots within 3 days) carry wagering, so their game rules affect progress. The 10bet terms say the bonus is wagered on slots, so other games don’t move it forward. Casumo says game, play and payment restrictions apply; read its list before opting in.

What happens if you play an excluded game with a bonus

Results vary with the wording. Typical outcomes are that the bet doesn’t count towards wagering, that winnings from it are removed from the bonus balance, or, where the terms say so, that the bonus and its winnings are forfeited. Commission guidance says that where winnings are taken away, the customer should get a full explanation of the breach. Our page on what happens if you break bonus terms goes further, and the glossary entry on irregular play explains the label casinos often use.

Myths and facts about bonus game restrictions

How to check which games a bonus excludes

1. Open the offer’s significant terms box and look for words such as ‘selected games’, ‘eligible games’ or ‘excluded’.
2. Follow the link to the full terms and find the game list or the contribution table.
3. Note any per-game exclusions (jackpots, live tables, named slots) and any maximum bet that applies with the bonus active.
4. In the lobby, check that the game you plan to play appears on the list before you stake bonus funds.
5. If anything is unclear, ask customer support in writing and keep the reply.
6. If you would rather play without restrictions, decline or opt out of the bonus and play with your own balance.

Our clause-by-clause guide to bonus terms shows where game rules usually sit, and the page on the casino bonus max bet covers the stake limit that often sits next to them.

Game rules on our partners’ welcome offers

If game freedom matters to you, a no-wagering spins offer is simpler: there’s no contribution table, only a game list. Our free spins no wagering page compares the formats, and our comparison of a bonus on slots vs table games sets the two side by side.

Bonuses with simple game rules: where our partners fit

None of our partners offers a bonus that can be used on every game, so the honest comparison is about how simple the game rules are. All offers are for new customers aged 18+, and terms apply.

• Coral: deposit (some payment types excluded) and bet £10 on slots to get 100 free spins at 10p each (£10 of spins) on selected games. Accept within 48 hours; spins last 7 days; no wagering on spin winnings. PayPal, Skrill, Neteller, Paysafe, prepaid cards and certain debit cards don’t qualify.
• Ladbrokes: deposit and spend £10 on slots for 50 free spins a day for 10 days (up to 500, worth up to £50 at 10p). Claim before 23:59 each day; spins last 7 days; selected games; no wagering. PayPal, Paysafe, Skrill, Neteller, Moneybookers and prepaid cards are excluded.
• PlayOJO: a first deposit of £10 or more gives 80 free spins on Big Bass Bonanza at 10p (£8 of spins), with winnings paid as cash and no wagering. UK customers only, excluding Northern Ireland, via the designated offer link.

PlayOJO has the narrowest but clearest rule (one named game). Coral and Ladbrokes give a list to check. Gambling should stay within a budget you can afford; deposit limits and time-outs are in each account’s safer gambling settings.

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.
