The Gambling Commission’s 10x bonus cap was meant to end predatory playthrough rules for good, but game weighting means the true cost of clearing a bonus is often hidden in plain sight.
The 2026 Bonus Revolution that came into force on 19 January was framed as a total victory for player transparency and fairness.
As part of a package of updates to LCCP Social Responsibility Code 5.1.1, a mandatory 10x legal wagering cap was introduced to eliminate predatory playthrough requirements once and for all.
In simple terms, online casinos and bingo sites can no longer impose sky-high wagering requirements of 30x, 40x, 50x or 60x. Instead, the absolute maximum legal playthrough requirement is 10x.
This is obviously a major win for players. However, the same can’t be said for UKGC-licensed operators, who historically relied on steep wagering requirements to reclaim a significant portion of their promotional spend.
To mitigate this margin hit, casinos and bingo sites have made several strategic adjustments, most notably scaling back the headline size of match bonuses.
But their most impactful countermeasure is far more subtle: game weighting.
Game Weighting Explained
Game weighting (or contribution percentage) is the percentage of a bet that counts toward fulfilling a bonus wagering requirement.
While standard video slots almost always contribute 100% – meaning a £1 spin chips a full £1 off your remaining wagering target – other game types contribute far less.
Historically, operators used lower weightings on table games like Blackjack and Roulette to protect against high Return-to-Player (RTP) strategies. Under the old system, low weightings were simply an annoyance but under a strict 10x cap, they’ve become an operator’s primary weapon for risk mitigation.
By slashing the weighting on specific titles, an operator can stay completely compliant with LCCP SR Code 5.1.1 on paper while forcing the player to wager significantly more money in practice before cashout is permitted.
The Hard Math
To see how game weighting distorts the headline bonus cap, you have to look past the “10x” sticker price and calculate the Effective Wagering Requirement.
The formula is simple:
Nominal Cap ÷ Game Weighting = Effective Wagering
When you apply this calculation across different product verticals, the illusion of a universal 10x limit quickly disappears. Let’s use a £100 bonus as an example.
| Game Category | Nominal Cap | Typical Weighting | Total Stakes Needed (based on a £100 bonus) | Effective Wagering |
| Slots (Standard) | 10x | 100% | £1,000 | 10x |
| High RTP Slots (e.g. 98%+) | 10x | 50% | £2,000 | 20x |
| Roulette/Table Games | 10x | 10% – 20% | £5,000 – £10,000 | 50x – 100x |
| Blackjack/Live Casino | 10x | 5% – 10% (or excluded) | £10,000 – £20,000 | 100x – 200x |
The key takeaway here is that a player attempting to clear a £100 bonus on European Roulette with a 10% weighting isn’t clearing a 10x bonus – they’re playing through a 100x effective bonus.
Beyond Game Weighting: The Other Levers Operators Pull
While game weighting is the primary mathematical tool casinos use to offset the 10x cap, it isn’t the only rule hidden in the terms and conditions. Operators deploy several secondary mechanics to manage their liability, restrict player strategy and trim expected value.
This includes:
Max Bet Limits (e.g., £1 to £2 Stake Caps): Restricting max stake size prevents players from using high-variance strategies, like placing large single bets to build a rapid bankroll. Forcing small stakes requires a high volume of individual spins, allowing the game’s theoretical RTP to steadily erode the bonus balance over time. Exceeding the max bet (even by £0.50) usually results in immediate bonus forfeiture.
Aggressive Expiry Windows (24-Hour to 7-Day Clocks): Short deadlines place time pressure on the player. If you don’t complete the full turnover requirement before the timer runs out, the entire bonus balance and accrued winnings vanish.
Max Win Caps: Many offers place a hard ceiling on the total withdrawable cash generated from bonus play (e.g., “Max conversion 3x bonus value”). This completely eliminates tail risk for the operator, ensuring high-multiplier hits don’t translate into big payouts.
Excluded Games & Strategy Bans: Beyond low-weighted titles, specific mechanics are banned outright during bonus play. Hedging strategies (like simultaneously betting Red and Black on Roulette) or “progress hoarding” (collecting bonus features with bonus funds and returning with real cash to trigger them) are strictly prohibited under unfair play terms.
Payment Method Exclusions: Digital wallets like Skrill and Neteller remain widely excluded from bonus eligibility to prevent multi-accounting and bonus harvesting, forcing players onto debit cards or Open Banking options to qualify.
How to Spot and Navigate Game Weighting Traps
Now that you know how operators use game weighting and other tools to offset the 10x bonus cap, you don’t have to avoid bonuses entirely – you just need to evaluate them using the real math rather than the headline banner number.
Before opting into any promotion, run through this four-step checklist to protect your cash:
1. Calculate the “Effective Wagering” First
Never judge an offer by the headline 10x label. Take your preferred game type, find its contribution percentage in the general promotional terms and divide the nominal cap by that decimal:
Effective Wagering = Headline Cap/Game Weighting Percentage
Example: A “10x bonus” on a slot with a 50% weighting is actually a 20x bonus. If table games contribute just 10%, that “10x bonus” is secretly a 100x bonus. If the effective wagering crosses 30x, the value of the offer drops dramatically.
2. Match the Expiry Window to Your Stake Size
A 10x wagering requirement on a £50 bonus means £500 in total playthrough. If the operator imposes a £1 maximum bet limit and a 24-hour expiry window, you’ll need to complete 500 individual spins in a single day just to clear the terms. If you don’t have time for a high-volume session, pass on the offer.
3. Stick to 100% Weighted Titles
If your goal is converting bonus funds into withdrawable cash, play games that contribute 100% to the playthrough. Standard video slots usually qualify, but always check the operator’s “Excluded Games” list – casinos routinely exclude high-RTP slots (like Blood Suckers or 1429 Uncharted Seas) or drop their weighting to 10%.
4. Check the Max Conversion Limit
A low 10x wagering requirement is meaningless if the terms state “Maximum conversion: 1x bonus amount”. If you claim a £20 bonus and the max conversion is capped at £20, your potential upside is strictly limited, regardless of how lucky you get during playthrough.
Use Comparasino To Access Compliant & Fair Bonuses
The good news is that you don’t have to spend hours buried in T&Cs to find a legal, compliant offer. At Comparasino, every single online casino and bingo site we feature is manually vetted by our team to ensure it strictly complies with the Gambling Commission’s 10x wagering cap and maintains transparent, fair promotional terms.
However, because every player has different gaming preferences, operator game weighting will naturally affect everyone differently. If you prefer table games over slots, or high-RTP titles over standard games, always take a quick look at the operator’s contribution table to make sure the effective playthrough aligns with what you are comfortable with before opting in.
Martyn’s Final Thoughts
The 10x wagering cap is unquestionably one of the best regulatory shifts UK players have seen in years. It has effectively killed off the days of 50x or 60x predatory playthrough demands, bringing much-needed fairness and transparency back to online gaming.
That said, operators are businesses, and when one door closes, they inevitably adjust their risk management elsewhere. Game weighting has quickly become the primary lever casinos pull to mitigate the bonus cap and protect their exposure – turning a clean “10x cap” into a far larger commitment for non-slot players.
By taking five seconds to check how your favourite games contribute before hitting “Deposit”, you can bypass the fine-print traps, protect your bankroll and make sure a bonus genuinely works in your favour.
