Game Weighting: Why a 20x Bonus Costs $200,000 at the Blackjack Table
Published · Updated: · Gambling Websites Editorial Team
The wagering requirement in a bonus headline is a slots number. It is quoted as a single multiple — 20x, 30x, 40x — as though it applied to whatever you choose to play, and for one category of game it does. For everything else there is a second number, published separately in the bonus terms, that decides how much of each bet is actually counted.
That second number is game weighting, and it is the difference between a requirement you can clear in an evening and one you cannot clear at all.
What weighting actually is
Game weighting is the percentage of each wager that counts toward clearing a bonus. At a 100% weighting, a $10 bet advances the requirement by $10. At 10%, the same $10 bet advances it by $1. The money leaves your balance at full size either way — only the credit toward the requirement is discounted.
The arithmetic that follows is one division. Divide the stated requirement by the contribution rate and you have the real turnover for the game you intend to play.
A worked example makes the scale obvious. A $1,000 bonus at 20x playthrough is $20,000 of required turnover. On slots at 100%, that is $20,000 of slot spins. On blackjack weighted at 10%, it is $20,000 divided by 0.10 — $200,000 of blackjack, staked ten times over, to satisfy the same requirement the offer advertised as 20x.
Put the other way round: clearing $10,000 of remaining playthrough at a 10% blackjack weighting takes $100,000 wagered at the table. Nothing about the offer changed. The weighting did all of it.
The typical tiers
Weightings are set per operator and per promotion, but the shape repeats across the US market often enough to be worth recognising.
Slots usually sit at 100%. They are the highest-margin, highest-volume category, and they are where operators want bonus play to happen.
Roulette is commonly discounted to 50% at some operators and to 10% at others — this is one of the widest spreads in any weighting table, and it is a good indicator of how aggressive a given set of terms is.
Table games and video poker take the deepest cuts. Blackjack at 10% is the standard example used across US bonus guides. One published weighting scheme from a major operator runs slots at 100%, video poker at 50%, table games other than craps at 20%, and craps at 0%.
Video poker is the category to check first, because it is frequently excluded outright rather than merely discounted — the combination of low house edge and skill-dependent return makes it the least attractive game for an operator to credit.
Excluded is not the same as discounted
There is a second, harsher category, and it is regularly mistaken for a low weighting.
Some games contribute 0%. Specialty titles — bingo, keno, some video poker variants — and the highest-RTP slots in a catalogue are routinely named on an excluded list rather than given a reduced rate. A bet there does not advance the requirement slowly; it does not advance it at all.
The consequence can be worse than lost time. Many terms treat wagering on a restricted game as a breach of the promotion rather than a neutral event, and a breach puts the bonus and any winnings from it at risk of being voided. That is the practical reason to read the excluded list before the weighting table: getting the weighting wrong costs turnover, and getting the excluded list wrong can cost the balance.
The high-RTP exclusion catches people out most often, because it is counter-intuitive. The best-paying slot in the lobby is frequently the one slot that does not count.
How to read a weighting table before you deposit
Four questions, in this order, answer everything the table is there to tell you.
Which games are at 0% or excluded? Read this list first. It is the only part that can void a bonus rather than merely slow it.
What is the weighting for the game I actually intend to play? Not the headline category — the specific game. Live dealer variants are often weighted differently from the RNG version of the same game.
What is the real turnover? Requirement divided by rate. If that number is larger than the total you would stake in a month of normal play, the bonus is not clearable for you, whatever the headline says.
Is there a maximum bet while the bonus is open? A max-bet cap interacts with weighting in the way that hurts most: a low weighting demands enormous turnover, and a stake cap limits how fast you can produce it.
Why mixing games rarely rescues the maths
The obvious response to a 10% table weighting is to clear the requirement on slots and then move to the tables. That works, and it is the only sensible sequencing — but it is worth being clear about what it does and does not solve.
Contributions from different games add up. Play $8,000 on slots at 100% and $10,000 on blackjack at 10%, and you have contributed $9,000 toward the requirement. The proportions do not interact and there is no bonus for spreading play around.
What mixing cannot do is make the table games efficient. Every dollar staked at 10% is a dollar exposed to the house edge for a dime of credit, and the fastest path through a weighted requirement is always the highest-weighted eligible game you are willing to play. If you took the bonus in order to play blackjack, the honest reading of a 10% weighting is that this promotion was not designed for you.
The one line to take away
The advertised multiple describes the requirement. The weighting table describes your requirement. Any bonus can be evaluated in one division: stated requirement divided by the contribution rate for the game you plan to play, checked against what you would realistically stake anyway.
If that number is unreasonable, the offer is not a bad deal that needs negotiating — it is a slots promotion, priced as one, and the table games are in the terms to be counted slowly rather than to be played.
