Game Weighting Explained: Why Roulette Moves Nothing at All

Weighting is the proportion of a stake that counts towards a wagering requirement. Slots at 100%, tables at 0% is the standard shape across the UK market, and it is usually presented as a footnote about which games are eligible. It is not a footnote. It is the term that decides whether a requirement is difficult or effectively closed.

The strategy weighting exists to remove

Suppose a requirement of £480 has to be generated from a £12 balance, and suppose any game counted in full. The sensible approach would be low-variance play: bet £1 a hand at blackjack, where the house keeps around half a penny per pound staked on average. Four hundred and eighty hands later the requirement is met and the balance is, on average, still above £9.

That is not a loophole; it is simply what a low house edge means. And it is exactly why table games are weighted at zero on virtually every bonus in this market. Removing them does not make the requirement larger — it makes the requirement have to be generated on games where the balance either multiplies or disappears, which converts a demanding condition into one the average path does not survive.

Partial weighting

Between 100% and 0% there is a middle ground that appears more often on deposit offers than on no-deposit ones. A game at 10% means a £10 stake contributes £1 towards the requirement, so the effective requirement on that game is ten times larger than the headline. A twenty-times requirement played on a 10%-weighted game is a two-hundred-times requirement in practice, and the terms will describe it as twenty.

Anyone reading a weighting table should therefore convert it: the real multiple is the published one divided by the weighting. It is the arithmetic that makes an apparently reasonable offer occasionally impossible.

Playing an excluded game is not neutral

The intuitive assumption is that staking on a zero-weighted game simply achieves nothing towards the requirement. On many offers it does more than nothing: it breaches the terms and voids the bonus along with anything it has won. The bet is normally accepted rather than refused, which means there is no warning at the point of the mistake.

Where a casino publishes a list of excluded games while a bonus is active, that list is a restriction rather than a guide to efficiency, and it is worth reading in full before opening any game outside the slots lobby.

Where weighting stops mattering

On a wager-free offer, entirely. With no requirement there is nothing for a stake to contribute towards, so the weighting table is irrelevant and the offer can be judged on the award, the cap and the window alone. That is a substantial part of why wager-free offers are so much easier to compare, and why this site leads with them.

The chart below shows the weighting across the tracked set — which offers count tables at all, and which have closed that route completely.
