General information

These explainers describe how common technology and reward schemes work in general. They are not financial, legal or technical advice. Programme terms differ and change; the provider's current terms always take priority.

Illustrative numbers

Example figures are made up to show the arithmetic. They are not real rates, prices or offers from any company.

Outside links

Outside links illustrate a point and are not endorsements. Some lead to pages in other languages, including pages from the gambling sector used as examples of how a reward is calculated.

Gambling

Mentioning a gambling site is not encouragement to gamble. Gambling is restricted by age and by law in many places; only take part where it is legal for you. Set limits and seek help if gambling stops being fun. In the US, free and confidential help is available at 1-800-MY-RESET.

Corrections

There is no helpline here. Corrections are applied when pages are revised; each page shows its revision date.
