As of 1 April, the operator – part of Ladbrokes Coral and owned by GVC Holdings – has reduced the maximum stake on fixed-odds betting terminals (FOBT) from £100 ($130) to £2.

However, Ladbrokes’ new "turbo" option allows players to wait just seven seconds for the result of its electronic roulette games instead of the previous 14.

A whistleblower told a BBC investigative report this is a "ploy to get people betting more quickly," although the new feature is optional for players and an equivalent is already widely available in online games.

Ladbrokes responded with the following statement: "Our roulette games were changed to meet the new requirements – a maximum stake of £2 and a minimum spin speed of 2.5 seconds. All of our games were changed and compliant from April 1."

Last week, Paddy Power Betfair and Betfred were both warned by the Gambling Commission after introducing new lottery games.

Gambling Insider reached out to the operators for comment and both said the products were quickly removed.
