Two leading UK bookmakers have pulled new high stakes betting games after a warning from the Gambling Commission.
Paddy Power and Betfred faced criticism their roulette-style games undermined new rules on fixed-odds betting.
The maximum stake on fixed-odds betting terminals was this week cut from £100 to £2, and the regulator warned against attempts to circumvent the rules.
Betfred said it wanted more talks with the commission, while Paddy Power said its game was only a limited trial.
The £2 cap on fixed-odds better terminals (FOBTs) was recommended by the Gambling Commission in March last year and is backed by the government as part of efforts to reduce gambling-related harm.
The Betfred game involved two cyclists on a screen in shops racing on a velodrome track with numbers on it.
