The complaints claim the M&C Saatchi ad encourages bravado and could persuade young people to gamble.
Separately, the ASA has banned a Dettol Surface Cleaner TV ad which claimed: "Your chopping-board harbours 50 times more bacteria than your toilet seat."
After three viewers complained, the ASA said the ad, by Euro RSCG, "misleadingly exaggerated the dangers posed by bacteria on chopping-boards" and ruled it should not be broadcast again.
The ASA also upheld complaints against a Sky press ad that claimed "we think it's wrong to advertise attractive sounding prices that are often only available to new customers". The ASA ruled it was misleading to suggest existing customers could get as good a deal as new ones, and has told Sky not to run it again.
