The National Lottery operator has removed online games of Monopoly and Scrabble from its website due to new rules designed to protect children from gambling advertising.

The restrictions – introduced by the Committee for Advertising Practice (CAP) – stop popular elements of youth culture such as sports and video games from being used in gambling ads.

It means they will not be permitted to feature or refer to top-flight footballers, celebrities, reality show stars and video games with strong appeal to under-18s.

Operator Camelot said these new rules had prompted them to make some changes, including taking away the Monopoly and Scrabble games – part of its online “instant win” portfolio.

There have been a number of different Monopoly instant win games over the years, covering different price points and with slightly different play mechanics.

The £2.50 Monopoly Gold games were developed to be similar to that of the original board game.

The player would choose from a selection of game tokens and click on the dice to enable their token to move around the board.

The games included mini games and instant prizes, and players collected property cards as they moved around the board.

In August, one player known as Mr S, from North Ayrshire, was reported to have won £100,000 playing Monopoly Gold Classic on the National Lottery app.

Karen Lucock, 56, from Carlisle, also won £100,000 playing the game after noticing she had some funds remaining in her online wallet.

A Camelot spokesperson said: “You must be over the age of 18 to register for a National Lottery online account – so no one under the age of 18 can play online Instant Win Games (IWGs) – and it’s widely recognised that the inherent risk of problem play associated with National Lottery products is very low.

“However, as a responsible operator, we’ve been reviewing our advertising over a number of months in line with the new CAP Code rules, which we knew were coming into force.

“As a result, we’ve removed – or not extended the licensing for – games such as Monopoly and Scrabble, and, for example, modified the artwork on our £300,000 Fruity Bingo and Winter Wonderlines IWGs.

“The artwork changes involved removing the images of fruit from the £300k Fruity Bingo game and removing some of the symbols.“

For example, one change involved removing a present used for the Winter Wonderlines game.

The same artwork had appeared on the details page for each game, in what it said could be deemed promotional areas of the National Lottery app and website.
