CBS Outdoor's new London Underground game: 150 Brands

Londoners will know how waiting for their Tube train even for two minutes can lead to utter boredom (such is the fast paced lifestyle we've adopted here), so anything to distract or engage our brains is always welcomed.

So when ad agency CBS Outdoor UK launched the Look for Longer game last year, we all lapped it up. The game, based on cryptic visual clues, was brilliant, addictive and engaging - everything an advertising campaign should be about.

Now CBS Outdoor has launched a follow up game called 150 Brands. It may not be brain teasing Look for Longerer, but after spending a brief time on the game testing my pop culture knowledge on brands, I can honestly say it's a worthy follow up. Just as long as you don't cheat.

Much like the previous game, 150 Brands game will be a cross-platform campaign, featuring heavily on the Tube network as well as the internet. Launched to celebrate 150 years of advertising on the London Underground, the game aims to engage Londoners at guessing the brands based on both products snapshots and strapline-based clues such as 'Never Knowingly Undersold' and 'Think Different'.

Players interested in entering can do so at 150brands.co.uk. Prizes includes to up to a year's worth of free travel, so how about that?
