As part of a "back to basics" strategy, Lego will introduce 12 Duplo products this year and launch the Quatro and Lego Baby ranges.
The products, available this summer, will be supported by marketing through its ad agency Rainey Kelly Campbell Roalfe/Y&R.
Lego confirmed that it was scrapping its Explore range because of poor sales, which contributed to annual losses of 1.4bn DKK (£129m) last year. Prior to the launch of Explore, less than two years ago, it said that pre-school toys had accounted for 20% of its turnover.
"Our Explore strategy was wrong. Customers could not find out what they were looking for. Even though Duplo still fitted with Explore's products, they did not realise and thought we had abandoned Duplo," admitted Francis Thomas, director of global media affairs for Lego.
Separately, Marketing can reveal that Lego has signed a partnership with Formula 1 World Championship-winning team Ferrari.
The tie-up, expected to be announced in the next few days, will see Lego become the F1 team's official toy partner. This will give it exclusive merchandising rights and allow it to develop six Ferrari-branded toys, which will be available this summer.
Lego will develop sets for Ferrari cars and will also launch mini figures of the team's two drivers, Michael Schumacher and Rubens Barrichello, which will be aimed at children aged seven-plus.
The Danish toy brand previously had a licensing agreement with Ferrari rival Renault Williams, which expired at the end of last season. The deal was not as extensive as the accord with Ferarri.
