Columbus Eggs is giving away 50 Nintendo DS Lites with the Brain Training game to underline the health credentials of its eggs.

The eggs are naturally high in Omega-3, and while the essential fatty acid's role in lowering cholesterol levels has long been recognised, Columbus is now eager to stress the importance of Omega-3 for brain health.

"This joint partnership is a great collaboration as both brands support the need for improving brain function through exercise and nutrition," said Columbus' scientific consultant Florence Lacroix.

The promotion will run until March 31.
