Ketchup-maker Heinz has launched what it calls a 'ridiculously hard' all-red jigsaw, to help people pass the time in lockdown.

It is giving away 57 Heinz Tomato Ketchup Puzzles in 17 countries around the world - including Ireland.

The puzzle is made up of 570 pieces of all identical red.

"It might just be the world’s slowest puzzle ever made," the company says.

"As social distancing and self-isolation become the norm, a nostalgic favourite is back and trending in social feeds: the puzzle."

Emily O’Kane is marketing manager for Heinz Ireland.

She explains the thinking behind it.

"In a period when everyone has a little more time on their hands and puzzle popularity has skyrocketed, we wanted to help pass the time by connecting the two.

"We’re always looking to deliver fun, contextually relevant ways to give Heinz Tomato Ketchup lovers a smile, and this ridiculously slow, all-red Heinz Tomato Ketchup puzzle felt like the perfect fit."

Heinz is giving away 57 puzzles to ketchup lovers in 17 countries around the world.

Irish users can visit the company's Facebook, Twitter or Instagram pages for a chance to win.

The competition is running until Friday May 8th.
