This year marks the 15th anniversary of the adult puzzle brand.
2012 is a milestone year for Jumbo Games' Wasgij puzzle range, said MD Gray Richmond.
"Wasgij has built up a strong and loyal following over the past 15 years,” he told ToyNews.
“We wanted to mark this occasion in what is already a big year for Britain by creating a commemorative, limited edition puzzle which we are confident will be a real hit with puzzlers and a great collector’s item, too.
“The diamond promotion will also really strengthen the launch and encourage Wasgij fans to explore and enjoy the new Wasgij website.”
