Seven giant scratchcards have been put on billboards in Bolton and elsewhere in Greater Manchester to get the Bible message across.
People are being asked to find the missing word from a headline featuring a biblical story in The Riddle of Life competition run by the Bible Society.
The riddles are being advertised on hundreds of billboards and bus shelters as well as on trams, buses, taxis and even beer mats.
Those who solve all seven riddles stand the chance of winning £7,000 for a good cause based in the Greater Manchester area.
