This month Laundry and Cleaning News International and Christeyns are giving readers of the journal a chance to enter the first of a series of Sudoku competitions.
The competitions will appear only in print in editions of LCNi. Correct entries for each competition will be put into a draw for one cash prize of £50, E75, $90 (or the equivalent).
The first competition will close by the end of May, but there will be another one in July and in the international editions of Laundry and Cleaning News.
