A lottery ticket has printed thereon a matrix of nine rows and nine columns defining eighty one locations some of which are pre-marked with numbers from 1 to 9 and is arranged such that the player can select and enter the numbers in open locations to provide an arrangement of the numbers in which the marked locations and the open locations contain a number selected from the numbers 1 to 9 where all columns and all rows have the nine locations thereof each containing one of the numbers 1 to 9 with each number appearing once only. Prizes are awarded, according to a set of rules relating to the lottery ticket, depending on the appearance of at least one of the numbers in at least one of the locations or depending on the total number of correct rows or columns or other matrix shape of nine locations.
