Play everyday a new Str8ts game in three difficulty levels. The grid is divided into straights (horizontally or vertically consecutive cells) by black cells. Each straight contains a series of consecutive numbers (which may be in any order), e.g. 2,4,1,3, but not 5,6,9,8 (where the 7 is missing). In each row and column each number from 1 to 9 only occurs at most once. In the black cells there are sometimes clues: that number cannot be used in the white cells of that row or column.
