Normal sudoku rules apply. The grid is covered in fog. Placing correct digits reveals clues in the surrounding 3x3 area. Digits separated by a black dot are in a 1:2 ratio (ie one is double the other). Digits separated by a white dot are consecutive. Not all possible dots are given. Digits on a line form a set of consecutive, non-repeating digits - these digits can appear in any order. All lines are exactly 5 cells long, don't branch, don't share cells with other lines and only move orthogonally.
