Why this version looks difficult

Sudoku is a familiar challenge to newspaper readers and puzzle enthusiasts, requiring each vertical line, horizontal line and nine-square box to contain every number from one to nine. 
While that might sound simple, the particular difficulty in this version lies in the number of deductions you have to make in order to fill in a single number on the grid.

Instead of being able to spot where a number goes based solely on the boxes that have already been filled in, most moves will face you with two or more spaces where a number could fit.

Only one of these is correct, but to find it you must examine all possible options for your next move and perhaps the move after that, continuing in the same vein until all but one potential route results in a dead end.
