Here's how to tackle this specific puzzle: The secret is to work out how you can possibly prevent all of the top-right quarter of the puzzle from having any shaded 2x2 areas. The area between the five clues in the top-right quarter must be reached, which can only be done by three of the clues, and then the 2x2 at the extreme top-right must be reached too. Once you experiment a bit, you'll see there is only one way to complete this area, and the rest of the top of the grid. (However, there was definitely a moment when I was re-solving this just now when I wondered how on earth it was possible to fulfil that!). The remainder is then forced, working clockwise around the grid.

Key
A yellow/light blue highlight in the time distribution charts highlights your time, where relevant.
Rating scores out of 10.0 show the average difficulty rating chosen by users, where 1.0 is "Easy" and 10.0 is "Hard".
If a puzzle is opened more than once, including by loading from a saved position, then this is potentially a significant aid so it is listed as being completed with 'multiple sessions' for the purpose of the best time/average rating displays above.
Minor aid is defined as no more than one use of 'Check solution' when incomplete and/or no more than one use of 'Check solution' when wrong; and/or using highlighting aids (show repeated digits, show broken inequalities and show valid/invalid placements [slitherlink] only). Major aid is any and all other use of the solving aids except for 'show wrong'.
