Elisabeth, You'll be able to put in a few more black squares-look for places where the white squares can't possibly reach.

Elisabeth, look at the 6 in the middle. Where can it extend? 5 of its squares are forced immediately.

Also, look at the 2 at the top-right. It is the only island that can reach the 2x2 area at the very top-right of the grid, so it must extend right.

Now look at the square two to the left of that 2. Only the '4' can reach it.

Does this help?

  • 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'.
